Luahinewai

“Kekaha wai ‘ole na Kona” (“waterless Kekaha of the Kona district”) speaks of Kekaha, the portion of North Kona extending north of Kailua Bay from Honokōhau to ʻAnaehoʻomalu.  It is described as “a dry, sun-baked land.”

Here is Kīholo, situated within the ahupuaʻa of Puʻuwaʻawaʻa.  Kīholo (lit. the Fishhook) refers to the legend which describes how in 1859 the goddess Pele, hungry for the ‘awa and mullet, or ʻanae, which grew there in the great fishpond constructed by Kamehameha I, sent down a destructive lava flow, grasping at the fish she desired.  (DLNR)

This place name may have been selected as a word descriptive of the coastline along that part of the island where the east-west coast meets the north-south coast and forms a bend similar to the angle between the point and the shank of a large fishhook. There is no confirmation for this theory, except for our knowledge that Hawaiian place names have a strong tendency to be descriptive.  (Kelly)

While only a handful of houses are here today, in ancient times, there was a fishing village with many more that called Kīholo home.

Here, too, is Luahinewai, an anchialine pond/pool – (these are shoreline pools without surface connection to the sea, having waters of varying salinity and showing tidal rhythms (Brock.))  Luahinewai (old lady’s water) is said to refer to a water-formed supernatural moʻo (lizard) that lived there.

Of Luahinewai, JWHI Kihe writes (in Ka Hoku o Hawaiʻi; Maly:)
“There is a large pond near Kīholo and Laemanō; it is a famous bathing place of the chiefs of ancient times. The water there is cold, and causes the skin to tingle. Because it is so cold, it is like ice water.”

“It is said that there is an opening in this pond by which an old woman (luahine) enters. And there below the pond, are said to be laid out the bones of the chiefs of ancient times.”

“This pond is about five fathoms deep at its deepest point near the center of the pond. That too, is where the water is coldest. And if you should dive in and pass this area, you will find the cold water and not be able to stay there long. You will quickly retreat and wrap yourself up with a cloth.”

“The one who dives into it at its deepest point, will also see that his/her skin will turn red like the red coral. There are also pebbles at the bottoms of this pond, and it is a good thing, as you will not strike your foot upon any rocks.”

“The chiefs and fearless warriors of ancient times have passed from this side of the dark waters of death, and the bathing pool of Luahine Wai remains with its beauty, playing in the ocean mist and the gentle blowing of the breezes. This generation too, shall pass, and the next generation that follows, but Luahinewai shall remain as was found in the beginning.”

Luahinewai was a famous rest stop during canoe voyages along the coast.  (Ulukau) “… the ship sailed, pausing at Luahinewai to bathe and visit with that strange water in the lava.  After an enjoyable stop at the water with the pretty pebbles, they again sailed.”  (ʻĪʻi)

In 1790, Kamehameha I and his chiefs were living at Kawaihae. Following advice of a priest from Kaua‘i, Kamehameha undertook the reconstruction of the heiau Pu‘u Koholā, to dedicate it as a house for his god Kūkaʻilimoku.  During this time, “thousands of people were encamped on the neighboring hillsides.”

According to Kamakau, Kamehameha “… summoned his counselors and younger brothers, chiefs of the family and chiefs of the guard, all the chiefs, lesser chiefs, and commoners of the whole district. Not one was allowed to be absent except for the women, because it was tabu to offer a woman upon the altar; a man alone could furnish such a sacrifice.”

“The building of the heiau of Pu‘u Koholā was, as in ancient times, directed by an expert—not in oratory, genealogy, or the prophetic art, but by a member of the class called hulihonua who knew the configuration of the earth (called kuhikuhi pu‘uone.)”

“Their knowledge was like that of the navigator who knows the latitude and longitude of each land, where the rocks are, the deep places, and the shallow, where it is cold and where warm, and can tell without mistake the degrees, east or west, north or south. Such knowledge, taught on Kauai, one could apply anywhere in the world; so Kapoukahi had instructed Ha‘alo‘u (a chiefess relative of Kamehameha’s) to the letter.”

“As soon as the heiau was completed, just before it was declared free, Kamehameha’s two counselors, Keaweaheulu and Kamanawa (who resided at Kīholo,) were sent to fetch Keōua, ruling chief of the eastern end of the island of Hawaiʻi”

“Keōua was living in Kaʻū mauka in Kahuku with his chiefs and warriors of his guard. Keaweaheulu and his companion landed at Ka‘iliki‘i and began the ascent to Kahehawahawa … Close to the extreme edge of the tabu enclosure of Keōua’s place the two … messengers rolled along in the dirt until they came to the place where Keōua was sitting, when they grasped his feet and wept.”

“We have come to fetch you, the son of our lord’s older brother, and to take you with us to Kona to meet your younger cousin, and you two to be our chiefs and we to be your uncles. So then let war cease between you.”

Keōua agreed to accompany his uncles. Some of the party traveled by foot overland, while Keōua and some of his trusted counselors and guards traveled with the messengers by canoe.

“They left Kailua and went as far as Luahinewai at Kekaha, where they landed the canoes. Keōua went to bathe, and after bathing he cut off the end of his penis (ʻomuʻo), an act which believers in sorcery call “the death of Uli,” and which was a certain sign that he knew he was about to die.

(“The death of Uli” refers to death caused by the vengeance of the sorcerer, since Uli is the goddess worshipped by Sorcerers. The part cut off is used for the purpose of sorcery so that those who do a man to death may themselves be discovered and punished.)  (DLNR)

They kept on their course until near Mailekini, when Keʻeaumoku and some others carrying spears, muskets, and other weapons broke through the formation of the fleet, surrounding the canoes of Keōua, separating them from those of Keaweaheulu and his followers and calling to Kamanawa to paddle ahead.

Keōua rose and called to Kamehameha, “Here I am!” Kamehameha called back, “Stand up and come forward that we may greet each other.” Keōua rose again, intending to spring ashore, when Keʻeaumoku thrust a spear at him, which Keōua dodged, snatched, and thrust back at Keʻeaumoku, who snatched it away. Keōua and all those who were with him on the canoe were killed… By the death of Keōua, Kuʻahuʻula and his placing in the heiau of Pu‘u Kohola the whole island of Hawaii became Kamehameha’s.”

Kauai

Poetically the island is reportedly called, “Manōkalanipō”, or “Kauai a Manō” after the ancient chief who was largely responsible for elevating Kauai’s ancient society to sophisticated heights of advancement and productivity.  (NativeKauai)

Geologically, Kauai is the oldest of the main inhabited islands in the chain. It is also the northwestern-most island, with Oʻahu separated by the Kaʻieʻie Channel, which is about 70-miles long. In centuries past, Kauai’s isolation from the other islands kept it safe from outside invasion and unwarranted conflict.

Kauai was traditionally divided into 5 moku (districts) including: Koʻolau, Haleleʻa, Nā Pali, Kona and Puna. (Common district names that are universally used across of the Hawaiian archipelago include “Koʻolau” marking the windward sides of the islands; “Kona” – the leeward sides of the islands; and “Puna” – indicating regions where springs and fresh water abound.)

The whole of the northwest coast (Napali) show the remains of extensive agricultural work and a fairly extensive population; the Mana region had clusters of house sites in the dry valleys that cut through the cliffs. Nearly all the great river valleys are thoroughly terraced and show evidence of population.

The principal location of the house sites is on the shore line, especially near the mouths of the river valleys where the taro was growing; in the mountains are some house sites and small villages.

The principal cultivated products on Kauai were taro, sweet potatoes, yams and gourds among the vegetables, and banana, breadfruit, coconut palm and paper mulberry among the trees.  (Bennett)

Malo notes that the “cultivation of kula lands is quite different from that of irrigable lands. The farmer merely cleared of weeds as much land as he thought would suffice. If he was to plant taro (upland taro), he dug holes and enriched them with a mulch of kukui leaves, ashes or dirt, after which he planted the taro.”

“In some places they simply planted without mulch or fertilizer … If a field of potatoes was desired, the soil was raised into hills, in which the stems were planted; or the stems might merely be thrust into the ground anyhow, and the hilling done after the plants were grown.”

The boundaries of the five moku on Kauai were changed in the late-1800s to reflect the present day judicial land districts, Kawaihau, Hanalei, Waimea, Kōloa and Līhuʻe.

In 1877, Hanalei and Līhuʻe shared a common boundary.  Kawaihau was set apart by King Kalākaua, who gave that name to the property lying between the Wailua River and Moloaʻa Valley.  A bill was introduced into the legislature and the eastern end of Hanalei District was cut out and Kawaihau became the fifth district on the island of Kauai.

Though comprising only 547-square miles, Kauai is large enough to have figured at all times as a major influence on Hawaiian culture. Together with Niʻihau it forms a group which is considerably isolated from the other Hawaiian islands.  (Bennett)

Fornander notes, “the ruling families of Kauai were the highest tapu chiefs in the group is evident from the avidity with which chiefs and chiefesses of the other islands sought alliance with them. They were always considered as the purest of the “blue blood” of the Hawaiian aristocracy; … But of the exploits and transactions of most of the chiefs who ruled over Kauai during this period, there is little preserved to tell.”

He further notes that during the “nine generations from Laamaikahiki (about the 14th century – he reportedly came from Tahiti,) the island of Niihau bore about the same political relation to the mōʻi (king) of Kauai as the island of Lanai did to the mōʻi of Maui – independent at times, acknowledging his suzerainty at others. … Springing from and intimately connected with the Kauai chiefs, there was a community of interests and a political adhesion which, however strained at times by internal troubles, never made default as against external foe.”

Then things changed for Kauai and the rest of the Islands.  In the dawn hours of January 18, 1778, on his third expedition, British explorer Captain James Cook on the HMS Resolution and Captain Charles Clerke of the HMS Discovery first sighted what Cook named the Sandwich Islands (that were later named the Hawaiian Islands.)  He first landed at Waimea, Kauai.

“The height of the land within, the quantity of clouds which we saw, during the whole time we staid, hanging over it, and frequently on the other parts, seems to put it beyond all doubt, that there is a sufficient supply of water; and that there are some running streams which we did not see, especially in the deep valleys, at the entrance of which the villages commonly stand.”  (James Cook Journal)

“From the wooded part to the sea, the ground is covered with an excellent sort of grass, about two feet high, which grows sometimes in tufts, and though not very thick at the place where we were, seemed capable of being converted into plentiful crops of fine hay. But not even a shrub grows naturally on this extensive space.”  (James Cook Journal)

Throughout their stay the ships were plentifully supplied with fresh provisions which were paid for mainly with iron, much of it in the form of long iron daggers made by the ships’ blacksmiths on the pattern of the wooden pāhoa used by the Hawaiians.  The natives were permitted to watch the ships’ blacksmiths at work and from their observations gained information of practical value about the working of iron. (Kuykendall)

After a month’s stay, Cook got under sail again to resume his exploration of the Northern Pacific. Shortly after leaving Hawaiʻi Island, the foremast of the Resolution broke and the ships returned to Kealakekua Bay for repairs.  On February 14, 1779, at Kealakekua Bay, Cook and some of his men were killed.

At the time of Cook’s arrival, the Hawaiian Islands were divided into four kingdoms: (1) the island of Hawaiʻi under the rule of Kalaniʻōpuʻu, who also had possession of the Hāna district of east Maui; (2) Maui (except the Hāna district,) Molokai, Lanai and Kahoʻolawe, ruled by Kahekili; (3) Oʻahu, under the rule of Kahahana; and at (4) Kauai and Niʻihau, Kamakahelei was ruler.

Kamakahelei was the “queen of Kauai and Niʻihau, and her husband (Kāʻeokūlani (Kāʻeo)) was a younger brother to Kahekili, while she was related to the royal family of Hawaiʻi. Thus, it will be seen, the reigning families of the several islands of the group were all related to each other, as well by marriage as by blood. So had it been for many generations. But their wars with each other were none the less vindictive because of their kinship, or attended with less of barbarity in their hours of triumph.”  (Kalākaua)

Kaumuali‘i was the only son of Kamakahelei and Kāʻeo; he was born in 1778 at Holoholokū, a royal birthing heiau specifically designated for the birth of high ranking children.  Kaumuali‘i became ruling chief of Kauai upon the death of his parents.

In 1784, Kamehameha I began a war of conquest, and, by 1795, with his superior use of modern weapons and western advisors, he subdued all other chiefdoms, with the exception of Kauai.  King Kamehameha I launched his first invasion attempt on Kauai in April of 1796, having already conquered the other Hawaiian Islands, and having fought his last major battle at Nuʻuanu on O‘ahu in 1795.

Kauai’s opposing factions (Kaumuali‘i versus Keawe) were extremely vulnerable as they had been weakened by fighting each other (Keawe died and Kaumuali‘i was, ultimately, ruler of Kauai and Ni‘ihau.)  Kamehameha’s two attempts at invading Kauai were foiled (by storm and sickness.)

The island was never conquered; in the face of the threat of a further invasion, in 1810, at Pākākā on Oʻahu, negotiations between King Kaumuali‘i and Kamehameha I took place and Kaumualiʻi yielded to Kamehameha. The agreement marked the end of war and thoughts of war across the islands.

After King Kamehameha I died in 1819, Kaumuali‘i pledged his allegiance to Liholiho, Kamehameha’s son and successor.    Kaumuali‘i settled in Honolulu and became a husband of Kaʻahumanu, widow of Kamehameha I.

Hiram Bingham was on a preaching tour of the island of Kauai in 1824, shortly before King Kaumuali‘i died.  Kaumuali‘i had been living on Oahu for three years.  Bingham spoke to him just before coming to Kauai.

Bingham writes:
“We found Kaumuali‘i seated at his desk, writing a letter of business.  We were forcible and pleasantly struck with the dignity and gravity, courteousness, freedom and affection with which he rose and gave us his hand, his hearty aloha, and friendly parting smile, so much like a cultivated Christian brother.”

When the king died, Bingham said a gloom fell over Kauai.

Kaumuali‘i was buried at Waine‘e Church (Wai‘ola Church,) on Maui (he wanted to be buried near Keōpūolani, another of Kamehameha’s wives – mother of Liholiho (Kamehameha II) and Kauikeaouli (Kamehameha III.))  (King Kaumuali‘i’s granddaughter Kapiʻolani (1834–1899) married King Kalākaua.)

Kaʻōhao

Kaʻōhao (the tying) is an ʻili in the Kailua ahupuaʻa in the Koʻolaupoko Moku on windward Oʻahu.  Its name relates to when two women were tied together here with a loincloth after being beaten in a kōnane game.  (Ulukau)  The place where this act took place was given the name of Kaʻōhao and it so remains to this day.  (Fornander)

Hāuna, kahu to high chief Lonoikamakahiki of Hawai‘i Island, saw that two women were beating their husbands in a game of kōnane.  He offered to play the women and wagered a bet.  The women said to Hāuna: “We have nothing to offer on our side excepting ourselves. If you beat us in this present unfinished game you can take us as your property.”

Hāuna then said: “I have two double canoes filled with things that are valuable; the chief articles of value on the canoes, however, are a large number of feather cloaks. If you two beat me, you two shall have the goods in the canoes together with the men on board.” The women replied: “It is a bet.”

After the women were beaten at the game, he tied them together and led them to his canoes where he said to one of them:
“This canoe shall be yours with everything in it from stem to stem, including the men.  The men shall be your servants; they are not for you to sleep with. And as he had spoken to her, so in like manner he spoke to the second woman. He then left the women and proceeded to meet Lonoikamakahiki.  (Fornander)

The Hawaiians used the mountain tops between Alāla Point and Wailea Point to scan the sea for fish.  Some maps and other references note the area as Alaʻapapa and Mokulua.

In 1920, a bridge was constructed across Kaʻelepulu Stream, giving better access to the area.  Before this time, the Windward side was relatively remote.  However, in 1921, the Old Pali Road was widened and paved; this helped to initiate the suburban commute across the Koʻolau.

Shortly after (1924,) Harold Kainalu Long Castle sold land to developer Charles Russell Frazier (the head of Town and Country Homes, Ltd., which was the real estate division of the Trent Trust Co.)  Frazier (primarily a marketing man, but was also developer and chief promoter,) planned the place as a resort community of summer and vacation homes.

In the 1920s, reference to the area changed, when Frazier and Richard H Trent made up the name “Lanikai” as a marketing ploy to entice wealthy buyers looking for a vacation home at the development that was references as the “Crescent of Content”.

In naming it Lanikai they believed it translated ‘heavenly sea;’ however, they used the English word order.  In Hawaiian the qualifier commonly follows the noun, hence Lani-kai means ‘sea heaven,’ ‘marine heavenʻ.  (Ulukau)

They laid out the subdivision and the first permanent homes in the area were constructed in 1924. Development began at the northern end of the neighborhood and moved further south along the beach.

The original lots along Mokulua Drive were numbered #1 through #39, from north to south with lots approximately 75-feet in width by 250-feet in depth, and about 18,000-square feet in area.

Beachfront properties were originally sold at an extremely low price, 20-cents per square foot, because of the lack of a windbreak.

The area was initially considered a remote country location for weekend getaways or vacations at the beach for swimming, fishing, boating and hiking.

The company’s many newspaper advertisements, which encouraged Honolulu residents to escape from the city to enjoy the recreational opportunities offered by a beach home.

These ads promoted Lanikai as a tranquil place in the country, where a “beach, protected by a reef and favored by landward breezes, is always safe for bathing.” A full-page ad, titled “Lanikai Futuregraph,” placed by Trent Trust featured their vision of the future Lanikai.

There was a row of rectangular-shaped beach-front lots, bordered by the ocean on one end and the road on the other, with homes sited near the ocean and large lawns fronting the road. The first lots sold were those along the beach and the inland lots were sold later.

The construction of the Lanikai streets was completed by October 1925. Included in the deeds for the Lanikai subdivision were restrictions that remained in effect until 1950, against building within 18-feet of the property boundary line along the street or using the property for anything other than residences.

At about the same time, Frazier leased a couple-hundred acres of neighboring land from Bishop Estate.  He persuaded sixty-five men, many of whom were purchasing his lots and cottages at Lanikai, to commit to a country club project.

Before the golf course or clubhouse was even built, the Kailua Country Club (the name quickly changed to Mid-Pacific Country Club – MPCC) was heralded in the local newspaper as a “Mecca (for) tired businessmen who seek surcease from worldly cares in the surroundings of nature.” When MPCC was founded, only two eighteen-hole courses existed on the island of Oʻahu.  (mpcchi)

In 1926, the development doubled in size and Frazier added the now-iconic monument at the entrance to the development.

It was designed by the famed local architect Hart Wood.  (Wood, known for residential and commercial structures (including Alexander & Baldwin Building and Honolulu Hale,) designed the also-iconic “Hawaiian” double-hipped roof pattern and “lanai” or broad roofed-in patio with open sides.)

For decades, beach houses in Lanikai were mainly used as a retreat from Honolulu; however, in the 1950s, the area began to develop into a more suburban residential area. Many beach houses and beach retreats were replaced by houses more suited for daily living.  (The Pali Highway and its tunnels opened in 1959; that helped spark the change.)

Lanikai Beach had a white sandy beach approximately one mile long (about half of this has disappeared over the years due to erosion and seawalls along the shore.)

Battle of Kalaeʻiliʻili

In Europe, Great Britain defeated France in the Seven Years’ War (1756-1763,) becoming the dominant power in Europe, North America and India.  The war cost a lot of money; to raise funds Britain decided to levy taxes on the Colonies on the American continent.

For instance, the passed Quartering Act (required the colonies to provide barracks and supplies to British troops;) Stamp Act (taxed newspapers, almanacs, pamphlets, broadsides, legal documents, dice and playing cards;) Sugar Act (increased duties on non-British goods shipped to the colonies) and Currency Act (prohibited American colonies from issuing their own currency.)

This marked the beginning of Colonial opposition to the British (1765) and Colonists cried out against ‘taxation without representation.’

Turmoil was in the Islands, as well – some folks on Maui were also feeling that they were not being treated fairly; in addition, a power struggle was emerging.

Wailuku was considered a Royal Center (politically, ceremonially and geographically important during traditional times) with many of the chiefs and much of the area’s population residing near or within portions of ‘Īao Valley and lower Wailuku.  (FWS)

The period immediately preceding contact with the Europeans was one of considerable upheaval and conflict.  (FWS)

After the death of Kamehamehanui (the late king of Maui,, which happened about 1765, Nāmāhana (the widow queen of Kamehamehanui) married Keʻeaumoku.  (Fornander)

Nāmāhana’s brother, Kahekili, then became King of Maui, was displeased that Nāmāhana had taken Keʻeaumoku for her husband, and he became Keʻeaumoku’s enemy.

Nāmāhana and Keʻeaumoku lived at the large and fertile land of Waiheʻe.

Some people on Maui felt that the abundance of resources would have allowed all to be well fed; they felt they were not getting their share.

In particular, Kahanana (at the time, a lesser chief in Waiheʻe) was neglected by Keʻeaumoku and his court when the chief of Waiheʻe distributed fish, after fortunate catches, among the subordinates and warriors living on the land.  (Fornander)

Kalākaua writes that “Kahekili induced Kahanana … to embroil Keʻeaumoku in a difficulty with his own people.”

One evening Kahanana killed three of Keʻeaumoku’s men.  An insurrection arose and Kahekili, who was in the vicinity, took the side of Kahanana.

The resultant Battle of Kalaeʻiliʻili (c. 1765) was fought because the rich agricultural resources of the Waiheʻe River Valley and the offshore marine resources were being unevenly distributed by the chief Keʻeaumoku and other Molokaʻi chiefs.

A general fight ensued between the Kahanana party, being supported by Kahekili, and Keʻeaumoku.  Keʻeaumoku and his chiefs maintained their ground for some days, but were eventually overmatched, beaten and obliged to flee.  (Fornander)

The Battle reportedly marked the beginning of Kahekili’s reign and Keʻeaumoku and the Molokaʻi chiefs were driven out of Waiheʻe.

But the anger of Kahekili pursued the fugitives.  Invading Molokaʻi, he engaged Keʻeaumoku and his Molokaʻi allies in a sea-fight and Kahekili was again victorious. The naval engagement off Molokaʻi is called the battle of “Kalauonakukui.”  (Fornander)

Keʻeaumoku fled to Hāna, where Mahihelelima, the governor under Kalaniʻōpuʻu, received him and his wife and entertained them at Kaʻuiki.  (Fornander)

At Kaʻuiki, Keʻeaumoku appears to have found a short repose in his turbulent career; he was not heard of again for some years. It is probable that he made his peace with Kalaniʻōpuʻu and was permitted to remain at Hāna.  (Fornander)

It was later, there at Kaʻuiki, Hāna, Maui, in about 1768, that Keʻeaumoku and his wife Nāmāhana had their first child, Kaʻahumanu, future and famous Queen of Kamehameha the Great.

Again, several years pass by with Kalaniʻōpuʻu still holding portions of the Hāna district on Maui and the great fort of Kaʻuiki; but about the year 1775, the war between Hawaiʻi and Maui broke out again.  (Fornander)

Kahekili successfully defended his capital in Wailuku throughout the 1770s, until his defeat at the hands of Kamehameha’s forces.  (FWS)  (Kamehameha went on to conquer the Islands of Hawaiʻi, Maui Nui and Oʻahu by 1795 (defeating Kalanikūpule, Kahekili’s son) and ultimately ruled the island chain in 1810.)

Back on the continent, the discontent between the Colonists and the British Crown led to the American boycott of taxed British tea and the Boston Tea Party in 1773, and ultimately the American Revolutionary War (1775–1783) and then the War of 1812.

It’s Raining … Inside

The Koʻolaupoko moku (district) encompasses lands from Kualoa Point to Makapuʻu Point. Encompassing 43,598-acres (68-square miles,) Koʻolaupoko makes up approximately 11-percent of Oʻahu’s land mass.

The Koʻolau Mountain Range forms the inland (mauka) boundary of the district. The ridge elevation generally ranges from 2,500 to 2,800-feet; Kōnāhuanui, the tallest peak on the Koʻolau Mountain Range (3,150-feet) is found in Koʻolaupoko. (BWS)

Koʻolaupoko is the remnant of the Koʻolau volcano. Eruptions forming the mountains occurred approximately 2-million years ago and left lava flows that layered over each other.  Magma pouring out of fissures in the volcano solidified in the narrow cracks; the rock that is created is much denser and much less permeable than the surrounding porous lava flows.

These dense, usually vertical geological structures are known as volcanic dikes. These dikes form wall-like areas that can capture and contain water.

Trade winds, which blow over the Pacific from the northeast across the Hawaiian Islands, bring large quantities of moist air to the Koʻolau Range. When these winds are deflected up and over the range, the water vapor condenses into clouds and falls as rain.

The rainfall does one of three things: (1) it runs off, eroding the land, forming valleys and gouges in the mountain slopes (and also creates some spectacular periodic waterfalls;) (2) wets the land surface, shallow infiltration saturates the uppermost soil layer and replaces soil moisture used by plants and then is absorbed by the vegetation and/or evaporates (evapotranspiration;) or (3) it percolates into the ground (slowly sinks into the ground and becomes groundwater.)

For the latter, it takes about 9-months for the rain, now groundwater, to seep down through cracks and permeable materials in the mountain; much of the groundwater ends up contained in dikes inside the mountain.

As these dike compartments become filled with water and overflow the dike edges, sometimes the water emerges at the surface as springs or streams.

Dike water is good for drinking water.

Development of dike-impounded reservoirs for domestic water offers two basic benefits: (1) the water level is typically high (limiting pumping (as in energy to pump water up wells) and allowing gravity to distribute to the needs at lower elevations) and (2)  the reservoirs are isolated from saline water.

Groundwater impounded by dikes in the Koʻolau Range is a major source of water for the island of Oʻahu, and many tunnels have been bored into the range to develop it. (USGS)

The typical sequence of excavation of a high-altitude tunnel starts with the removal of a zone of weathered rocks, either by tunneling or trenching and is followed by penetration of dike intrusions in the basalt rock.

As tunneling advances farther and farther through the dikes and basalts, the contained dike water leaks and water flow increases, often in instantaneous jumps when key restraining dikes are punctured, until either a single dike, or a series of them, releases such a large volume of stored water that excavation must be halted.  (Mink; USGS)

When a tunnel is bored into a dike-water reservoir, if allowed to flow freely, it will drain water out of storage. Over the course of water exploration in this area, several dikes were struck.

The reduction of dike-confined groundwater storage caused by construction of eight tunnels in Oʻahu has been estimated at 25,800-Million gallons, equivalent, then, to the total ground-water withdrawal on Oʻahu for about 60 days.   (USGS)

Little consideration was given to the storage potential of dike compartments tapped and dewatered by water-development tunnels until a bulkhead was placed in a Waikāne tunnel of the Waiāhole system in 1934 to stop the draining and allow the dike to refill with water (about 40 years after high-altitude water-development tunnels were first constructed in Hawaiʻi.)

The bulkhead at Waikāne held back some water in storage, but not in sufficient volume to be considered successful. Use of the Waikāne bulkhead was discontinued, but other attempts at bulkheading were tried elsewhere, also without much success.

That changed on February 8, 1955.  A 12-foot dike 1,600 feet into the Waiheʻe tunnel was penetrated and water gushed out at an initial rate of about 2.5-mgd (million gallons per day.)   A bulkhead was built to contain the water.

The bulkhead held and the concept of inducing and controlling storage was resoundingly proved with the placement of the bulkhead in Waiheʻe tunnel.  The storage above the tunnel in Waiheʻe Valley has been estimated at 2,200-Million gallons.  (Mink; USGS)

In Koʻolaupoko, fresh water comes entirely from precipitation along the Koʻolau Mountain Range; Waiheʻe provides much of the drinking water to Windward Oʻahu, from Kahaluʻu to Kailua.

The Honolulu Board of Water Supply recently drilled an inclined well to tap dike-impounded water. This technique permitted the development of dike impounded water without the large initial and uncontrollable waste of stored water common to prior development by tunneling.

Dike tunnel systems are also at Waimānalo, Luluku, Haiku, Kahaluʻu, Pālolo, Mānoa and two Waianae tunnels, as well as in the Kohala region of the island of Hawaiʻi and in West Maui.

Oh, It’s Raining … Inside (?)

While the bulkhead holds the dike water, along the Waiheʻe tunnel into the Koʻolau, whatever the weather outside, rainwater (now groundwater) that missed the dike continues to make its downward percolation through the mountain, through cracks in the ceiling … producing a constant ‘rainfall’ for all in the darkness of the tunnel to the Waiheʻe bulkhead.

The image shows it “raining” underground in the Waiheʻe Tunnel (hawaii-edu.) In addition, I have added other related images in a folder of like name in the Photos section on my Facebook and Google+ pages.
