Hāmākua Ditch

As a result of the 1902 Arthur S Tuttle report commissioned by the Bishop Estate to study the feasibility of bringing water to the Hāmākua area, two major ditches were proposed – the Upper Ditch and the Lower Ditch.

“The object of the Hawaiian Irrigation Company, Limited, is in brief, the supplying of mountain water, by means of one upper and one lower irrigation canal, from the large watershed and permanent streams of the Kohala mountains, Hawaii …”

“… to the sugar estates in the Hāmākua district, where a large area, which is capable of considerable extension, is now under cultivation.” (Hawaiian Star, July 2, 1910)

The Hawaii Irrigation Company was originally known as the Hāmākua Ditch Company, Ltd., which was incorporated on February 9, 1904. Among the local bond subscribers were FA Schaefer & Co, Honokaa Sugar Co, Pacific Sugar Mill, Allen & Robinson, H Hackfeld, Mr Ahrens and Mr Jorgensen.

Sometime between August 1908 and April 1909, the Hāmākua Ditch Company changed its name to Hawaiian Irrigation Company, Ltd.

“Efforts to obtain water on a large scale for the ‘dry’ Hāmākua section of Hawaii had begun, however, prior to the active association of Mr. McCrosson with the projects. In 1884 Claus Spreckels, WG Irwin, HP Baldwin and others had surveys made and did considerable preliminary work, but the scheme was abandoned owing to the decision of Mr. Baldwin to concentrate his energies and capital upon the island of Maui.”

“In 1892 LA Thurston, then minister of the interior, made an official survey of the country (with a view to devising a scheme for taking water into Hamakua.) These several surveys formed the basis of Mr McCrosson’s later operations and the survey basis of the three great systems as they appear today.” (Hawaiian Star, July 2, 1910)

Water sources for the Upper Hāmākua Ditch were the Kawainui and the Alakahi streams, as well as general runoff from the watershed into the ditch; construction apparently commenced in April 1906. The Ditch was completed in January of 1907 and was initially able to deliver 15 MGD (million gallons per day.)

John T McCrosson oversaw the construction of the ditch. The Upper Ditch was approximately 23-miles in length and some 15 miles of it ran through Honokaa Sugar Co. and Pacific Sugar Mill land. Originally the Upper Ditch consisted of dirt ditches and galvanized flumes patched with lumber.

The Lower Ditch construction began in June 1907 (water sources were the Kawainui, Alakahi, Koeawi, and later, the Waimea streams,) but serious construction work did not start until September 1908. The ditch was opened on July 1, 1910 with a delivery of 30 MGD.

It was the occasion of two days of banquets, speeches and merry-making … “According to rumors aboard the Mauna Kea, the Hamakua Ditch opening on Friday will be the scene of an immense gathering, if the weather be favorable. It is understood that the entire population of the district will foregather there…” (Hawaiian Star, June 30, 1910)

The original length of the Lower Ditch was approximately 24 miles. Later on it was extended about 5 miles to supply water to Pauʻuilo Plantation.

“(F)rom the water head to the exit from Waipio Valley a distance of nearly nine miles, the ‘ditch’ is no ditch at all but a continuous tunnel with only three breaks where it comes out of the face of the bluff to span a narrow gorge and plunge into the face of the opposite precipice once more to bury itself in the lava depths …”

“… and that there are as yet unused possibilities for the incidental development of 8000 horsepower which can be distributed as electric energy all over the Island of Hawaii, give some conception of what the Great Ditch means.” (Hawaiian Gazette, July 5, 1910)

Japanese laborers built the ditch tunnels, the tunnel of the Lower Ditch, traveling the 8.9-miles from the Kawainui intake to the weir at Kukuihaele, was one of the longest in Hawai‘i. It was further distinguished by being quite large, approximately 10 X 12 feet in diameter. In 1920, another tunnel was constructed through Lalakea Gulch.

Apparently, three people were killed as a result of the building of the ditch. In July 1909, an engineer, Thomas F Kelly, drowned (with his horse) in Waipi`o Valley as he was returning from Kukuihaele with supplies.

A month later, a Japanese laborer was “pinned down by a large rock falling on him; he died shortly after the accident.” There is mention of a third, a Japanese workman, who, during the cutting of a trail across the face of the pali, was struck by a falling rock, “and he tumbled to death hundreds of feet below.” (EnvHawaii)

Due to various disputes , by February of 1915, Hawaiian Irrigation Co. was taken over by new management (essentially that of Honokaa Sugar Co.)

The company became involved in the growing and selling of rice. A rice mill was operated and became a source of revenue. There were also a few small independent poi factories located in the valley. The records also reflect other attempts regarding diversified agriculture in the valley.

In 1960, Honokaa Sugar Co. bought the remaining outstanding shares of the Hawaiian Irrigation Company, making Hawaiian Irrigation Company a wholly owned subsidiary of that firm.

For half a century it was the sole source for potable water for the communities along its path. The Hāmākua Ditch is woven into the history and culture of the local communities beyond its length. The ditch continues to serve the needs of the Hāmākua community.

The demise of the sugar industry, including the closure of Hāmākua Sugar in 1994, left a void in communities on the Big Island and throughout the state. At that time, the community expressed a strong desire to retain an agricultural lifestyle, which helped define the character of the community.

A movement toward growing a diversified agricultural community began with an eye on the highly desirable lower elevation lands. The Hāmākua Ditch remained a critical and important piece in this vision.

The Hamakua Ditch Work Group (comprised of local farmers and ranchers, representatives from the Hāmākua Farm Bureau and Hāmākua/North Hilo Cooperative, USDA Natural Resource Conservation Service, State Department of Agriculture, State Legislators and Kamehameha Schools) formed shortly after the 1994 closing of the plantation and has focused on maintenance and preservation of the Hāmākua Ditch system. (Takamine)

“John T McCrosson, the builder of the Hāmākua ditch, was born In Delaware, and arrived in the Islands first in March, 1880, going to Kohala plantation, where he had charge of theo traction engines. Remained there and at other plantations until 1885, when he went to San Francisco and engaged in the machinery business.”

“While at Kohala, Mr McCrosson studied deeply into the water problem of that rich country, and worked out during the years at San Francisco the great systems which are now under way there.”

“He returned to the Islands in 1895 and, with the exception of business visits to Washington, London, and other cities, has been here ever since. The Kohala ditch was the first planned and carried out by Mr. McCrosson.”

“This was completed June 11, 1906, and was the occasion of a monster ‘celebration’ in which almost the whole Island of Hawaii joined.” (Hawaiian Star, July 2, 1910) (Lots of information here is from HSPA, EnvHawaii and Takamine.)

Ka Waʻa O Maui

The Wailuku is the longest river in Hilo (twenty-six miles.) Its course runs from the mountains to the ocean along the divide between Mauna Kea and Mauna Loa. The Wailuku is the boundary between Hilo Palikū in the north and Hilo One on the south.

There are many vague stories as to why the Wailuku River was so named. Wailuku literally means “destroying water.” Legends connected with the Wailuku tend to confirm the belief that it was named for its violent habits.

In olden times before there were bridges and other safeguards, the river wrought considerable damage to property and during the rainy season it took its toll of human lives. (Hapai)

Waiānuenue Avenue (rainbow (seen in) water) is named for the most famous waterfall, Ka Wailele ʻO Waiānuenue, Rainbow Falls on the Wailuku River. The goddess Hina once lived in the cave beneath and behind the waterfall. Maui was her son.

The stories of Maui are common old tales and speak of a real voyager who traveled throughout the islands of the Pacific, a sailor of great renown deified for his deeds; hence, the commonality of the tale.

He raised the islands the same way sailors have always raised islands, by sailing towards it until the land rises from the sea above the horizon. The story of Maui is a tale of discovery. (Kaulukukui)

In many of the accounts Maui is a mischievous trickster, stealing the secret of fire and helping his mother to dry kapa by lassoing the sun to slow its progression across the sky. (Bishop Museum)

It is on the Wailuku River that we still see the evidence of Maui in Hilo – Ka Waʻa O Maui – the Canoe of Maui.

Far above Rainbow Falls, in the bed of the river, dwelt Kuna. The district through which that portion of the river runs bears to this day the name “Waikuna” or “Kuna’s river.” Kuna was a mo’o (lizard, reptile of any kind, dragon, serpent; water spirit.)

Kuna often tormented Hina in her rocky cave behind Rainbow Falls by sending over great torrents of water or by rolling logs and boulders down the stream. Quite often he would block the stream below the falls to dam the river and drown Hina.

But Hina was well protected. Her cave was large and the misty cloud of spray from the falling waters helped to conceal it. So in spite of the frequent floods and many threats from Kuna, Hina paid him little attention.

On many days Hina was alone, while her son, Maui, was away on one of his numerous expeditions. Even then she did not mind this, for should any danger befall her she had a peculiar cloud servant which she called ao-o-pua (a sharp pointed cloud.)

If Hina were in trouble this ao-o-pua would rise high above the falls, taking an unusual shape. When Maui saw this warning cloud he would hurry home at once to his mother’s side.

One night while Maui was away from home on the Island of Maui, where he had gone to bargain with the Sun, a storm arose. The angry waters roared about the mouth of Hina’s cave.

Kuna, aware of the situation, was quick to take advantage of the situation. Calling upon his powers he lifted an immense boulder and hurled it over the cliffs. It fitted perfectly where it fell between the walls of the gorge and blocked the rush of the hurrying torrent.

Hina slept until the cold waters entered the cave, rapidly creeping higher and higher until they reached her where she slept.

Startled, she sprang to her feet, and her cries of panic resounded against the distant hills. Again and again, her voice went out from the cave. It pierced through the storms and the clouds. It swept along the side of the great mountain. It crossed the channel between the islands of Hawaii and Maui.

Ao-o-pua rose swiftly above the falls when Hina cried for aid and then, assuming a peculiar shape, stood high above the hills that Maui might see it.

Through the darkness Maui could see the strange warning cloud, unusually large and mysterious. With his mother’s cries ringing in his ears he bounded down the mountain to his canoe. Pushing it into the sea, with two mighty strokes of his paddle, he crossed the sea to the mouth of the Wailuku river.

A long, narrow rock in the river, called Ka Waʻa O Maui (The Canoe of Maui), is still just where he ran it aground at the foot of the rapids.

Leaving his canoe, Maui seized the magic club with which he had conquered the sun after lassoing him, and rushed along the dry bed of the river to the place of danger. Swinging the club swiftly around his head, lie struck the dam holding back the water of the rapidly-rising river.

“Ah! Nothing can withstand the magic club. The bank around one end of the dam gives way. The imprisoned waters leap into the new channel. Safe is Hina the goddess.”

Hearing the crash of the club and realizing his attempt on the life of Hina had again failed, Kuna turned and fled up the river. Maui rushed up the river to punish Kuna for the trouble he had caused Hina.

Kuna fled to his different hiding places, but Maui broke up the river bed and drove the dragon out from every one, following him from place to place as he fled down the river.

At last Kuna found what seemed to be a safe hiding place in a series of deep pools, but Maui poured a lava flow into the river. He threw red-hot burning stones into the water until the pools were boiling and the steam was rising in clouds. Kuna uttered incantation after incantation, but the water scalded and burned him.

Dragon as he was, his hard, tough skin was of no avail. The pain was becoming unbearable. With cries to his gods he leaped from the pools and fled down the river. The waters of the pools are no longer scalding, but have never lost the tumbling, tossing, foaming, boiling swirl – today this area is known as ‘The Boiling Pots.’

With joy at the sight of Kuna’s body hurled over the falls, they eagerly watched the dragon as the swift waters swept him against the dam with which he had hoped to destroy Hina. Maui had saved Hina.

Across Polynesia, almost every group has its own versions of the tales of Maui, including Maui’s canoe. For instance, Maori note “Te Waka-a-Maui” (“the Canoe of Maui”) as an ancient name for the South Island of New Zealand.

‘It’s Different’

These weren’t the words expected by the questioner in my response to what I thought about my first trip into the Northwestern Hawaiian Islands (now the Papahānaumokuākea Marine National Monument.)

I think she was expecting words like: spectacular, pristine, resource rich, special, abundant, etc.

Yes, it’s all those descriptors, too; and for me, therefore, “different.”

I wasn’t trying to be cute, but, rather, acknowledge the responsibility we faced in protecting this place.  (I have been to the Northwestern Hawaiian Islands several times, each time reinforced the feeling.)

My first trip – a 3 ½ plane ride there, 3 ½ hours on the ground and 3 ½ hours back – was to Tern Island at French Frigate Shoals (it looks like an aircraft carrier in the reef.)

French Frigate Shoals is the largest atoll in the chain, taking the form of an 18-mile long crescent. It is estimated to be 12.3 million years old.

Tern Island (approximately 30-acres) in the atoll is the site of a Fish & Wildlife Service field station, which occupies a former U.S. Coast Guard Long-Range Aids to Navigation (LORAN) station that closed in 1979.

A relatively deep (80 to 100 feet) coral reef at this atoll has been recently discovered to function as a spawning site for Ulua (the giant trevally); a rare discovery of spawning sites for top predators.

The lagoon is also unusual in that it contains two exposed volcanic pinnacles representing the last vestiges of the high island from which the atoll was derived, as well as nine low, sandy islets.

The sand islets are small, shift position, and disappear and reappear. These islets provide important habitat for the world’s largest breeding colony of the endangered Hawaiian monk seal.

On a tour around Tern Island we saw monk seals and turtles resting on the sandy shore, as well markings in the sand of a turtle who laid her eggs the night before.

And lots of birds … mostly terns —> Tern Island.

On that trip, we were unexpectedly greeted by Jean-Michel Cousteau; he was on the island during his filming of “Voyage to Kure.”

Here’s a link to the Google ‘Street View’ on Tern Island.

I also visited Midway.  Look at a map of the Pacific and you understand the reasoning for the “Midway” reference (actually, it’s a little closer to Asia than it is to the North American continent.)

Kuaiheilani, suggested as a mythical place, is the traditional name for what we refer to as Midway Atoll.  Described in the legend of Aukelenuiaiku, the origin of this name can be traced to an ancient homeland of the Hawaiian people, located somewhere in central Polynesia.  (Kikiloi)

According to historical sources, this island was used by Native Hawaiians even in the late-1800s as a sailing point for seasonal trips to this area of the archipelago.

The Northwestern Hawaiian Islands, and in particular Midway Atoll, became a potential commodity in the mid-19th century. The United States took formal possession of Midway Atoll in August of 1867 by Captain William Reynolds of the USS Lackawanna.

Midway’s importance grew for commercial and military planners. The first transpacific cable and station were in operation by 1903. In the 1930s, Midway became a stopover for the Pan American Airways’ flying “clippers” (seaplanes) crossing the ocean on their five-day transpacific passage.

The United States was inspired to invest in the improvement of Midway in the mid-1930s with the rise of imperial Japan. In 1938 the Army Corps of Engineers dredged the lagoon during this period and, in 1938, Midway was declared second to Pearl Harbor in terms of naval base development in the Pacific.

The construction of the naval air facility at Midway began in 1940. At that time, French Frigate Shoals was also a US naval air facility. Midway also became an important submarine advance base.

While I was Chair at DLNR, we created the Refuge rules whose intent is “To establish a marine refuge in the Northwestern Hawaiian Islands for the long-term conservation and protection of the unique coral reef ecosystems and the related marine resources and species, to ensure their conservation and natural character for present and future generations.“  Fishing is prohibited.

This started a process where several others followed with similar protective measures.  The BLNR unanimously adopted the State’s Refuge rules, President Bush declared it a Marine National Monument and UNESCO designated it a World Heritage Site.

Some ask why we imposed such stringent limitations on use in this area.  For me, it ended up to be pretty simple; it is the responsibility we share to future generations, to allow them to see what it looks like at a place in the world where you don’t take something.

Moku Manu

About 2-million years ago, much of the northeast flank of Koʻolau volcano was sheared off and material was swept onto the ocean floor (named the Nuʻuanu Avalanche) – one of the largest landslides on Earth.

The Pali is the remaining edge of the giant basin, or caldera, formed by the volcano. Mōkapu Peninsula (where Marine Corps Base Hawai‘i is situated) is evidence of subsequent secondary volcanic eruptions that formed, among other features, the islet of Moku Manu.

The majority of seabird-nesting colonies in the main Hawaiian Islands are located on the offshore islands, islets and rocks. Many of these offshore islands are part of the Hawaii State Seabird Sanctuary System.

These sanctuaries protect seabirds, Hawaiian Monk seals, migrating shorebirds, and native coastal vegetation. These small sanctuary areas represent the last vestiges of a once widespread coastal ecosystem that included the coastlines of all the main Hawaiian Islands. (DLNR)

Hawaiian seabirds today are subject to a number of threats to their survival, including predation by introduced mammals, habitat loss and degradation, and human impacts by people trespassing in seabird nesting areas.

Moku Manu (Bird Island) is three-quarters of a mile off Mōkapu Peninsula. It’s aptly named; it has the most diverse and one of the densest seabird colonies in the Main Hawaiian Islands. The state designated it the Moku Manu State Wildlife Sanctuary. (DLNR)

It is home to Uʻau Kani or Wedged-Tailed Shearwater, Noio or Black Noddy, Noio kōhā or Brown Noddy, ʻOu or Bulwer’s Petrel, Koaʻe ʻula or Red-tailed Tropicbird, ‘Ewa ʻEwa or Sooty Tern …

… ʻIwa or Great Frigatebird, Christmas Shearwater, Pākalakala or Grey-backed Tern, ʻā or Masked Booby, ʻā or Brown Booby, ʻā or Red-footed Boobies and various common shorebird species. (DLNR)

Moku Manu is protected as a state seabird sanctuary like its neighbors to the south, Manana, Kāohikaipu, and Mōkōlea Rock. “It is prohibited for any person to land upon, enter or attempt to enter, or remain in any wildlife sanctuaries …” Regardless, landing by boat is nearly impossible due to the lack of a safe beach.

The island is actually of two parts; the main western one is about 18 acres in extent and the smaller outer part is about three acres.

It has a relatively flat top, averaging about 165 feet in height but running up to 202 feet. The cliffs of Moku Manu drop directly into the sea around more than half of the island.

Moku Manu is perhaps the least accessible to humans of any of O‘ahu’s offshore islands. This fact seems to explain to an important degree the breeding of several species there that do not nest on any other of Oahu’s offshore islands.

Due to the challenging accessibility onto the island, it is rarely visited by unauthorized persons and not often by others (it is prohibited by law to go onto the island without a permit.)

During the last century or more, when the bird populations of more accessible offshore islands were depleted by man, and domestic plants and mammals sometimes introduced, Moku Manu remained relatively free from such influences.

The much longer canoe trip (there are no beaches near the head of Mōkapu Peninsula opposite Moku Manu,) the rough channel, and the uncertainty of being able to get on the island must have combined to keep even the old Hawaiians away much of the time. (Richardson & Fisher, 1950)

I grew up on Kaneohe Bay (on the other side of Mōkapu Peninsula from Moku Manu). No one sailed in our family. Except, as a pre-/early-teen, we did get a car-toppable Sunfish that I used to sail by myself in the Bay, usually in the main basin of the Bay.

However, one day I cruised to Coral Island, then ventured a bit more out the Crash Boat Channel to Turtle Back. And, from there, in the distance, I saw another target, Moku Manu.

After a while, and about halfway to Moku Manu, I realized this was probably not a good idea; folks at home thought I was leisurely cruising in the Bay, now I was in blue water, well outside the Bay.

No one knowing, no life jacket, no radio … a kid with no brains. However, the challenge was there and I eventually circled the island, and its birds, and safely headed home.

Land Divisions

In discussing ancient land divisions, we typically hear of Mokupuni (island,) Moku (district,) Ahupuaʻa (generally watershed units) and ʻIli (strips of land.) Kalana and ʻOkana are often less-heard-of land divisions.

“In very ancient times, the lands were not divided and an island was left without divisions such as kalana, ʻokana, ahupuaʻa, and ʻili, but in the time when the lands became filled with people, the lands were divided, with the proper names for this place and that place so that they could be known.” (Kamakau)

Each of the larger divisions of this group, like Hawaiʻi, Maui and the others, is called a mokupuni (moku, cut off, and puni, surrounded.)

Six districts on the islands of O‘ahu and Hawai‘i, and the system of developing smaller manageable units of land became formalized by the early 1600s, in the reigns of ʻUmi-a-Līloa and Māʻilikūkahi. (Maly)

“The island (moku that is surrounded by water) is the main division, like, Hawai’i, Maui and the rest of the island chain. (Islands) were divided up into sections inside of the island, called moku o loko, like such places as Kona on Hawai’i island, and Hana on Mäui island, and such divisions on these islands.” (Malo)

Over the centuries, as the ancient Hawaiian population grew, land use and resource management also evolved. The moku puni or islands were subdivided into land units of varying sizes.

Each island was divided into several Moku ʻĀina (moku-o-loko (district – literally: interior island)) (Moku) or Districts. The Moku and Kalana (similar to the Moku) were divided into ʻokana (divisions within a Moku or Kalana) and Ahupuaʻa.

There sections were further divided into subdivision called ʻokana, or kalana. On the intermediate level, some kalana/moku were subdivided into ʻokana, some ʻokana were apparently independent of any moku/kalana, and moku and kalana were not always synonymous but appear in some cases to have been units nested within each other. (Beamer)

“(A) poko is a subdivision of a ʻokana. These sections were further divided into smaller divisions called Ahupua’a, and sections smaller than an Ahupua’a were called ‘ili ‘āina.” (Malo)

There is a district called Kona on the lee side, and one called Koʻolau on the windward side of almost every island. On Maui there are some sub-districts called ʻokana, of which there are five in the Hana district, while Lahaina is termed a Kalana. (Alexander)

Despite the diversity and complexity of the system, it appears that the ahupua’a became the most important division in the resource administration of the Hawaiian Kingdom, both as a unit and as a reference for the location of smaller properties. (Beamer)

Ahupuaʻa are subdivisions of land that were usually marked by an altar with an image or representation of a pig placed upon it (thus the name ahu-puaʻa or pig altar.)

In their configuration, the ahupua‘a may be compared to wedge-shaped pieces of land that radiate out from the center of the island, extending to the ocean fisheries fronting the land unit.

Their boundaries are generally defined by topography and geological features such as pu‘u (hills), ridges, gullies, valleys, craters, or areas of a particular vegetation growth.

The ahupua‘a, like the larger districts they belonged to, were also divided into smaller manageable parcels. Among the smaller land units that were identified by the ancient Hawaiians were the: ‘ili lele and ‘ili kupono. (Maly)

A peculiarity of the ‘Ili, on Oʻahu at least, is that it often consists of several distinct sections of land in different parts of the Ahupua’a, which are called lele, i.e. ‘jumps.’

Thus many lands in Waikiki have their corresponding patches of taro land and forest in Waikiki and Manoa valleys. The taro lands of Wailupe are found in Palolo valley. In Kalihi, and also in the district of ʻEwa, are ʻili which consist of eight or ten scattered lele apiece, included under one title. (Alexander)

ʻIli were detached parcels with resources in various environmental zones; kihāpai, both lo‘i (pond fields) and dry gardens; māla, dryland agricultural systems; and kōʻele, agricultural parcels worked by commoners for the chiefs.

These smaller parcels were inhabited and managed by the makaʻāinana (people of the land) and their extended families. In each ahupua‘a—from mountain slopes to the ocean—the common people were generally allowed access to all of the various natural resources within a given ahupua‘a. (Maly)

Land Divisions include, generally:

• Mokupuni – The island groups (such as our current county system)
• Moku – The major districts of each individual island
• Kalana – The significant divisions within each Moku
• ʻOkana – Division of the Moku or Kalana
• Ahupua‘a – Individual watershed regions within each Kalana
• ʻIli – functional subdivisions of an Ahupua‘a
