Measuring rain at the wettest spot on earth

LIHU‘E — Recording rainfall is the job of the U.S. Geological Survey’s Water Resources Division.

The yearly trip to the summit of Wai‘ale‘ale was a source of high and perilous adventure ever since the task was first attempted over 100 years ago.

It first tackled by the survey’s District Engineer W.F. Martin in 1910. He trekked up the 5,080-foot mountain and placed a 50-gallon, galvanized can in the clearing overlooking Wailua. Four months later J.E. Mendes found it overflowing. So, in 1911, D.E. Homer carried a container that would measure 124 inches of rainfall up the jungle trails to the mountain’s summit — and it, too, was too small.

W.Y. Hardy tried next. He installed a 300-inch gage in 1915 and it overflowed. Next he put in a 600-inch gage which lasted a couple of years and in wet years was found to be overflowing. The history books fail to mention the party of local men that went along to carry the gage guided by Hulu Taniguchi, a cowboy at Gay & Robinson’s Makaweli Ranch. The trail would disappear just days after passing through.

Then in January 1920, District J.E. Stewart, Ben F. Rush, then chairman of the Board of Harbor Commissioners, and Hardy took the 990-inch gage up the mountain. It worked all right until it buckled and started leaking from being tipped over to empty. Max H. Carson, the next district engineer, solved that difficulty in 1928 by installing a 900-inch, reinforced container that could be drained through a valve in the bottom.

The next gage installation in 1938 was a day-to-day recording device that had to be split into 50 pound packs for the journey, the last leg on foot from the ranger’s station over the tundra-like summit. Hubert W. Beardin, an experienced mountain-climbing member of the survey force on Kaua‘i, dropped dead of a heart attack 300 feet from the summit.
