INTERIOR BASIN, IN NEVADA, UTAH, AND IDAHO. 
This great basin includes an area of 21 6,872 square miles, mainly in 
the State of Nevada, extending southerly into California, easterly into 
Utah, and northerly into Idaho and Oregon. The principal rivers are 
upon the east, in Utah, draining the Wasatch Mountains, and ulti- 
mately losing their waters in the Great Salt Lake. On the west are 
the rivers flowing down the steep easterly slope of the high Sierra 
Nevada, and in the center of the basin is the Humboldt. In the past a 
considerable number of measurements have been made upon the rivers 
of Utah and Nevada, and during 1893 and 1804 a few of the river 
stations previously established were maintained and others were 
located. In the following pages figures and descriptions are given 
briefly for the station at Golconda, on the Humboldt; at Battle Creek 
and Collin ston, on the Bear, and at Uintah, Provo, and Leamington, 
in Utah. 
GOLCONDA STATION, ON HUMBOLDT RIVER. 
This station is located near Golconda, Humboldt County, Nev., being 
distant from the home of the observer, Mr. L. Dutertre about If miles. 
The gage is a pine board, inclined, firmly spiked to posts driven well 
into the bank, and graduated to feet and tenths. The river channel is 
through earth; the banks are steep and moderately stable, and the 
channel is almost straight for 400 or 500 feet. The bed of the channel 
is of sand and gravel. There are two bench marks on the west side
