OPERATIONS AT THE RIVER STATIONS, 1897.-Part II
WASHINGTON, GOVERNMENT PRINTING OFFICE, 1898ARBOLES STATION ON SAN JUAN RIVER.
This station, described in the Eighteenth Annual Report, Part IV, page 279, is located at a foot bridge 1,000 feet below the
Denver and Rio Grande Railroad depot at Arboles, Colorado, and is above the month of the Peidra River. The gage consists
of two inclined 4 by 4 inch timbers marked to vertical tenths of a foot, the space between marks being 0.131 of a foot, and
it is bolted to the rocky bank on the right-hand side of the river. The left bank is low and liable to overflow, the right
is high and rocky; the current is sluggish, and the bed sandy and shifting. Discharge measurements are made during high water
at the footbridge, and at low stages about 1,300 feet below the gage, where the bed of the stream is composed of small stones
and is less liable to change, and the current is swift. The observer is T. F. Burke, section foreman. The following discharge
measurements have been made in 1897 by Cogswell:
April 25, gage height, 8.30 feet; discharge, 2,753 second-feet.
May 16, gage height, 8.80 feet; discharge, 3,316 second-feet.
June 27, gage height, 7.60 feet; discharge, 1,604 second-feet.
July 25, gage height, 6.50 feet; discharge, 446 second-feet.
August 29, gage height, 5.80 feet; discharge, 209 second-feet.
September 26, gage height, 8.00 feet; discharge, 2,048 second-feet.
October 24, gage height, 6.90 feet; discharge, 795 second-feet.

BUTTES STATION ON GILA RIVER.
This station, described in the Eighteenth Annual Report, Part IV, page 286, is located at the buttes 16 miles above Florence,
Arizona. This gage is bolted to a solid rock on the right bank, where the river emerges from the lower end of the gorge.
Measurements are made from a car suspended from a cable, a short distance above the gage. Owing to the shifting character
of the bottom, it was necessary to make a large number of discharge measurements and the following were made by W. J. Brash
and A. T. Colton in 1897:
