68 PROGRESS REPORT, HYDROGRAPHY, 1893 AND 1894. [bull. 131. 
VALE STATION, ON MALHEUR RIVER. 
This station is located oil the left bank of the Malheur Kiver, about 
150 feet below the junction with Bully Greek and 50 feet above the 
iron bridge now in construction. It was established by Messrs. Arthur 
P. Davis and Y. C. Tompkins on December 10, 1894. The observer 
is Mr. E. R. Murray, postmaster, Yale, Oreg. The station is distant 
from the observer's house about one-fourth of a mile. The gage is 
inclined, and is in two parts. The lower part is graduated from 1.6 to 
9.1 feet, the distance between the footmarks being 1.95 feet. The 
upper part is graduated from 9.1 to 11.7 feet, the distance between the 
footmarks beiug 3 feet. The channel is composed of earth and sand, 
and is shifting. The bench mark is on a flat rock, nearly buried, above 
the right bank of the river, 50 feet southeast of south abutment of 
new bridge, and is 1.32 feet above the 11-foot mark on the gage. In 
future, measurements are to be made from the bridge. On December 
10, 1891, the height was 1.9 feet aud discharge 128 second-feet. 
PENDLETON STATION, ON UMATILLA RIVER. 
A station was established at Pendleton, Oreg., in January, 1891, by 
Mr. A. L. Adams, -chief engineer of the Umatilla Irrigation Company, 
of Oregon. The section selected was at the point of crossing of the 
Main street bridge, the gage rod being placed on the central pier of 
the bridge. A record of the height of the stream was kept at short 
intervals for a period of over two years, daily readings being made at 
times when there were decided changes in the height of the stream. 
When, however, owing to absence of precipitation or to lack of change 
in the weather affecting the snow in the mountains, the river did not 
rise or fall notably, no readings were taken, the condition of the stream 
being watched carefully and observations taken only when necessary. 
During this period measurements of discharge by means of- floats 
were made by Mr. Adams, from which a rating table was constructed 
and the record of gage-height readings utilized in preparing a table of 
monthly discharges. These as computed extend from February, 1891, 
to July, 1892.
