PROGRESS REPORT, HYDROGRAPHY, 1893 AND 1894. [bull.131. 
observed at these points by the Weather Bureau and the Central 
Pacific Railroad Company, respectively. 
RED BLUFF STATION, ON SACRAMENTO RIVER. 
This station is located at the northeast corner of the wagon bridge 
just east of the town. It was established and is read by the Weather 
Bureau. The station is distant one-fourth of a mile from the observer's 
office m town. The gage is a painted pine plank, placed vertically, 
fastened to a sycamore tree 20 or 30 feet from the bridge. The channel 
is sandy and shifting in character. Measurements of discharge were 
made from the same bridge, but the current is very swift and is badly 
broken by the piers, introducing a probable error in the measurements 
of, say, 20 per cent. About 9 miles above Red Bluff the river is in a 
broad, uniform channel, and has a slow velocity even at high stages, 
owing to the contraction in the canyon a short distance below. The 
ferryboat is large and the bow extends several feel beyond the water 
line, resulting in favorable conditions for discharge measurements. It 
was agreed between Mr. Lippincott and the county supervisors that if 
the Geological Survey would place a gage at this point, the ferryman, 
who is paid by the county, would be instructed to report regularly the 
height of water. Below the canyon, and above both Red Bluff and 
Tehama in times of high water, the river leaves its banks, and thus 
the total amount of water is not shown by the gages. At Tehama the 
river channel is broken by the bridge piers, but not as badly as at Red 
Bluff. No canals of importance are taken out above the ferry just 
mentioned.
