USGS Water-Resources Investigations Report 93-4076


Description, qualifying comments, and acceptable water years.

Drainage area is 162 sq.mi.                             Datum is 4300.00 ft.
Located in hydrologic unit 18020003 at Latitude: 40:41:12N  Longitude: 121:25:25W
Station is in the state of CA (county code 089) and serviced by the CA office.
Channel slope is 206.20 feet/mile
Stream length is 19.40 miles
Mean basin elevation is 6140.00 feet above National Geodetic Vertical Datum
Percent of contributing drainage area covered by 
   Storage: 0.00%     Lakes: N.A.%        Forests: 91.00%     Glaciers: N.A.%
Soil infiltration index is N.A. inches
Annual precipitation is 43.00 inches
Precipitation intensity is 3.50 inches/24 hour (expected on the average once each two years)
January minimum temperature is 20.00 degrees Fahrenheit
Comments and qualifications on the data:
   Diversions for irrigation of 260 acres. Hydrologic drainage boundary uncertain owing to ground water exchange. 
   Volcanic terrain produces high base flow and anomalous patterns in runoff.

Daily and longer averages for 61 water years are acceptable (all years except partial years).
A water year with acceptable data is indicated by an asterisk in the time line, which spans 1874 through 1988.
