USGS Water-Resources Investigations Report 93-4076


Description, qualifying comments, and acceptable water years.

Drainage area is 395 sq.mi.                             Datum is 906.84 ft.
Located in hydrologic unit 03010101 at Latitude: 37:15:30N  Longitude: 079:56:20W
Station is in the state of VA (county code 770) and serviced by the VA office.
Channel slope is 17.40 feet/mile
Stream length is 45.30 miles
Mean basin elevation is 1680.00 feet above National Geodetic Vertical Datum
Percent of contributing drainage area covered by 
   Storage: 1.03%     Lakes: N.A.%        Forests: 74.00%     Glaciers: N.A.%
Soil infiltration index is N.A. inches
Annual precipitation is 42.20 inches
Precipitation intensity is 3.13 inches/24 hour (expected on the average once each two years)
January minimum temperature is 26.30 degrees Fahrenheit
Comments and qualifications on the data:
   Records prior to 1949 are unsuitable for analysis at less than monthly resolution due to diurnal fluctuations at
   low flow induced by upstream power plants.

Monthly and longer averages for 70 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.
