USGS Water-Resources Investigations Report 93-4076


Description, qualifying comments, and acceptable water years.

Drainage area is 102 sq.mi.                             Datum is 340.00 ft.
Located in hydrologic unit 02070009 at Latitude: 39:36:45N  Longitude: 077:14:10W
Station is in the state of MD (county code 013) and serviced by the MD office.
Channel slope is 12.80 feet/mile
Stream length is 28.00 miles
Mean basin elevation is 625.00 feet above National Geodetic Vertical Datum
Percent of contributing drainage area covered by 
   Storage: 0.02%     Lakes: N.A.%        Forests: 17.00%     Glaciers: N.A.%
Soil infiltration index is 3.07 inches
Annual precipitation is 43.50 inches
Precipitation intensity is 3.10 inches/24 hour (expected on the average once each two years)
January minimum temperature is 23.50 degrees Fahrenheit
Comments and qualifications on the data:
   Only monthly average discharge values were available for October and November of 1947, and daily values were
   estimated by the monthly value for those two months of "constant" flow.

Daily and longer averages for 41 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.
