USGS Water-Resources Investigations Report 93-4076


Description, qualifying comments, and acceptable water years.

Drainage area is 309 sq.mi.                             Datum is 50.07 ft.
Located in hydrologic unit 08050003 at Latitude: 32:25:55N  Longitude: 091:22:00W
Station is in the state of LA (county code 065) and serviced by the LA office.
Channel slope is 1.10 feet/mile
Stream length is 44.40 miles
Mean basin elevation is 84.00 feet above National Geodetic Vertical Datum
Percent of contributing drainage area covered by 
   Storage: 8.00%     Lakes: N.A.%        Forests: 55.00%     Glaciers: N.A.%
Soil infiltration index is N.A. inches
Annual precipitation is 52.00 inches
Precipitation intensity is 4.50 inches/24 hour (expected on the average once each two years)
January minimum temperature is 37.00 degrees Fahrenheit
Comments and qualifications on the data:
   Period of good record is from 1955 to present. There is small diversion upstream for irrigation and the system of
   interconnected bayous and drainage ditches produces interchange of streamflow under various conditions. Monthly
   average discharge measurements should not be significantly altered.

Monthly and longer averages for 34 water years are acceptable (some whole years and all partial years are excluded).
A water year with acceptable data is indicated by an asterisk in the time line, which spans 1874 through 1988.
