Watershed sediment yield reduction through soil conservation in a West-Central Oklahoma watershed
Soil conservation practices on the Fort Cobb Reservoir watershed in West-Central Oklahoma were limited before the 1950s. However, extensive soil conservation measures were implemented in the second half of the 20th century to protect agriculturally fertile but erosion-prone soils. Fortuitously, the U.S. Geological Survey (USGS) collected instantaneous suspended-sediment and discharge measurements on major tributaries within the watershed in 1943 –1948 and again in 2004 – 2007, called pre- and post-conservation periods respectively.
