Reservoir Description

E. V. Spence Reservoir is a 14,950-acre reservoir located on the Colorado River near Robert Lee, Coke County, Texas. It has a history of prolonged water level declines and has never filled to conservation pool. Golden alga Prymnesium parvum blooms caused substantial fish kills in the 2000’s that effectively eliminated the fish community. Subsequently, low and moderate toxic conditions have been recorded on an annual basis.

Management History

The management of this reservoir has been impacted by chronic toxic golden alga blooms since 2001 and persistent low water levels. Florida strain Largemouth Bass, White Crappie, White bass, Bluegill, and Blue Catfish were stocked in years following significant water level rises in 2015 and 2018.
