Fish populations in E. V. Spence Reservoir were surveyed with electrofishing in 2015 and with gill netting 2016. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

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 winters of 2001, 2002, and 2003 that effectively eliminated the fish community. Subsequently, 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 low water level. Florida-strain Largemouth Bass, Striped Bass, Bluegill and Channel Catfish were stocked in multiple years following major fish kills due to toxic golden alga blooms. These stockings failed to produce a viable fishery. No stocking has been conducted since 2008.

Management Strategies

Continue to manage under statewide harvest regulations. Continue to monitor for gold alga during winter months. Conduct additional electrofishing surveys in 2017 and gill net surveys in 2018. Conduct general required monitoring with electrofishing in 2019 and with gill netting in 2020.
