This is the authors' summary from a 20-page report. For a copy of the complete report, use the download link in the sidebar.

E.V. Spence Reservoir was surveyed in 2003 using trap nets and electrofishing and in 2004 using gill nets. 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 located on the Colorado River near Robert Lee, Coke County, Texas, and is used for water supply and recreation. E.V. Spence has a history of prolonged water level declines and has never filled to conservation pool. At the time of sampling, the reservoir covered approximately 2,700 acres and it has become increasingly more saline since construction. Also, in the winters of 2001, 2002, and 2003 golden algae Prymnesium parvum blooms caused major fish kills in the reservoir. Boat access is restricted to a single one-lane temporary ramp and shoreline access is adequate.

Management Strategies

Based on the current information, the reservoir should continue to be managed with the existing regulations. Golden algae blooms in 2001, 2002, and 2003 essentially eliminated the fishery at E.V. Spence Reservoir. The reservoir should be re-stocked with forage and game fish species that were present prior to the fish kills. In addition, cell densities and toxicity levels of golden algae within E.V. Spence Reservoir should be monitored and the reservoir should be stocked when conditions are favorable for fish survival. Since the fishery and angler use is essentially non-existent on E.V. Spence Reservoir, the annual 9 day spring quarter creel survey will be removed from the four year sampling schedule and the annual gill net survey will be reduced to once every two years.
