Fish populations in Eagle Mountain Reservoir were surveyed in 2024 using trap nets and electrofishing, and in 2025 using gill nets. Historical data are presented with the 2024-2025 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Eagle Mountain Reservoir is an 8,504-acre impoundment constructed on the West Fork Trinity River by the Tarrant Regional Water District (TRWD) in 1932 for municipal and industrial purposes. The reservoir is located in northwest Fort Worth, is approximately 10 miles long and 3.5 miles wide (widest point), drains 1,970 square miles of watershed, and has 93.5 miles of shoreline. Conservation pool elevation is 649 feet above mean-sea-level resulting in a storage capacity at conservation pool of 179,880 acre-feet. Water level remained near conservation pool from 2015 through 2021. Boat access is good but shoreline angling access is limited. There is one ADA compliant fishing pier on the reservoir. Fishery habitat consisted primarily of natural banks, rocky shorelines, and boat docks. Eagle Mountain was deemed as infested with Zebra Mussels in 2016.

Management History

Important sport fishes include Largemouth Bass, crappies, White Bass, and Blue Catfish. All species are managed with statewide regulations. Lone Star Bass were stocked in 2025.

Fish Community

• Prey species: Gizzard and Threadfin Shad were in high relative abundance in the reservoir. Bluegill and Longear Sunfish are also available as prey. Some Bluegill over 6 inches are available for anglers.
• Catfishes: Blue Catfish relative abundance remained high and produced some large individuals. The relative abundance of Channel Catfish was variable during the past three surveys but remained low. Although present, no Flathead Catfish were sampled during 2025 gill netting..
• White Bass: White Bass catch rates remained relatively stable compared to the two previous surveys.
• Black basses: The Spotted Bass catch rate increased since the previous survey. The Largemouth Bass population increased in abundance since the last survey. Two legacy class fish have been donated since the previous report including a new waterbody record of 16.00 pounds in February of 2022..
• Crappies: The relative abundance of crappies decreased since the 2022 survey. The majority of the crappies sampled were under 10 inches in length.

Management Strategies

Monitor zebra mussels in Eagle Mountain Reservoir. Conduct a year-long, annual creel survey in 2027/2028 to assess angling effort and catch statistics for Eagle Mountain Reservoir to compare to 2016/2017 results. General monitoring with gill netting, trap netting, and electrofishing will be conducted in 2024-2025.
