Reservoir Description

Marble Falls Reservoir is a 573-acre (when full) mainstem stable-level impoundment of the Colorado River, located in the City of Marble Falls, Burnet County, TX. It was constructed in 1951 by the Lower Colorado River Authority (LCRA) for hydroelectric power, recreation and water supply. The reservoir is riverine in nature with a limited number of coves and creeks. The reservoir area represents a geological transition between granite outcroppings and limestone formations of the Edwards Plateau, and its shoreline length is 18.7 miles. Most of the shoreline is private; three public boat ramps are available.

Management History

Important sport fish include Largemouth Bass and Channel Catfish. Florida Largemouth Bass were stocked in Marble Falls Reservoir in 1999 to increase Florida Largemouth Bass genetic introgression. Channel Catfish were last stocked in 2016. The lake is managed under statewide regulations. Marble Falls Reservoir has historically had very low aquatic vegetation coverage. In 2013, non-native species were recorded (hydrilla and Eurasian watermilfoil). Since hydrilla can become an operational issue for the LCRA, an herbicide treatment plan was implemented in 2013 for the eradication/control of hydrilla.
