Environmental Impact

These controlled releases help maintain downstream ecosystems, support aquatic life, and provide environmental flows for the Colorado River ecosystem.

Additional Information

What are Outflows?

Lake Travis outflows are controlled water releases from Mansfield Dam managed by LCRA. These releases serve multiple purposes including flood control, hydroelectric power generation, water supply for downstream users, and maintaining environmental flows in the Colorado River.

Hydroelectric Generation

Water releases generate clean electricity through turbines at Mansfield Dam, contributing to the regional power grid with renewable energy.

Water Supply

Controlled releases provide water for municipal use, agriculture, and industrial operations in communities downstream from Lake Travis.

Environmental Flows

Releases maintain healthy river ecosystems downstream, supporting fish populations, riparian vegetation, and overall biodiversity in the Colorado River basin.
