Highland Lakes Water Quality

The LCRA provides routine updates regarding water quality and the many programs related to the maintenance of the Colorado River and Highland Lakes.  Additional information regarding water quality and protection programs can be found at the LCRA Website – Protecting Water Quality.

Fresh Water Algae

 These updates include routine monitoring test results and data related to the status of blue-green algae identified in the Highland Lakes last year.  Although freshwater algae play a vital role in maintaining the health of the aquatic ecosystem in our lakes this particular alga (blue-green) can at times produce toxins that are dangerous to animals and people.

Routine monitoring along the shorelines in lakes Buchanan, Inks, LBJ, Marble Falls, and Travis has not detected any algal toxicity recently however, residents should remain mindful of its possible presence.

 People and pets can be exposed to harmful algae toxins through direct skin contact from swimming and other recreational activities or ingesting water or food contaminated with harmful algae toxins in the lake. 

Horseshoe Bay’s drinking water is treated and tested by utility operators to remove harmful algae toxins to acceptable federal regulatory guideline limits for public water supply uses.

The LCRA is continuing to conduct tests on water and algae throughout the Highland Lakes and recommends treating all algae as if it could be toxic, and to avoid contact with algae in any of the Highland Lakes.  Seek veterinarian help immediately if your pet becomes ill after contact with a natural water body.
