Temperatures and other factors in late summer and early fall combined with low flow releases can create conditions favorable for blue-green algae to develop. Such seasonal occurrences are marked by strong hydrogen sulfide odors and algae blooms. While a potential algae bloom in the area below Canyon Reservoir Dam has been reported, the Guadalupe-Blanco River Authority wants to provide assurances that the water treatment processes of public water systems ensure safe drinking water. GBRA staff has taken water samples from the reported area for analysis. When results of those analyses are available, GBRA will provide an update. In the interim, individuals should exercise caution around areas of rivers or creeks with stagnant water, as it can increase the chance for harmful contact. Pets also should be kept on leashes and not allowed to drink from stagnant water areas.

GBRA Communications and Education staff disseminates press releases to local media and posts accordingly on the press release page of GBRA’s website:  Information also is shared on GBRA’s social media accounts through Instagram and Twitter “@GBRATX” and Facebook at “GBRA of Texas.”

The GBRA was established by the Texas Legislature in 1933 as a water conservation and reclamation district. GBRA provides stewardship for the water resources in its 10-county statutory district, which begins near the headwaters of the Guadalupe and Blanco rivers, ends at San Antonio Bay, and includes Kendall, Comal, Hays, Caldwell, Guadalupe, Gonzales, DeWitt, Victoria, Calhoun, and Refugio counties.
