Lake Condition Updates

July 31, 2020
Test results taken in June indicated Emerald Cove was in the Warning Level (second advisory level, orange signs). EVMWD took water samples at that location on July 16, and the results have indicated that Emerald Cove has returned to the Caution Level (first advisory level, yellow signs). The orange warning signs have now been removed.

Canyon Lake Algal Blooms

As with any lake, ocean, or river in the nation, Canyon Lake’s aquatic ecosystem cannot be compared to a swimming pool that is treated with chemicals to ensure water quality.  If you choose to use the lake for swimming, keep in mind that natural lake processes occur and there may be times that the water quality for recreation may pose a health risk.
