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.
