Water Quality

graph showing phosphorus levels in Mirror Lake over time
Mirror Lake’s higher phosphorus levels indicate poorer water quality.

Water quality of Mirror Lake is poor, measurements for phosphorus, chlorophyll-a, and water clarity failed to meet the state standards for shallow lakes. Mirror Lake experiences frequent algal blooms as a result of excess nutrients coming into it from the surrounding watershed and curly-leaf pondweed. The blue-green algae in these algal blooms can pose health risks for lake users and pets because of the potential for algal toxins to form.
There is also limited plant diversity in Mirror Lake. During the 2019 plant survey, only two plant species were catalogued—both of them were invasive species.

Current Studies

Currently, the District is undertaking a lake water quality study to identify potential water quality improvement projects to help improve the overall health of Mirror Lake. The study will be completed in 2023.
