Here’s the latest from the city about the closure of Newton’s Crystal Lake.

Crystal Lake to Remain Closed Until Further Notice

Newton – Due to recent water quality test results, Crystal Lake will remain closed until further notice. The lake has been closed since Monday, due to low visibility levels resulting from a recent algae bloom. On Monday, water samples were collected and tested for bacteria and toxin levels. Today, the City of Newton received the
results from the Massachusetts Department of Public Health (MDPH,) which showed elevated levels of cyanobacteria (blue-green algae.) Although toxins were not detected, bacteria levels exceed those recommended by MDPH for water contact. Individuals as well as pets are advised to avoid any contact with Crystal Lake at this time.

“The type of algae bloom we are seeing at Crystal Lake is common, though it occurred earlier than usual this year due to the warm weather trend,” said Linda Walsh, Director of Health and Human Services. “Public safety is our highest priority, which is why we have taken this precautionary measure, and are asking people and pets to avoid contact with the water at Crystal Lake until further notice.”

Because toxins have not been detected, health effects are minimal for individuals who may have utilized the lake recently. Regular monitoring will continue in accordance with state guidelines.
