Water Quality Testing

Annually Northeast Aquatic Research provides Water Quality Reports from the data the Crystal Lake Association Water Quality Team collects from April to November. Samples of water are collected at intervals for the measurements of Dissolved Oxygen, phosphorus and water temperature. The clarity of the water is taken from the surface using a Secchi scope.
As of 2019: The Water Quality Annual reports will now be combined with the Milfoil reports .
