​Fertilizer Impact on Third and Druce Lakes

The use of phosphorous containing fertilizers on our lawns can have a negative impact on our neighborhood retention ponds and our lakes. Stormwater runoff from neighborhood yards, driveways, and streets flow to the street storm sewer drainage system which discharges into the neighborhood retention pond and eventually to Druce and Third lakes. The phosphorous contained in the runoff can contribute to algae blooms in our ponds. These algae blooms can enter our lakes creating unhealthy conditions for swimming, boating, and fishing. Phosphorous also contributes to excess vegetation growth in our ponds and lakes, especially invasive plants. Please refrain from using fertilizers containing phosphorous on your lawns. Please see the links below for articles regarding phosphorous use:
