Stormwater ponds capture the stormwater runoff from the surrounding area, along with many of the pollutants like excess nutrients found in fertilizers, pet waste, and yard debris.
Aquatic plants in the littoral zone can improve water quality by removing excess nutrients like phosphorus and nitrogen from stormwater runoff. The plants then use these nutrients to grow and remain healthy. This can help improve water clarity and prevent algal blooms. These native plants also stabilize the banks to prevent erosion and provide habitat for wildlife.
