Soil and silt in the water increase water temperature and murkiness, which harm fish and their food supply.
Storm water collects, mixes and drains exposed material on the surface such as litter, trash, dirt, metals, oil, pesticides, herbicides, fertilizers, paint, and other illicit discharges/improper disposals. Since storm water is not treated, these pollutants are directly discharged to our creeks, rivers, and other bodies of water.
