Stormwater runoff is considered the largest source of pollution in the Highland Lakes. This is not surprising, since the U.S. Environmental Protection Agency (EPA) reports that pollution in stormwater runoff accounts for more than 98 percent of the fecal and total coliform bacteria, 90 percent of the sediment, 80 percent of the nitrogen, and more than half of the phosphorus entering the nations rivers and streams.
The impacts of stormwater runoff can be widespread and severe, including:
- Siltation of creeks and reservoirs.
- Reduced fish and wildlife habitat.
- Increased growth of aquatic weeds.
- Algal blooms and fish kills.
- Reduced recreational opportunities because of bacterial contamination and increased turbidity.
- Contamination of food and water sources.
Benefits of managing pollution
Management of pollution caused in stormwater runoff is far less expensive than correcting it after it has occurred. The benefits of managing stormwater runoff pollution include:
- Expanded recreational and tourism opportunities — and economic growth.
- Increased property values and tax base along the river, lakes and tributaries.
- Increased productivity of range and farmland, as well as aquatic ecosystems.
- Reduced water treatment costs.
- Preservation of diverse wildlife habitat.
- Prolonged viability of water storage reservoirs.
