Studies have shown that nonpoint sources of pollution contribute most of the contaminants found in our surface waters. Lake Protection Through Watershed Management Runoff in the watershed carries pollutants to its lakes and rivers. The best way to reduce pollutants in a lake is to minimize them in the watershed. Sound land management limits or prevents pollutants from reaching lakes and rivers. The management techniques employed depend on the particular land uses within the watershed.
Watershed surveys can identify current and potential pollutants and their sources.
With this information, a watershed community can take steps to prevent or reduce pollution. As an individual, you can help your lake by reducing your use of products containing phosphates and other pollutants, limiting land clearing, reducing lawn size and maintaining good plant cover. Vegetation near lakes and rivers helps prevent fast-flowing runoff from polluting your lake. Involving your friends and neighbors increases the positive impacts of good management. The New Hampshire Lakes Association is working to build awareness of the importance of watersheds and their effects on water quality.
