Watershed Sanitary Survey
The quality of water stored in our reservoirs can be negatively affected by residential and commercial development and human activities in the watersheds. A Watershed Sanitary Survey examines the potential sources of contaminants in the watersheds draining into the reservoirs, and includes recommendations for managing these effects. The Watershed Sanitary Survey is updated every five years.
