Watersheds

Lake water quality is influenced by runoff from all upland areas that flow toward a lake’s lower elevation. This drainage area is known as a watershed. Unique features of watersheds include their topography, soil fertility and erodibility, vegetation and hydrology which directly effect runoff and the lake’s natural condition.

• Rapid Watershed Assessments
  Rapid watershed assessments provide initial estimates of where conservation investments would best address the concerns of landowners, conservation districts, and other community organizations and stakeholders. These assessments help land-owners and local leaders set priorities and determine the best actions to achieve their goals.
