All water bodies age in a natural process where sediment, organic
matter, and debris gradually fill in the basin forming a marsh or delta.
This on-going process occurs gradually over many years.
When land in the drainage area of a lake is disturbed by rural or
urban development, the aging process is greatly accelerated.
Non-point source pollution is a general term used for describing a
foreign substance entering the water body. Typically, pollutants- silt,
nutrients, pesticides, etc. carried into the water body via storm water
runoff.
The most widespread component of non-point source pollution is
sedimentation caused by eroding soils in the watershed. Soil
erosion cannot be stopped, only slowed by effective control
techniques and sound management practices in the watershed.
