What is a Watershed?What is a Watershed?

• A watershed is a system.

• It is the land area from which water, sediment, and dissolved materials drain to a common point along a stream, wetland, lake or river.

• For each watershed, there is a drainage system that conveys rainfall to its outlet.

• Its boundaries are marked by the highest points of land around the waterbody.

Dissolved Oxygen

• not lower than 4 with an average of at least 5 mg/L or ppm

Higher DO in the winter months
