Our Watersheds
A watershed is an area of land that catches rain or snow and drains it into the same location. Every drop of water that falls on parks, farms, forests, parking lots, and even your front lawn is channeled into soil, groundwater, creeks, and streams. Eventually this water makes its way to rivers, lakes, and finally the ocean.
What we do on land affects our water! Sweet Water works with stakeholders to resolve the following threats to our waterways:
NONPOINT SOURCE POLLUTION
According to US EPA, NPS pollution is the leading cause of water quality issues in the United States. It includes urban runoff (chemicals, oils, construction sediment), residential runoff (road salt, fertilizers/pesticides from yards/gardens), & agricultural runoff (fertilizer, manure, etc).
POINT SOURCE POLLUTION
Point source pollution is defined by the US EPA as "any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack." Common types of point source pollution include factories, sewage treatment plants, concentrated animal feeding operations (CAFOs), & paper mills. Point sources must obtain permits from the state & US EPA to discharge into waterways.
PHYSICAL IMPAIRMENTS
Physical impairments refer to physical obstructions or alterations to a waterway that negatively impact water quality. Such impairments include dams, channelization, and other impediments to water flow and fish passage.
Sweet Water works in every major watershed throughout Southeastern Wisconsin. These include the Milwaukee, Menomonee, Kinnickinnic, Root, and Oak Creek, as well as Lake Michigan and Milwaukee's Inner Harbor.
