Our watershed: Learning more 

What is a watershed? 

TheMinnesota Pollution Control Agency(MPCA) states that a watershed is: “the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake.” 

Reducing pollution in our watershed

In November, the Landscape and Environmental Design (LED) Committee met with staff from the Ramsey County Parks and Recreation Department and the Capitol Region Watershed District. These agencies offer technical assistance for implementing landscaping techniques that reduce the flow of pollutants into our waterways. CTC belongs to the Capitol Region Watershed District (CRWD). All water found in the Capitol Region Watershed District (which includes wetlands, creeks, and lakes) eventually drains into the Mississippi River

One of the things we learned about was stormwater pollution, the idea that the “materials washed off the hard surfaces in our towns and cities eventually end up in the water, where they can become harmful pollutants.” When it rains or the snow melts, the water picks up pollutants on our hard surfaces and flows into our storm drains.

Leaves on the ground that haven’t been swept off the street can also end up in our waterways. Leaf litter and fertilizer can bring too many nutrients (like phosphorous) into surface water such as lakes, which leads to excess algae growth. 

During our meeting, we learned that rain gardens are one stormwater management technique used to reduce stormwater pollution.

However, the substances that do end up in our waterways can negatively impact water quality. Keep reading LED’s Terrace Times articles in the upcoming months to learn more about how we can help reduce the pollutants going into our waterways.
