Mission Clean Stream

Mission Clean Stream

As you are out and about in early April, you may notice green and red mesh bags along the roadways, in the parks and along the rivers and streams in St Charles County. These will be gathered by the hundreds of families, scout and church groups and other volunteers who scour the county to clean up trash. Every bit of trash picked up by these super heroes is a bit of trash that doesn’t make its way into our rivers and streams. Trash in our waterways is more than just unsightly. It pollutes our drinking water and destroys the natural habitat of plants and animals that rely on clean, fresh water just like we do.

2022 marks the 20th anniversary of Mission: Clean Stream in St Charles County. Over the past 20 years, thousands of volunteers have picked up an average of 10 tons of trash each year. Historic dumping sites have been cleared of tons of metal and hundreds of tires. Our amazing volunteers and dedicated city and county employees have made our county a better place.

Check out this video if you want to know more about what is involved in cleaning up a stream.

This year we will be gathering on April 2 at locations across the county in order to keep up the good work. Register by March 25 to receive a special 20th Anniversary T-shirt. Bags will be provided. Be sure to dress for the weather. Wear sturdy shoes or boots. Bring a water bottle. Bring gloves.

Each site has individual registration and rendezvous locations. Times may vary so follow the instructions provided when you register. Most places have sites that are accessible to those with limited mobility and for smaller children.
