Big Muddy Clean Sweep 2021

To celebrate our 20th anniversary, Missouri River Relief is launching a 2-month long rolling cleanup program covering nearly 200 miles of remote, never before cleaned river!

The stretch of river from Kansas City to Columbia, MO covers nearly 200 river miles. This stretch of river is remote, but is no stranger to trash and waste from upstream cities and farmland. Many of these areas have never been cleaned before. These stretches of river suffer from a myriad of pollution from waste tires, white goods, hazardous material and non-point pollution from illegally and improperly disposed of trash. Forty-three percent of Missourians receive their drinking water from the Missouri River and we aim to make this a healthier resource for everyone.

Throughout this program we will reach out and work with members of the river communities we visit, engaging families, students and civic groups in stewardship. Armed with the tools, equipment, volunteers and river knowledge, we will make a huge impact on the health of the Missouri River and the communities we engage. We will also work with media contacts to inform the public of our work, and the sponsors and supporters who made this program possible.

We intend on working with over 400 volunteers and removing 20 tons of trash over the course of the 2 month cleanup!

We will keep an updated schedule and results of events here!

Volunteer Information

What we're doing

Volunteers will arrive at their cleanup headquarters at 9:00 AM for registration. After registration, volunteers will receive a brief orientation and safety talk and will be fitted for life jackets. Volunteers will then board our boats operated by Missouri River Relief staff and will be taken to cleanup locations along the banks of the Missouri River. Volunteers will work in teams to remove illegally and improperly disposed of trash and flood debris from the banks for several hours before returning to the boat ramp around noon.

What to bring

Dress in layers for changing weather conditions and prepare for cold or hot weather depending on the time of year. We will be there rain or shine! Wear work-appropriate clothing. Long pants are strongly recommended. Sturdy shoes or boots are required; no flip-flops or open-toed shoes are allowed on boats. Bring sunscreen, bug spray, water bottle and snacks to tide you over until lunch. Always expect muddy conditions.

What you get

Volunteers will receive a free Big Muddy boat ride, cool t-shirt, trash bags, gloves, life jackets, and a reusable water bottle. We will have snacks available when you get back to the boat ramp from 11:30 - 12:30.
