Join the Confluence Conservation Crew

Volunteers are needed to help at events such as Earth Day, National Public Lands Day, Mission:Clean Stream, Confluence Trash Bash and Race for the Rivers. Service days will be held at many sites, including Riverlands in West Alton, Riverwoods in Bridgeton and many local parks near you.

Crew members are asked to pledge to support  three service events  this summer.  Members will receive gloves, a water bottle , and a t-shirt at their first volunteer event. 

Crew leaders are needed to help coordinate service projects.  Pledge to support five volunteer events and you are eligible to be a crew leader and receive special recognition.

Single day volunteers are welcome too and make up the majority of our volunteers! The work is sometime rewarding and enjoyable and sometime wet and muddy, but always worthwhile. To register for the monthly trail maintenance/clean-up at Riverlands, click here.

Greenway will be assisting our friends at the Mississippi River Water Trail Association with

 The Firecracker Race,

the Mississippi Challenge

on the 4th of July

The race will occur on the Mississippi River Alton Pool formed by the Mel Price Lock and Dam, located upriver from the city of Saint Louis at the Lincoln Shield access. This section of the Mississippi River is very much like a large lake and the race will occur in an off-channel portion of the river. Racers will navigate a triangular 3 mile loop.
