Big Muddy Speaker Series presents:
Missouri Stream Teams - 29 Years Watching our Waters


The Missouri Stream Team Program brings together government resources and expertise with citizen passion and dedication to protect and improve the public waters of our state. From river clean-ups and stream restoration to water quality monitoring and education (and more!), Missouri Stream Teams are a model for citizen involvement nationwide.
This panel discussion will bring together some of our statewide water conservation leaders to discuss some of the innovative work Stream Teams are doing in our city and across the state. We'll be joined by Mary Culler, Executive Director for Stream Teams United; and Steve Nagel, former Director of the River Des Peres Watershed Coalition.
Please come join us for an evening of discussions on our state's watersheds with some of our state's leaders.
Meet Your Presenters

They also organize the 100 mile Paddle MO adventure on the Missouri River. Mary was previously one of the Our Missouri Waters coordinators with the Department of Natural Resources, a watershed program that was defunded by the current administration.
