Stormwater Education

Stormwater is the largest source of pollution in Montana’s waterways. You can help change that!

What is stormwater?

Stormwater is water from rain or snow that runs over land, streets, parking lots, and rooftops. This water picks up trash chemicals, and other pollutants as it flows into surface water like creeks and streams. The water in our storm drains is not treated before it empties into our streams, making it important to have only rain down the drain!

Social Media Campaign

Follow along on our Facebook and Instagram to see tips on how we can reduce stormwater pollution. Don’t forget to share our posts with friends so they can learn how to reduce stormwater pollution as well!

Want to tell us what you’re doing to minimize stormwater pollution? Share your story with us by tagging @cfwep and #CFWEPEarthMonth!

Safe Stormwater PSA Competition

Public Service Announcements (PSAs) help inform the public on how we can help protect our streams from stormwater pollution. The best PSAs come from YOU! 

Our Safe Stormwater Public Service Announcement Competition runs April 22-May 22 with winners announced on May 31. Find more information below or by downloading a brochure.


When walking your furry friend, always pick up waste. Harmful bacteria from pet waste washes to our streams along with increased nitrate, which results in less oxygen for our fish.

Only dispose of RV waste at properly designated dump stations that safely store the waste. Never empty RV waste into storm drains, which empty untreated into our local streams. 

Bag and collect all yard clippings or compost them appropriately. Yard clippings can clog storm drains and the excess nutrients they contain can impact the health of our streams.

Use a local car wash (which is already equipped to deal with stormwater) or wash cars on your lawn to keep potentially harmful chemicals from washing into our storm drains.

Never pour anything down storm drains, which empty into our streams. Instead of dumping, take your waste to the local landfill. They accept antifreeze, vehicle batteries, metals, oil, and yard waste.

Research risks of chemicals that you apply to your lawn to learn about potential. Avoid applying chemicals before rain to reduce the amount of chemicals that runoff your lawn.

Safe Stormwater Public Service Announcement Competition


Our PSA competition is open to to K-12 students in the Clark Fork and Blackfoot Watersheds.


Submissions accepted from Earth Day, April 22, 2022 until Sunday, May 22, 2022 at 5:00 PM. Winners will be announced on Tuesday, May 31, 2022


Create your PSAs using technology you already have. Download our PSA information and technical guide to learn how you can make your best PSA. PSAs can be video (for TV), audio (for radio), or posters (for print).

PSA Competition Guidelines


PSAs inform communities about issues relevant to them! Stormwater pollution is a major threat to our streams, and your PSA could help people learn how they can reduce the pollution they create.
