Welcome to Two Rivers Coalition

Explore and discover with us, the Black River and Paw Paw River Watersheds! Learn how you can help protect and improve these wonderful watershed resources.

We believe an informed and engaged community is key to protecting these watersheds, their biodiversity and their positive impacts to our quality of life in Southwest Michigan. Take some time and wander around our website and get to know the Black River and Paw Paw River watersheds and the work we are doing to conserve, educate and advocate for them. Spotlighted work in the watershed is listed below our watershed activity map. 


 

 

Spotlighting Work in the Watersheds


Ox Creek Watershed Project:

Check out the great work being done by SWMPC, Sarett and others near Benton Harbor to restore a degraded urban creek. Ox Creek is a sub watershed of the Paw Paw River that is at the confluence of the Paw Paw River and St. Joe River. Ox Creek empties into the Paw Paw River just upstream of the confluence of the Paw Paw and St Joe Rivers.

Prothonotary Warbler Partnership (enters its 4th year in 2024)

We are still figuring out what we need to do to get the warblers to accept our nest boxes. In 2023 we had our first successful nesting in one of our nest boxes!

 

We are planning for a June paddle trip (see calendar for details) to see the nesting warblers and enjoy some time on the water.

 

We are asking volunteers to use EBird and record sightings of the prothonotary warblers in our watersheds. This data will help us understand their distribution in our watersheds and help indicate where the best floodplain forest exists. Check out our web page for more information.

Volunteer Stream Monitoring:

Stream monitoring is one of the most rewarding and fun community science projects TRC takes part in each year in partnership with VanBuren Conservation District.

There is nothing like getting into the water and/or picking out the aquatic insects captured to really learn about our waterways. We have been collecting data since 2015 and follow the protocols developed by MiCorps which are used across the state to monitor the health of our waterways. Check out the VBCD Story Map to learn more.

Join us as we play in our waterways while adding community science data that is used to measure our rivers health. My Calendar – Van Buren Conservation District (vanburencd.org)

E.Coli Monitoring: 2023 Update:

The Black River Watershed (BRW) drains 287 square miles of Van Buren and Allegan counties before emptying into Lake Michigan at South Haven. The project goals were to determine the source of consistently high levels of E. coli in the BRW measured by Two Rivers Coalition (TRC) since 2017 and determine whether the source was primarily human, cow, or a combination. 

The 2022 data was still unconclusive but points to an issue with E.coli in our watersheds. A Fact Sheet summarizing the findings was completed.
