Learn what you can do to help protect and improve the wonderful resources in these watersheds. Learn about the Two Rivers Coalition, Inc., a citizen based group working to protect the health of the Black River and Paw Paw River Watersheds through conservation, education, and advocacy.

Our goal is to be your source of information about the Black and Paw Paw River Watersheds here in Southwest Michigan.  We hope our web site will provide you with accurate and thought provoking information about these watersheds and the community we live in.  We believe that an informed and engaged community is the key to making this one of the best places to live and play. Please look around and let us know if there is information that you would like for us to include on our web site. Looking for a specific topic?  Try Search at the top of the page.

The Black and Paw Paw Rivers drain lands in Allegan, Berrien, Kalamazoo and Van Buren Counties.  The Black River flows into Lake Michigan at South Haven.  In Benton Harbor, the Paw Paw River flows into the St. Joseph River which then flows a short distance to Lake Michigan.  Some say that the St. Joseph River is actually the Great South Branch of the Paw Paw River.


How will Climate Change Affect              Southwest Michigan?

Attendees of the TRC 10th Annual Meeting on November 8, 2018 were treated to a highly informative and persuasive presentation by Dr. David Karowe of WMU. He explained the scientific evidence which absolutely establishes the dominant role humans are playing in the warming of the planet. He went on to explain what life will be like in the Great Lakes by the end of this century under two scenarios: business as usual (do nothing) or return to the Paris Climate Agreement. There will be rising summer and winter temps, earlier and more severe spring floods, more frequent and more intense rain events, and more severe late summer droughts. We could lose iconic tree species like White Pine and Sugar Maple. Bottom line is that if we do nothing different, by the end of the century we will not recognize the place we call Michigan. But, if we act quickly, we can still choose the type of planet we leave to future generations.

July 28, 2019 - Prairie Fen Paddle/Hike Trip

Co-sponsored with Michigan Nature Association

9:00am to Noon and 1:00pm to 4:00pm

Two Rivers Coalition’s - Prairie Fen Paddle Trip Sunday, July 28th , Trip 1: 9:00 AM-12:00 PM, Trip 2: 1:00 PM to 4:00 PM Come explore the flora and fauna of two prairie fens along the shores of Paw Paw Lake in Kalamazoo County. We will launch from the DNR public boat ramp off of Paw Paw Lake Drive and paddle the clear, placid Paw Paw Lake waters exploring the aquatic and shoreline vegetation as we make our way to two Michigan Nature Association (MNA) Sanctuaries. Both sanctuaries protect valuable prairie fen habitat in the headwaters of the East Branch of the Paw Paw River. The Palmer Sanctuary protects 22 acres along the east shore of the lake while the smaller Wilkie Sanctuary protects 3 acres of a larger 30 acre wetland complex along the northern edge of the lake. We will stop at each sanctuary and wander its wet sedge meadows, marl flats and mucky emergent habitats seeking out late summer flora and fauna. If time and conditions permit, we will paddle the open lake enjoying a summer day on one of the Paw Paw River Watersheds beautiful and lesser known lakes. Participation will be limited to minimize impact to the critical prairie fen habitat. To protect the rare flora and fauna these sanctuaries are not accessible to the public without MNA permission.

RSVP REQUIRED! Contact to sign up: Kevin Haight: 269-408-6262, email:

Directions- use hyperlink to open map to the launch site: DNR Public Boat Ramp Details

Other Details: - Bring a canoe, kayak or SUP along with a pfd. Boats are available for loan if you do not have one, but must be reserved in advance. - Bring sun protection, snacks and ample water for up to 4 hours of late summer exploring. - We will be hiking in wet (standing water), mucky soil with tall vegetation. Long, light weight pants tucked in water proof muck boots are ideal to protect the lower body. - If it is a hot summer day, a quick swim may be an irresistible way to finish off the trip.


Paddle with a Naturalist on the Paw Paw River

Saturday August 10th

Watervliet to Coloma

Come and join TRC for an easy float down a picturesque segment of the Paw Paw River accompanied by a naturalist guide. This is a great opportunity to learn about the floodplain ecosystem and the invasive species threats it faces. This paddle is co-sponsored by Cooperative Invasive Species Management Area SW x SW Corner.

Meet at the new Paw Paw River County Park (south bank of river in Watervliet) at 10:00 a.m. to drop off boats, stage vehicles downstream at Coloma Public Works access, and then carpool back to launch site. There is a universal access slide in launch facility at the county park but none at the Coloma take-out. There will be a short introduction to aquatic invasive species by the naturalist and we will try to be on the water by approximately 11:00 a.m. This is normally a 90 minute to 2 hour plus float.

Bring your own boat and PFD (wearing your PFD is required to be part of our group).

A limited number of loaner kayaks, paddles, and PFD's are available free of charge but MUST be reserved in advance by emailing Kenneth:

Or Why Two Rivers Coalition is Calling for the Shutdown of Line 5 under the Straits of Mackinac

At its July meeting, the TRC Board of Directors passed a resolution calling for the immediate shutdown of Line 5 which carries crude oil products under the Straits of Mackinac. My job is not to convince anyone of the correctness of this decision, but rather, to explain why we felt it was an appropriate action for a local environmental group to take. Remember, the mission of TRC is to…”protect the health of the Black River and Paw Paw River watersheds through conservation, education, and advocacy.” As a water quality organization, we believe it is just not enough to work to protect the water only until it runs into Lake Michigan.

Two Rivers Coalition Resolution Calling for Shutdown of Line 5 under the Straits of Mackinac


Because of Two Rivers Coalition’s paramount interest in protecting the waters of the State of Michigan and the entire Great Lakes Basin to which the Paw Paw River and Black River flow, and because the potential risk to those waters from a spill or leak from the sixty-four year old Line 5 pipelines under the Straits of Mackinac is potentially catastrophic in terms of both environmental and economic damage, and because the risks of such a catastrophe far outweigh any short-term benefits to the people of the State of Michigan from continued transportation of crude oil products through Line 5,

THEREFORE, Two Rivers Coalition calls upon elected state and federal governmental representatives and relevant regulatory entities to immediately shut down Line 5.

Hydraulic Fracturing or "Fracking" - TRC"s Endorsement to Ban in Michigan


Motion - August 12, 2015 Board Meeting:  TRC officially endorses petition to ban fracking in Michigan because of potential threat to ground water and surface water resources in Michigan. 

The ballot summary on the circulating petition is:[8]


An initiation of legislation to prohibit the use of horizontal hydraulic fracturing or “fracking” and acid completion treatments of horizontal gas and oil wells; to prohibit emission, production, storage, disposal, and processing of frack and acidizing wastes created by gas and oil well operations; to eliminate the state’s policy favoring ultimate recovery of maximum production of oil and gas; to protect water resources, land, air, climate, and public health; and to allow residents to enforce the provisions of this ballot language, by amending Public Act 451 of 1994 entitled “Natural Resources and Environmental Protection Act,” by amending section 61528, 61529 and 61530.[9]



Anti-fracking ballot effort fails to collect enough signatures, seeks more volunteers (link to article)
