Great Rivers Habitat Alliance

Great Rivers Habitat Alliance A group of citizens, concerned about the current flood plain development trends within the St. Charles County.

Great Rivers Habitat Alliance (GRHA) was founded in 2000 in order to protect the 100 year Confluence floodplain for the benefit of wildlife, historic waterfowling, agriculture, clean water and people. Louis Metropolitan region, established Great Rivers Habitat Alliance in June 2000. GRHA addresses issues affecting wetland habitat and promotes sensible use of flood plains in the confluence region o

f the Mississippi, Missouri, and Illinois Rivers. Great Rivers Habitat Alliance supports preservation of the flood plains of the Mississippi and Missouri Rivers. The organization’s primary focus is on the Confluence Flood Plain in St. The organization seeks to save our natural flood plain and rural agricultural heritage. GRHA strives in influencing public officials to make changes in their policies and legislation that is affecting the regional flood plain development. Since its establishment, GRHA has made contacts with regional influential politicians and officials and begun an awareness campaign to inform the general public about flood plain developments and new levee construction efforts that typically closely follow new flood plain developments. These awareness campaigns are the initial tools intended to raise attention about the importance of saving flood plains as natural water storage areas, instead of converting it into building sites for new, larger, strip malls and shopping centers. In order to effectively conduct and fund awareness campaigns and other efforts, the IRS approved GRHA as a charitable 501c3 organization status in Fall 2000. GRHA has also formed partnerships with other environmental organizations such as Missouri Coalition for the Environment, Missouri Department of Natural Resources, and Ducks Unlimited, etc. to effectively work on flood plain protection efforts. One of GRHA’s future goals is to acquire one or more conservation easements within the regional flood plain during 2001. The ultimate preservation goal is to protect 60,000 to 100,000 acres of land through easement acquisition and land purchases through federal, state, and private funding sources. The organization will continue making contacts with influential people addressing issues of concern.

GRHA had the opportunity yesterday to present to the St. Peters Mayor and Board of Aldermen about the exciting work happening in the Confluence through our partnership with St. Charles County.

The presentation highlighted GRHA's mission in the Confluence, the future park project, and the importance of protecting this unique landscape for future generations.

We are grateful for the invitation to speak from Mayor Len Pagano and the Board of Aldermen. It was a valuable opportunity to continue building relationships and sharing the vision for what this project can become.

A special thank you to Jim Blair and Chris Hyams for doing an outstanding job presenting and answering questions!

🌿 Throughout American Wetlands Month, we’re highlighting the importance of wetlands and the wildlife that depends on them. From migratory shorebirds to iconic birds of prey, healthy wetlands provide critical habitat for countless species across the Confluence region.

🦅 Species Spotlight: Bald Eagle 🦅

Once endangered in the lower 48 states, Bald Eagles have made an incredible comeback — and healthy wetlands continue to play an important role in their survival.

💧 Why wetlands matter to Bald Eagles:
• Wetlands, rivers, and floodplain habitats provide abundant fish and waterfowl, which are important food sources for eagles.
• Large trees near wetlands and waterways offer ideal nesting and roosting sites with access to food and open water.
• Healthy wetland ecosystems support the biodiversity and habitat conditions bald eagles rely on throughout the year.

The Confluence region is especially important for Bald Eagles during the winter months, when eagles gather near open water along the Mississippi River in search of food.

Protecting wetlands means protecting the habitats that support one of America’s most iconic species.🌿

On May 15th, Great Rivers Habitat Alliance celebrated the life of one of our founding members, Garth Fort, at St. Peter's Episcopal Church.

Garth was a devoted family man, passionate outdoorsman, and a true champion of the Confluence. He loved duck hunting, fishing, and protecting the places and traditions that mean so much to all of us.

Thank you, Garth, for the legacy you helped build and the impact you made on this region we all cherish. Rest easy — we will keep the watch.

Progress is being made in the Confluence, but the fight isn’t over.

After advocacy efforts from organizations like GRHA and community members like you, Ameren has rerouted the majority of proposed transmission lines away from sensitive wetlands in St. Charles County. That’s a win worth acknowledging. But some wetlands remain at risk under the current proposed route, and the decisions being made right now will have lasting consequences for the wildlife and wild places we all care about.

Your voice matters in this process. Here’s how to use it:

Attend an upcoming open house in St. Charles County:

📅 Monday, June 8 | Venue 827, 3448 Harry S Truman Blvd, St. Charles | 11 a.m. - 1 p.m. or 5 - 7 p.m.

📅 Tuesday, June 9 | Knights of Columbus Hall, 1270 Church Road, St. Paul | 11 a.m. - 1 p.m. or 5 - 7 p.m.

Submit a public comment directly to Ameren at [email protected] or through the interactive map at ameren.com/reliability/transmission/eastern-mo-grid.

🌿 Why Wetlands Matter 🌿
It’s American Wetlands Month, and we’re highlighting the incredible value wetlands provide for wildlife, water, and our communities.

Wetlands act like nature’s sponge — absorbing floodwater, filtering pollutants, and helping recharge groundwater supplies. They provide critical habitat for migratory birds, fish, amphibians, pollinators, and countless other species that depend on healthy wetland ecosystems to survive.

Here in the Confluence, wetlands also play an important role in protecting water quality, supporting outdoor recreation, and preserving the natural landscapes that make this region special.

When we protect wetlands, we’re protecting clean water, wildlife habitat, flood resilience, and future generations’ connection to the outdoors.

Tonight is the vote.

We encourage residents and supporters to attend the City Council meeting and urge council members to vote YES on this measure to help protect our community, water resources, and floodplain. We remain opposed to data centers and other large-scale development within the wellhead protection district and/or the 100-year floodplain.

📍 St. Charles City Hall – 4th Floor
📅 Tuesday, May 19
🕖 7:00 PM

Your voice and presence matter.

The 100-year floodplain in the Confluence is not a blank slate for industrial development. It is a living system that supports wildlife, clean water, agriculture, and one of the most important migratory bird corridors on the continent.

The St. Charles City Council will be holding a public meeting on Tuesday, May 5th at 7 PM on the 4th floor of City Hall to consider an ordinance that would affect future development in regards to data centers. This meeting is open for public comment, and your voice matters.

If you care about protecting the Confluence, we encourage you to attend. If you'd like to speak, fill out a speaker card before the meeting begins.

GRHA has submitted a formal letter outlining our concerns about large-scale industrial development within the 100-year floodplain, including risks to groundwater, wetland habitat, flood resilience, and the communities that depend on this landscape.

We will be there. We hope you will be too.

🚨The Confluence needs you, and you are delivering.🚨

When we asked you to speak up, you did. Hundreds submitted comments to Ameren and shared our posts, and it worked. Ameren revised their proposed transmission line routes, reducing the impact to critical wetlands and wildlife habitat at the Mississippi-Missouri Confluence.

But our work is not done.

GRHA met with Ameren this past Friday alongside key stakeholders. We made our position clear: no new routes east of Highway 79. Stick to existing corridors. Protect the Confluence.

A few proposed routes still threaten sensitive wetlands, migratory bird habitat, and local businesses. Ameren wants to hear from ALL stakeholders, and they have confirmed that public comments are making a difference.

Here is how you can help today:

- Visit Ameren's interactive map comment system
- Mark your location of concern
- Note habitat, wildlife, and infrastructure sensitivities
- Submit your comments in your own words (up to 1,000)

Comment here: https://experience.arcgis.com/experience/ebabc211127c4c879ac5e6c2b836ffaa

Urge Ameren to keep all lines to existing routes and eliminate the remaining routes threatening wetlands and the broader Confluence ecosystem.

Your voice is working. Keep the pressure on.

Great Rivers Habitat Alliance is proud to announce a new three-year partnership with Gateway Area Chapter SCI -- a $15,000 commitment to expand hunting access and education right here in our region.

Through this partnership, Gateway Area Chapter SCI will help GRHA fund clinics at the Henges Center designed specifically for veterans, first responders, women, and first-time hunters. This is conservation in action -- connecting more people to the outdoors and to the traditions that sustain it.

We are grateful for SCI's investment in our mission and in the next generation of hunters and conservation advocates.

Stay tuned for clinic announcements coming soon!
