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 of 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.

323 signatures and counting. 177 to go!

The Mississippi–Missouri Confluence Conservation Coalition is working toward 500 signatures on the Declaration for Responsible Routing and Stewardship of the Mississippi–Missouri Confluence.

The Coalition is asking that new transmission lines use existing corridors rather than creating new corridors through the Confluence and the conservation work generations have invested in protecting.

Every signature goes directly to Ameren’s project team and is logged in the official project record.

Help us get to 500:
