Opinion: Protecting the Confluence
floodplain demands permanent action

‘It is a warning bell’

It is a warning bell — and one that must be answered with permanent
protections and expanded safeguards for the entire 100-year floodplain.

Great Rivers Habitat Alliance

Our Goals

Founded in 2000 to directly combat the commercial development
of the 100-year Confluence floodplain through policy, protection,
conservation, public awareness and education.

Great Rivers Habitat Alliance

Our Mission

Protecting the 100-year Confluence floodplain for the benefit of wildlife,
historic waterfowling, agriculture, clean water and people.

Great Rivers Habitat Alliance

Our Programs

Great Rivers Habitat Alliance implements a number of initiatives
dedicated to preserving the natural resources of the floodplain.
We strive to educate the public on the importance of limiting
Big River flood plain development.
