Hell Roaring Creek - stream restoration

IMA designed, permitted, and constructed a stream restoration project on the uppermost tributary of the Missouri River. The project combined traditional restoration techniques with low-tech, process-based methods to restore natural stream function. Beaver Dam Analogs (BDAs) and Post-Assisted Log Structures (PALS) were used to enhance floodplain connectivity, reactivate side channels, and broaden riparian habitat.

Bank erosion was addressed with several different techniques

Bank erosion pre-project implementation

Area of bank erosion restored with grading, small woody debris, and native plants

Beaver dam analogs installed on a secondary channel to increase floodplain connectivity and riparian vegetation
