The East Gallatin River has a long history of impacts from agriculture and urban development. With rapid conversion of land use from agriculture to small tracts and subdivisions, more people are building homes along streams without being aware of the natural tendency of rivers to migrate. Thus, more and more applications for bank stabilization permits are being submitted, generally involving riprap, especially in high water years. Riprap is generally oversized and excessive in streams the size of the East Gallatin River. GWC and project partners, Trout Unlimited and Fish, Wildlife and Parks, hoped that this project would help to demonstrate effectiveness of different techniques at halting bank erosion.
The project included construction of bank stabilization measures using native bioengineering and large woody debris techniques where possible and riprap repair in one discreet locations to ensure stability. Benefits of the project include reduction in fine sediment loading, added woody debris habitat, and added riparian vegetation. This project was a partnership between Trout Unlimited, Montana Fish, Wildlife and Parks, GWC and the private landowner. Funding was provided in part by the Montana Watershed Coordination Council’s Watershed Fund.
