Rice Creek Meander Restoration
Meanders on Rice Creek
The project will improve fish and invertebrate habitat by restoring pools and riffles, thereby increasing and diversifying habitat for aquatic life. Each riffle would be built so it is in the backwater of the next riffle. This would work in harmony with natural sedimentation and erosion by the river, minimizing erosion of the riffle and relying on nature's tendency to build up the creek bed at certain points.
By restoring the wetland hydrology, water quality will be improved. Wetlands act as natural filters and natural sponges that absorb excess water and release it slowly, thereby reducing flooding. Adding meanders will also improve water quality by slowing the water down, which will reduce erosion and the sediment load in the water.
There is a good chance that when the project is complete, park users might not realize that there ever was a project there. Bird-watchers might not be aware that the vegetation was replanted. Canoe enthusiasts might not know that the depths and widths determining the creek’s velocity and sinuosity were carefully calculated and that the rocks were strategically placed. If that happens, the project will be a tremendous success.
