Streambank
erosion can contribute substantial sediment and phosphorus loasds
to rivers. This site along the Kalamazoo River in Ross Township
was restored with log tie-backs, rock rip-rap and native plantings.
The "before and after" photos illustrate the dramatic
improvement in the site. It was estimated that the restoration stopped
71 pounds of phosphorus from entering the river annually. Additional
"after" photos are shown below.
A streambank
erosion survey was conducted on the main stem of the Kalamazoo
River in 2003. Sediment and phosphorus loading was estimated from
each site of erosion. It was estimated that the sites surveyed contribute
over 650 pounds of phosphorus to the Kalamazoo River annually.
