The Iowa Department of Natural Resources says projects to stabilize the Lake Delhi dam and the former lake bed are nearly complete. When the dam was breached last July draining the lake, silt that had built up was gradually released downstream.
Officials with the DNR says one project is designed to stem erosion by removing much of the accumulated silt and adding rock riffles to the lake bed. Officials say the second project shored up the remaining portion of the dam with loose rock and creating a stilling pond upstream of the area where the dam was breached.
Officials say the projects should reduce the amount of silt being washed downstream.
