Abstract

The urban portion of the Kettle Creek Watershed is experiencing severe bank and bed erosion due to unchecked stormwater runoff and a steep stream slope. The Kettle Creek Urban Watershed Improvement Project will reduce sediment input to the stream by stabilizing the steam bed with rock-riffle stream stabilization structures and stream bank improvements at select locations. Other components of the watershed are being addressed for excess sediment loads including the agricultural portion by constructing sediment detention basins, and the urban stormwater component by separating the existing combined sanitary and stormwater systems. The urban stream erosion factor represents the weak link in the current watershed impairment. The benefits of the all the watershed improvements components will be realized by all the residents of Kettle Creek Watershed as well as the citizens of Ottumwa.
