Sawmill Creek Stream Bank Erosion
CX(s) Applied: B1.3
Date: 06/06/2014
Location(s): Illinois
Offices(s): Argonne Site Office
Recent beaver activity created a dam in Sawmill Creek, detaining water in the waterway. This waterway is considers Waters of the State. Storm events in the late winter and early spring, have generated high water levels in the creek. Water going over the beaver dam has eroded part of the south creek embankment near Building 125. The resultant erosion caused a large tree to slide into the creek, exacerbating the erosion and has created a safety hazard for area users. Over time it could impact Laboratory operations in the area including the potential damage to Building 125. The beavers have been removed from the area by the USDA.
