Bank Stabilization Using Bankform Roughness--Johns Demonstration Project, Barry Duff

Clark Fork Symposium Archives

A meander bend in the Upper Clark Fork River, just upstream of the confluence with Dempsey Creek, actively eroded in recent years. The outer bank had no deep-rooted vegetation. Bank soils consist of an upper cohesive layer of silts and clays and a lower cohesionless layer of sand and gravel. The bank was undermined as the cohesionless layer was eroded, and the overlying cohesive layer would eventually collapse into the river.

The purpose of the demonstration project was to stabilize the streambank by increasing bankform roughness using natural materials (large willows, small shrubs, and willow cuttings). The bankform was intermittently …

Upper Clark Fork River Demonstration Projects, Montana, Barry Duff

Clark Fork Symposium Archives

Since 1990, a number of demonstration projects have been completed in the Upper Clark Fork River Basin. Projects have addressed the riparian zone, the floodplain, and upland areas. The projects include the , the RIT Project, the Governor’s Demonstration Project , the University of Montana Riparian and Wetland Research Program (RWRP) Streambank Stabilization Pilot Study, the South Deer Lodge Entryway Improvement Project, the Upland Till Demonstration Project, and, most recently, the Allan Johns Bank Stabilization Demonstration Project. ARCO has been the source of funding for most of these projects. Since the original construction, these demonstration projects have been monitored to …

Time Critical Removal Action In Response To Contaminated Soils Along The Eastside Ditch Near Deer Lodge, Montana, G. S. Vandeberg, D. J. Dollhopf, Dennis Neuman, P. D. Smith, W. Bluck, S. Brown

Clark Fork Symposium Archives

Some irrigated lands along the Clark Fork River, near Deer Lodge, Montana contain elevated levels of arsenic, cadmium, copper, lead and zinc, and low soil pH. This contamination originated from river-transported mine wastes associated with metal mining, milling and smelting operations in the Butte and Anaconda, Montana areas. In May 1999, the U.S. Environmental Protection Agency ordered the responsible party (ARCO) to reduce contamination on historically irrigated lands along the Eastside Ditch near Deer Lodge, Montana. These lands consist of residential properties and adjacent pastures. The preferred action for the residential yards is excavation and replacement of soils (up to …
