silver bow creek/butte area

BUTTE TO MILLTOWN RESERVIOR

The boundary of the Silver Bow Creek/Butte Area site begins above Butte, near the Continental Divide, and extends westward along Silver Bow Creek to and including the Warm Springs Ponds (a treatment area). The site covers about 26 miles of stream and streamside habitat. Silver Bow Creek was used as a conduit for mining, smelting, industrial and municipal wastes for more than a hundred years. Vast mine tailings deposits are found along the creek. These deposits contain elevated levels of metals and have been dispersed over the entire flood plain. The site also includes the cities of Butte and Walkerville, as well as the Berkeley Pit and the interconnected mine workings. The Silver Bow Creek/Butte Area site is one of four contamination areas, jointly known as the Clark Fork Basin Sites. Others are Milltown Reservoir Sediments, Anaconda Company Smelter, and Montana Pole & Treating Plant. All are on EPA's National Priorities List.
