Activities in 'Montana'

Diel Metal Cycling
description: Recent work has found that dissolved concentrations of some metals fluctuate significantly on a daily cycle in neutral to alkaline streams, and that this phenomenon occurs consistently across the northern Rocky Mountains. The causes, extent, and implications of these diel cycles are being investigated

New World Mining District
description: Metal loadings from mining and non-mining related sources were quantified using tracer-injection and synoptic-sampling techniques in Fisher Creek (1997), Daisy Creek (1999), and Miller Creek (2000) in the New World mining district near Cooke City, MT.

Tenmile Creek
description: Metal loadings from inactive mines were quantified in 1998 using tracer-injection and synoptic-sampling techniques along a 10-mile reach of upper Tenmile Creek near Helena.

Clark Fork River
description: Evaluation of effects of mine wastes on aquatic resources.

Clark Fork River
description: Tailings from the Butte-Anaconda mining and smelting district deposited in the Clark Fork River are under long-term monitoring. Geomorphology, water, bed sediment, and benthic invertebrates along a 200-km reach of the Clark Fork are being investigated to assess potential flood-plain remediation.
