Real-time Monitoring

Mining of stibnite (antimony sulfide), tungsten, gold, silver, and mercury near the town of Stibnite in central Idaho has left a legacy of trace element contamination in the East Fork of the South Fork of the Salmon River (EFSFSR) and its tributaries. Concentrations of arsenic, antimony, and mercury frequently exceed human health criteria and may impact threatened or endangered salmonid species...

We partner with the EPA to conduct long-term water-quality and streamflow monitoring in the Coeur d’Alene River Basin, which has been widely impacted by historic mining activities.

Wood River Valley residents rely on groundwater for domestic supply, either from domestic or municipal-supply wells. The rapid population growth since the 1970s has caused concern about the long-term sustainability of the groundwater resource.

Because fluvial sediment poses both economic and ecological problems, resource managers need a safe, cost-effective way to measure sediment in streams, particularly in remote areas.

Are there ways to manage sediment before it accumulates in Lower Granite Reservoir? If so, resource managers must know exactly how much sediment is being transported in the lower Snake and Clearwater River basins, the grain-size distribution of the sediment that is being transported, which subbasins are contributing the most sediment, and how the sediment is being deposited once it is delivered to...

The State of Idaho needs to determine stream discharge, adjusted to remove fluctuations resulting from the operation of hydropower facilities, in the Snake River below Swan Falls Dam near Murphy, Idaho. The State will use this information to distribute water to owners of water rights in the middle Snake River, particularly at thresholds of 3,900 and 5,600 ft3/s. Water exchange between surface...
