Wood River Valley Groundwater-Flow Model

Rapid population growth in the Wood River Valley since the 1970s has caused concern about the long-term sustainability of the groundwater resource. Water-resource planners and managers, as well as other decision makers, need a tool for water rights administration and water-resource management and planning.

Groundwater-Flow Model for the Treasure Valley and Surrounding Area

in partnership with the Idaho Department of Water Resources (IDWR) and Idaho Water Resource Board (IWRB), we will construct a numerical groundwater-flow model of the Treasure Valley and surrounding area. Resource managers will use the model to simulate potential anthropogenic and climatic effects on groundwater for water-supply planning and management. As part of model construction, the...

Streamflow Evaluation for Water Right Claims for Wild and Scenic Rivers, Owyhee Canyonlands Wilderness

Several river segments in the Owyhee Canyonlands Wilderness have been designated as “Wild and Scenic” under the Omnibus Public Lands Management Act of 2009. This designation is intended to protect the “outstanding remarkable values” (ORVs) in this area—specifically fish and wildlife habitat, scenic and geological features, and recreational opportunities.

The Bureau of Land Management (...

Estimating Seepage Rates of Streams, Ponds, and Lakes at the Camas National Wildlife Refuge

The Camas National Wildlife Refugeprovides essential resting, feeding, and nesting habitat for waterfowl including migratory birds. A variety of other animals, large and small, are found there, too. Since the refuge was established in 1937, the U.S. Fish and Wildlife Service (USFWS) has been responsible for managing this vital resource.

Traditionally, Camas Creek and groundwater inflow...

Wood River Valley Hydrologic Trends and Comparisons

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.

Lower Granite Reservoir Bathymetric and Underwater Video Surveys

Sedimentation of Lower Granite Reservoir, operated by the U.S. Army Corps of Engineers, affects commercial navigation and reservoir storage capacity. Some groups are concerned that dredging the reservoir to remove excess sediment may negatively affect endangered species such as steelhead and salmon.

Lower Granite Reservoir Bed Sediment Coring and Analysis

Some groups are concerned that dredging the reservoir and the confluence of the Snake and Clearwater Rivers to remove excess sediment may mobilize contaminants in sediment that could negatively affect endangered species such as steelhead and salmon.

Wood River Valley Hydrogeologic Framework

To make scientifically based water-resource decisions, elected officials, water managers, and the general public need additional information about the Wood River Valley aquifer system. A crucial part of this information is an improved understanding of the extent, thickness, and hydraulic properties of the aquifer—a hydrogeologic framework.

Wood River Valley Aquifer System - Water-Quality Assessment

A component of groundwater availability is whether the water quality is suitable for a particular use. Elected officials, water managers, and the general public have raised concerns about whether water quality has been affected in developed and agricultural areas by wastewater disposal, fertilizer application, and animal waste.

Geochemical Analysis of Groundwater in Eastern Ada County

Groundwater is the primary source of water supply to Ada County’s growing population. Because of a proposed development near Mayfield, the Idaho Department of Water Resources (IDWR) initiated the East Ada County Hydrologic Project to improve the scientific understanding of the groundwater resources in the area.

Assessing Groundwater/Surface Water Interaction and Stream Discharge Uncertainty in the Snake River

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.
