COMPLETED: Using thermal imagery to assess wolf hairloss from sarcoptic mange

Researchers at NOROCK and their partners used thermal cameras at the Grizzly and Wolf Discovery Center in Montana to assess the amount of heat lost under a range of environmental conditions with and without hair. These methods help scientists better understand how mange operates in wild wolves throughout the Greater...

Cascades Volcano Observatory (CVO)

The CVO staff conduct research on many aspects of active volcanism, respond to dangerous volcanic activity in many parts of the world, and maintain a close watch over volcanoes in Washington, Oregon and Idaho. The USGS established CVO in Vancouver, Washington, after the May 18, 1980, eruption of Mount St. Helens.

Panther Creek: Evaluating Recovery of a Mining-Damaged Stream Ecosystem

Historically, Idaho has been home to many productive underground and open-pit mining operations. These activities have also produced water quality problems in some areas. One such example is the Blackbird Mine in central Idaho. Following mining operations from the 1940s through the 1960s, Panther Creek and its tributaries were severely damaged by runoff from the Blackbird Mine. Water-quality...

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.

Evaluating Geothermal Groundwater Levels to Support Bruneau Hot Springsnail Recovery

The endangered Bruneau hot springsnail (Pyrgulopsis bruneauensis) exists only in a geographically limited habitat of thermal springs and seeps in southwestern Idaho. As a part of its 2002 recovery plan for the springsnail, the U.S. Fish and Wildlife Service (USFWS) targeted conservation efforts to increase groundwater levels in the Bruneau area to protect the geothermal spring discharges...

Recharge and frozen ground in the PNW

The Issue: Seasonally frozen ground occurs over approximately one-third of the contiguous United States, and the extent and duration of frozen ground have been decreasing as a result of global warming. In semi-arid regions such as the Columbia Plateau and Snake River Plain in the Pacific Northwest, nearly all natural recharge occurs between October and March when intermittent...

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.

Coeur d'Alene Lake Water Budget

Development around Coeur d'Alene Lake has accelerated over the past 25 years. Commercial and residential development adjacent to the lake plus demands for irrigation, recreation, and hydropower raise concerns about the potential for declining lake levels.

A comprehensive lake water budget helps resource managers determine the possible effects of growth on lake levels.

Coeur d'Alene Lake Water Quality

The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been discharged directly to or washed into...

Phosphorus SPARROW Model for the Yakima River

The Issue - During the 2004-07 irrigation season, nutrient concentrations in the lower Yakima River were high enough at certain times and locations to support the abundant growth of periphytic algae and macrophytes which resulted in large daily fluctuations in dissolved oxygen concentrations and pH levels that exceeded the Washington State water-quality standards for these...

A USGS grizzly bear researcher snapped this picture of a mother grizzly bear and her cub in Yellowstone National Park. Recent research shows that fffspring of grizzly bear mothers with a history of human-bear conflicts are more likely to be involved in human-bear conflicts than offspring of mothers without a history of human-bear conflicts.

Lightning Creek at Clark Fork, Idaho: December 9, 2015

On December 9, 2015, heavy rain and resulting snowmelt swelled many Pacific Northwest rivers to flood stage. One of these streams was Lightning Creek at Clark Fork, Idaho. In a 24-hour period, Lightning Creek rose from about 200 cubic feet per second (cfs) to more than 10,000 cfs as recorded at USGS strreamgage 12392155.

During August 2013, the Beaver Creek wildfire burned more than 114,000 acres in south-central Idaho. Shortly after the fire was contained, heavy rainfall triggered numerous debris flows, including this one in Badger Gulch.

Groundwater pumping, which has been increasing since the 1940s, now accounts for about one third of the estimated annual flow from the aquifers of the eastern Great Basin. In parts of this region, groundwater pumping exceeds the rate of natural discharge, leading to land subsidence and declines in water levels and spring flow.
