Idaho's Large River Ambient Monitoring Network
From 1989 to 2009, the U.S. Geological Survey, in cooperation with the Idaho Department of Environmental Quality, monitored trends in water quality and biological integrity at more than 50 USGS streamgage stations on rivers throughout Idaho. In 2018, multiple State and Federal partners restarted a portion of the Large River Ambient Monitoring (LRAM) network.
Sediment Transport in the Yankee Fork Salmon River
The Yankee Fork of the Salmon River is one of the larger watersheds in the upper Salmon River subbasin of central Idaho. Mining activities since the late 19th century, specifically placer mining and associated dredging from 1940 to 1953, have left the fluvial system in a highly altered and unnatural state. To improve aquatic and terrestrial habitat in the Yankee Fork, the Bureau of Reclamation...
Monitoring Sediment and Turbidity in Clear Creek
To help protect critical salmonid spawning habitat, we are monitoring streamflow, water temperature, turbidity, and suspended sediment concentrations on Clear Creek upstream of the confluence with the Middle Fork Clearwater River. We are conducting this monitoring in cooperation with the Nez Perce Tribe.
Estimating Seepage Rates of Streams, Ponds, and Lakes at the Camas National Wildlife Refuge
The Camas National Wildlife Refuge provides 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...
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.
Water exchange between...
Evaluation of seepage and discharge uncertainty in the middle Snake River, southwestern Idaho
The U.S. Geological Survey, in cooperation with the State of Idaho, Idaho Power Company, and the Idaho Department of Water Resources, evaluated seasonal seepage gains and losses in selected reaches of the middle Snake River, Idaho, during November 2012 and July 2013, and uncertainty in measured and computed discharge at four Idaho Power Company...

Water resources data, Nevada, water year 2004
Bonner, Laurie J.; Evetts, David M.; Swartwood, James R.; Wilson, Jon W. Ground-water pumpage and artificial recharge estimates for calendar year 2000 and average annual natural recharge and interbasin flow by hydrographic area, Nevada
Nevada's reliance on ground-water resources has increased because of increased development and surface-water resources being fully appropriated. The need to accurately quantify Nevada's water resources and water use is more critical than ever to meet future demands. Estimated ground-water pumpage, artificial and natural recharge, and interbasin...
Lopes, Thomas J.; Evetts, David M. Preliminary hydraulic analysis and implications for restoration of Noyes Slough, Fairbanks, Alaska
The present-day channels of the Chena River and Noyes Slough in downtown Fairbanks, Alaska, were formed as sloughs of the Tanana River, and part of the flow of the Tanana River occupied these waterways. Flow in these channels was reduced after the completion of Moose Creek Dike in 1945, and flow in the Chena River was affected by regulation from...
