Sediment accumulation rates and volume in Pahranagat Wash above Arrow Canyon Dam in northern Moapa Valley, Nevada Sediment accumulation rates and volume in Pahranagat Wash above Arrow Canyon Dam in northern Moapa Valley, Nevada
An evaluation of sediment deposition rates and volume of impounded sediments in Pahranagat Wash behind Arrow Canyon dam in southeastern Nevada was done between 2016 and 2022. Data were collected and interpreted to address concerns by the Moapa Band of Paiutes and local historical preservation groups regarding the burial of culturally important sites by the impounded sediment deposited...
Conceptual and numerical groundwater flow model of the Iowa River alluvial aquifer near Tama County, Iowa, 1980 through 2022 Conceptual and numerical groundwater flow model of the Iowa River alluvial aquifer near Tama County, Iowa, 1980 through 2022
The Iowa River alluvial aquifer is an important source of water on the Meskwaki Settlement in Tama County, Iowa, which is land owned by the Sac & Fox Tribe of the Mississippi in Iowa (commonly known as the Meskwaki Nation). The U.S. Geological Survey constructed a groundwater flow model, including a conceptual and numerical model, of the Iowa River alluvial aquifer and underlying...
Geochemistry and Soils of the Big Smoky Valley Fens, Nevada Geochemistry and Soils of the Big Smoky Valley Fens, Nevada
Fens are groundwater-fed wetlands that can provide habitat for plants and animals. Due to anthropogenic activities and climate change, many fens around the world are at risk. This paper presents the results of a study of the hydrology and geochemistry of fens in Big Smoky Valley, central Nevada to support the Bureau of Land Management’s activities in the area. A water sample from the...

Evaluation of Streamflow Depletion Related to Groundwater Withdrawal, Humboldt River Basin
This project evaluates how groundwater withdrawals affect streamflow in the Humboldt River Basin. It focuses on understanding the timing, magnitude, and causes of streamflow depletion, including agricultural pumping and mine dewatering, to support sustainable water management in Nevada.
Science in the Humboldt River Basin
The Humboldt River flows east to west through north-central Nevada and is about 330 miles long. It is an important water source for residents and agriculture, and it also supports one of Nevada’s largest industries—gold mining. Most of the state’s mines are in the Humboldt River Basin along the Carlin Trend. Nevada produces about 72 percent of all U.S. gold, making it the fifth largest producer in...
Evaporation from Lake Mead and Lake Mohave, Lower Colorado River Basin, Nevada and Arizona
Since 2010, the U.S. Geological Survey (USGS) Nevada Water Science Center (NVWSC) has worked with with the Bureau of Reclamation to update evaporation estimates for Lake Mead.
