Salinity

Approximately 6.4 million tons of dissolved solids are discharged from the Upper Colorado River Basin (UCRB) to the Lower Colorado River Basin each year. This results in substantial economic damages, and tens of millions of dollars are spent annually on salinity control projects designed to reduce salinity loads in surface waters of the UCRB. Dissolved solids in surface water and groundwater...

Ground-water Budgets

Ground-water budgets are commonly used in water-resource studies to gain a better understanding of the groundwater-flow system. The hydrologic cycle in the basin can be represented by a long-term water budget in which inflows are balances by outflows and, thus, no long-term change in storage occurs. The water budget can be evaluated through use of two internal budgets and their corresponding...

Baseflow

The Colorado River has been identified as the most overallocated river in the world. Considering predicted future imbalances between water supply and demand and the growing recognition that base flow (a proxy for groundwater discharge to streams) is critical for sustaining flow in streams and rivers, there is a need to develop methods to better quantify present-day base flow across large...

Transboundary Aquifer Assessment Program (TAAP)

Transboundary aquifers are an essential source of water for United States – Mexico border communities. Declining water levels, deteriorating water quality, and increasing use of groundwater resources on both sides of the border raise concerns about the long-term availability of this supply.

The U.S. – Mexico Transboundary Aquifer Assessment Act (Public Law 109-448) of 2006 was enacted...

Development of landscape variables to inform models of meadow vulnerabilities and adaptation under changing climate

The USGS Nevada Water Science Center is providing technical assistance for the collection of landscape variables hypothesized to influence meadow responses to climate and restoration activities. These data will be used in a decision support framework developed by the U.S. Forest Service (USFS) and Desert Research Institute (DRI).

Assessment of Springsnail Abundance at Ash Meadows National Wildlife Refuge

USGS Nevada Water Science Center (NVWSC), in cooperation with the U.S. Fish and Wildlife Service (FWS), is performing a systematic field investigation designed to survey the status of springsnails and the condition of the springs in which they occur at Ash Meadows National Wildlife Refuge (AMNWR).

Rio Grande Transboundary Integrated Hydrologic Model: Modeling Conjunctive Use to Support Resource Management

The Palomas, Mesilla, and Conejos-Médanos Basins in New Mexico, Texas, and northern Mexico compose a geologically and hydrologically complex region. The conjunctive use of surface water and groundwater takes place under a myriad of legal and operational constraints, including the Rio Grande Compact, an international treaty, and the U.S. Bureau of Reclamation’s Rio Grande Project. New demands...

Geochemical Evidence of Groundwater Flow Paths and the Fate and Transport of Constituents of Concern in the Alluvial Aquifer at Fort Wingate Depot Activity, New Mexico

As part of an environmental investigation at Fort Wingate Depot Activity, New Mexico, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, interpreted aqueous geochemical concentrations to better understand the groundwater flow paths and the fate and transport of constituents of concern in the alluvial aquifer underlying the study area. The fine-grained nature of...

Hydrogeologic and geochemical characterization and evaluation of two arroyos for managed aquifer recharge by surface infiltration in the Pojoaque River Basin

In order to provide long-term storage of diverted surface water from the Rio Grande as part of the Aamodt water rights settlement, managed aquifer recharge by surface infiltration in Pojoaque River Basin arroyos was proposed as an option. The initial hydrogeologic and geochemical characterization of two arroyos located within the Pojoaque River Basin was performed in 2014 and 2015 in...

The Source of Groundwater and Solutes to Many Devils Wash at a Former Uranium Mill Site in Shiprock, New Mexico

The Shiprock Disposal Site is the location of the former Navajo Mill, a uranium ore-processing facility, located on a terrace overlooking the San Juan River in the town of Shiprock, New Mexico.The milling operations, conducted at the site from 1954 to 1968, created radioactive tailings and constituents of concern that are now found in the groundwater beneath the Mill. Elevated concentrations...

Water Resource Assessment of the Rio San Jose Basin, West-Central New Mexico

Water resources in the Rio San Jose Basin are limited, and development for public supply, mining, agriculture, and commercial activities have the potential to affect the water availability and quality at a basin-wide scale. This study is designed to provide water-resource managers with better information to plan for potential effects of increased or shifting demands and changes of climatic...
