URGWOM: Upper Rio Grande Water Operations Model
The Upper Rio Grande (URG) River Basin extends from the headwaters in Colorado to the USGS streamflow gage Rio Grande near Fort Quitman, Texas, and includes both native water and transmountain water from the Colorado River Basin. Because of surface-water allotment issues, input from various sources of water (native and transmountain), numerous reservoirs, and complex stream-aquifer relations...
Discrete Water Quality Sampling in New Mexico
The New Mexico Department of Agriculture (NMDA) is responsible for managing pesticide usage in New Mexico. The NMED contracted with the New Mexico USGS to assist in setting up a sampling plan to monitor pesticides in selected surface water sites throughout the state. The Canadian River Municipal Water Authority (CRMWA) wishes to manage the salinity levels on the Canadian River as it flows into...
Monitoring Network of the Groundwater Flow System and Stream-Aquifer Relations in the Mesilla Basin, Doña Ana County, New Mexico and El Paso County, Texas
The Mesilla Basin monitoring program was established in 1987 to document the hydrologic conditions of New Mexico’s southern-most, Rio Grande rift basin. The program’s data collection and reporting is conducted by the U.S. Geological Survey in cooperation with local, state, and federal agencies. Hydrologic data collected as part of the monitoring program provide valuable information to better...
Prewildfire Assessments of Postwildfire Debris-Flow Hazards
Debris flows are high-density slurries of water, rock fragments, soil, and mud that can have enormous destructive power. Wildfire can drastically increase the probability of debris flows in landscapes that have otherwise been stable. In 2010, the USGS developed the Cannon model to estimate postwildfire debris-flow probabilities and volumes in burned areas. In 2013, with the help of U.S. Forest...
Hydrologic Studies in the East Mountain Area of Bernalillo County, NM
Recent expansion of suburban development and population growth in the Sandia Mountains of eastern Bernalillo County, NM (East Mountain Area, EMA), has led to increased residential and commercial construction and increased demands on available water resources. Information about the spatial and temporal variability of water resources is needed for continued population and economic growth. USGS...
Changes in Groundwater Levels in the Albuquerque Metropolitan Area
The U.S. Geological Survey, in cooperation with the Albuquerque Bernalillo County Water Utility Authority (ABCWUA) has been investigating the effects of groundwater withdrawal on groundwater levels throughout the Albuquerque metropolitan area in the Middle Rio Grande Valley of central New Mexico (fig. 1). Historically, the water supply requirements of the Albuquerque metropolitan area were met...
Aquifer Compaction, Recovery, and Land-surface Elevation Change in the Albuquerque Basin
In many groundwater basins in the arid to semiarid western United States, permanent regional-scale land-surface elevation change has resulted from substantial drawdown of groundwater levels. By the end of 2008, groundwater drawdown from municipal pumping in the Albuquerque area had reached as much as 120 feet below predevelopment (~1950s) water levels. In 2014 the USGS, in cooperation with the...
Bandelier National Monument Postwildfire Flood Support
In the summer of 2011, the Las Conchas Fire burned 156,593 acres in the Jemez Mountains in northern NM including the upper watersheds of Frijoles and Capulin Canyons in Bandelier National Monument. The drastic removal of vegetation in the upper watersheds of these popular tourist destinations left them susceptible to dangerous and record breaking floods. As long as the threat of large post...
USGS Post-Wildfire Hydrologic Monitoring in New Mexico
USGS Gages in New Mexico Wildfire Areas
Floods Analysis
Accurate estimations of flood discharges at bridge or culvert sites is required to provide cost-effective design of that structure. Streamflow-gaging stations, for which flood data are available, are usually located in major perennial drainage basins that are not representative of sites where common bridge and culvert designs are needed. In 1942, the USGS, in cooperation with the New Mexico...
Rio Grande Travel Times
The City of Albuquerque will begin accepting delivery of imported San Juan-Chama water to supplement present municipal water supplies as part of the City's Drinking Water Project (DWP). The City's San Juan-Chama water will be diverted from the Rio Grande near Alameda Bridge in Albuquerque, transported to a treatment facility, and eventually distributed to customers. Water in the Rio Grande is...
Analysis of the Magnitude and Frequency of Peak Discharge in the Navajo Nation and Surrounding Region, Arizona, Utah, Colorado, and New Mexico
Estimates of the magnitude and frequency of peak discharges on unregulated streams at gaging stations or ungaged stream sites in the Navajo Nation in Arizona, Utah, Colorado, and New Mexico are necessary for flood hazard mapping.
