Surface Water Data

Per- and polyfluoroalkyl substances (PFAS) are widespread anthropogenic chemicals that have been in use for the past 70 years. This class of compounds comprises thousands of chemicals including perfluorosulfonates (PFSAs) such as perfluorooctane sulfonate (PFOS), perfluorocarboxylic acids (PFCAs), and perfluorooctanoic acid (PFOA). As the use of these chemicals has grown so has their ubiquity in...

The Rio Grande is a vital water source for Colorado, New Mexico, Texas and northern Mexico. A model was developed to determine how Rio Grande streamflow could change in the future. Both streamflow timing and volume displayed substantial potential changes. However, streamflow timing was most affected, and runoff could arrive a month earlier than the historic average if temperatures continue to warm...

Metals attached to suspended sediments or dissolved in river water pose a potential health risk to communities that depend on that water for agricultural and domestic uses. Exceedances of Navajo Nation surface water quality standards for metals (especially lead and arsenic) indicate that communities on the Navajo Nation along the San Juan River are exposed to this potential risk. Sources for these...

The United States Geological Survey (USGS) New Mexico Water Science Center (NM WSC), in cooperation with the U.S. Fish and Wildlife Service (USFWS), U.S. Environmental Protection Agency (USEPA), U.S. Army Corps of Engineers (USACE), U.S. Bureau of Reclamation (Reclamation), Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA), and Bernalillo County (BERNCO), will measure and analyze...

Webcams have been installed at five real-time stream-gaging sites. The webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river environments during storms.

The Tri-County Resource Management Plan/Environmental Impact Statement (RMP/EIS) “decision area” (the public lands and resources that are managed by the Bureau of Land Management in Sierra, Doña Ana, and Otero Counties) is a large (4,375 square miles) and varied landscape. The decision area contains both connected and closed surface-water and groundwater basins, some of which cross state and...

As part of the surface-water drainage system of the Albuquerque metropolitan area, numerous ephemeral channels collect and transport surface water through the urban area and, eventually, into the Rio Grande.

The Las Conchas fire started on June 26, 2011, near the small community of Las Conchas in the Jemez Mountains of north-central New Mexico. When the fire was contained on August 3, 2011, it had burned 156,593 acres of mixed conifer, pinyon/juniper, and ponderosa forest. At the time, it was the largest wildfire in New Mexico history. Peak burn severity was extreme; over 60,000 acres of the total...

Estimates of streamflow are needed for a wide variety of applications, including water-resources planning and management, flood-plain mapping, and instream flow determinations. Surface water is the primary source of water for irrigators along major stream corridors in New Mexico and is increasingly being utilized by large municipalities. While streamflow statistics for gaged sites are readily...

The New Mexico Water Science Center (NMWSC) has historically conducted NAWQA data collection of groundwater and surface water-data within the former Rio Grande Valley (RIOG) study unit, which covers about 45,700 square miles in Colorado, New Mexico, and Texas.

On August 5, 2015, about three million gallons of water and sediment were released from the Gold King Mine near Silverton, Colorado, into Cement Creek, a tributary of the Animas River. The New Mexico Environment Department, among other State, Tribal, and local entities in CO, NM, and UT, is concerned that metals associated with the water and sediment released from the Gold King Mine could have...

Streamflow data are needed at many sites on a daily basis for forecasting flow extremes, making water-management decisions, assessing current water availability, managing water quality, and meeting legal requirements. These activities require streamflow information at a given location for a specified time. These needs generally are best satisfied by operating a station to produce a continuous...
