Data

The U.S. Geological Survey (USGS), in cooperation with the New Mexico Department of Transportation, estimated the magnitude and frequency of floods corresponding to the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs; otherwise known as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods, respectively) for 346 selected streamgages in New...

Aerial imagery was collected with an uncrewed aerial system (UAS) and ground control points were used to construct a digital elevation model (DEM) and orthomosaic image using Structure-from-motion (SfM) photogrammetry for the Zuni Salt Lake in west-central New Mexico. The DEM and bathymetry survey points were combined to estimate lake water volume as a function of lake stage in the U.S...

Streamflow in a river can be used to calculate loads of constituents of concern in rivers but obtaining streamflow data using traditional streamgaging techniques in ephemeral channels can be cost prohibitive. Because of the remote location and infrequent flow occurrences, collecting paired stage-streamflow measurements for sufficient flow events during a 2-year study to develop a rating...

This data release presents data and calculations for morphometric parameters, median and maximum unfiltered concentrations used in statistical analyses, and stream lengths through geologic units that contain elevated concentrations of constituents of concern used for the publication, "Morphometric and geologic characterization with statistical correlations for 33 tributary drainage...

This data release includes snow depth and snow water equivalent (SWE) for the water year 2025 during ten separate field campaigns that took place between late December and late May. The field area is comprised of 703 surveyed points in, on the perimeter of, and surrounding six flat field (‘no_slope’) forest openings, four northern hillslope aspect (‘north_slope’) forest openings and four...

The purpose of this data release is to provide water quality data that were collected during a raft sampling campaign near USGS streamgage 372728107475701 (Animas River at Bakers Bridge north of Durango, CO) to USGS streamgage 09364500 (Animas River at Farmington, NM) between the dates 06/06/2022 and 06/10/2022. Chemical and physical parameters were collected at 1-minute intervals with...

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2019 to 2023 in Rio Rancho and Bernalillo County, New Mexico. Relative surveys were conducted using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were conducted using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid...

A dye trace experiment was conducted between March 2023 and September 2024 to understand the connection between treated wastewater effluent discharged to Bright Angel Wash and 13 springs and associated watersheds from Hermit Creek to Pipe Creek along the South Rim of Grand Canyon, Arizona. This data release includes information on the location of the sites (GCSR_Site_Information), time...

These data include snow depth and snow water equivalent (SWE) for a field campaign on April 9, 2024. The field area is comprised of 311 surveyed points in, on the perimeter of, and surrounding six forest openings next to Coal Creek off Coal Bank Pass in the San Juan Mountains in southwestern Colorado, USA. These measurements were taken to look at the relationship between snow...

Situated in a remote corner of northwestern New Mexico, Chaco Culture National Historical Park (CCNHP) was once the center of a sophisticated social, political and architectural civilization with a 50,000-square mile sphere of influence. The park protects the greatest concentration of Chacoan historical sites in the American Southwest and is arguably the most significant prehistoric site...

Sediment traps were deployed in thirty-three ephemeral and perennial tributaries to the San Juan River during 2021 and 2022. This dataset includes the chemical concentrations of the sediment samples collected in sediment traps during storm events. These traps collected sediment during storm events that typically occur as monsoonal convective storms from June to September. Because of the...

The San Juan River is a major water source for communities in the Four Corners region of the United States (parts of Colorado, Arizona, New Mexico, Utah) and is a vital source of water for the Navajo Nation. The Navajo Nation Environmental Protection Agency (NNEPA) periodically samples surface water on the Navajo Nation and has found that some elements exceed NNEPA surface water...
