Supplemental groundwater level, spring flow, and streamflow data for the Water Resources Inventory of the Las Cienegas National Conservation Area, Southeastern Arizona

This data release contains hydrologic datasets used in U.S. Geological Survey Scientific-Investigations Report 2023-XXXX that are not available from other sources such as the National Water Information System (NWIS). The hydrologic datasets include groundwater levels, spring and stream discharge measurements, and lengths of perennial streamflow reaches, collected within the Las Cienegas National C

Model Archive for indirect discharge computation for a 300-meter reach of Sand Creek, Wyoming, USA, 2023

This product includes a model archive using the iRIC-SAC Solver for indirect discharge computation of the spring snowmelt peak flow surveyed on May 27, 2023, and estimated to have occurred in early April 2023. The best-fit discharge for this flood is 3,500 ft3/s. Other data include topographic cross-section data, control points, and high-water marks collected by RTK GPS, and selected photographs o

Groundwater-withdrawal and well-construction data in the Upper Colorado River Basin from Arizona, Colorado, New Mexico, Utah, and Wyoming state databases, 1980–2022

The U.S. Geological Survey developed a coupled groundwater and surface-water flow (GSFLOW) model to represent the aquifers of the Colorado Plateau and Upper Colorado River Basin. The study area covers approximately 142,000 square miles and includes parts of Arizona, Colorado, New Mexico, Utah, and Wyoming. To support this modeling effort, groundwater well withdrawal volume data were needed from Ja

Estimated crop irrigation water use withdrawals in Willcox Groundwater Basin, Arizona for 2022

Observations of irrigated agricultural land within the Willcox Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification twice in 2022; crop verification occurred first on May 17th and again on August 26th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizo

Estimated crop irrigation water use withdrawals in San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin, Arizona for 2022

Observations of irrigated agricultural land within the San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin. Digitized field boundaries were used to locate crops for in situ verification twice in 2022; crop verification occurred first on May 18th and again on August 24th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program Co

Estimated crop irrigation water use withdrawals in Hualapai Valley Groundwater Basin, Arizona for 2022

Observations of irrigated agricultural land within the Hualapai Valley Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification once in 2022; crop verification occurred on June 2nd. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizona and supplemented with

Estimated crop irrigation water use withdrawals in Sacramento Valley Groundwater Basin, Arizona for 2022

Observations of irrigated agricultural land within the Sacramento Valley Groundwater Basin in Arizona. Crops were verified in situ once in 2022 on May 31st; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizona and supplemented with Landsat and Sentinel2 imagery collecti

Colorado River at Windy Gap near Granby, CO - 2022/06/13 Water Surface Velocity Map Using Particle Image Velocimetry

The dataset consists of a .csv and shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Windy Gap near Granby, CO, on June 13, 2022. The dataset contains approximately 2 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned

Illinois River at Marseilles, IL - 2022/06/07 Field Measurements of Flow Velocity

Field measurements of flow velocity were acquired from a reach of the Illinois River at Marseilles, IL, on June 7, 2022, to support research on estimating surface flow velocities from remotely sensed data via particle image velocimetry (PIV). The velocity measurements included in this data release were obtained using a TRDI RiverPro acoustic Doppler current profiler (ADCP) deployed from a boat wit

Repeat microgravity data from Santa Cruz River, Tucson, Arizona, 2019-2022

Relative-gravity surveys were carried out using a ZLS Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical gradients

Gravity data along the Little Colorado River near Leupp, Arizona, 2020-2021

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a ZLS Coporation Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations, or between ab

Data from "Gravity surveys for estimating possible width of enhanced porosity zones across structures on the Coconino Plateau, Coconino County, North-Central Arizona."

This dataset includes gravity observations collected on the Coconino Plateau, Arizona, from 2015 to 2019 and reductions that were used to arrive at the gravity residual reported in the associated publication (Wildermuth, XXXX). Relative-gravity surveys were carried out using ZLS Burris relative-gravity meter. Absolute gravity values were taken from the closest NGS stations and relative-gravity dif
