The USGS Wyoming-Montana Water Science Center (WY–MT WSC) recently completed a report documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages operated by the WY–MT WSC. In association with the report, this data release presents peak-flow frequency analyses for 99 selected streamgages that serve as examples showing various aspects of the WY-MT WSC frequency-analysis methods. The results are presented in three child items: a child item containing the results excel spreadsheet,...

The development and the generation of the datasets that are published through this data release, were based on the results and findings of this report: Kohn, M.S. and Patton, T.T., 2018, Flood-Inundation Maps for the South Platte River at Fort Morgan, Colorado, 2018: U.S. Geological Survey Scientific Investigations Report 2018-5114, 14 p., https://doi.org/10.3133/sir20185114. The geospatial dataset contain final versions of the raster and vector geospatial data and its related metadata, and the model archive dataset contains all relevant files to document and re-run the surface-water hydraulic model that are discussed in the report. Digital flood-inundation maps for a 4.5-mile reach of the South Platte River at...
Groundwater is an often overlooked freshwater resource compared to surface water, but groundwater is used widely across the United States, especially during periods of drought. If groundwater models can successfully simulate past conditions, they may be used to evaluate potential future pumping scenarios or climate conditions, thus providing a valuable planning tool for water-resource managers. Quantifying the groundwater-use component for a groundwater model is a vital but often challenging endeavor. This dataset includes groundwater withdrawal rates modeled for the Ozark Plateaus aquifer system (Ozark system) from 1900 to 2010 by county for domestic water use. Public supply, non-agriculture, livestock, and agriculture...

Time-lapse DC resisitivity data were collected to monitor water table position during the 2015 Lower Coloradro River Pulse Flow. Resistivity data are sensitive to water-content change in the subsurface. DC resistivity data were collected at three transects. In the U.S., one transect was located parallel to the channel in the southern limitrophe reach nearby a streamgaging station. In Mexico, two transects were measured, one parallel and one perpendicular to the channel.

This point dataset contains water-level information concerning depth to water, potentiometric-surface altitude, and saturated thickness for the shallow groundwater system at selected well and borehole locations in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Depth-to-water data were compiled from measurements reported by the Colorado Division of Water Resources, U.S. Geological Survey, and Bureau of Reclamation. Potentiometric-surface altitude values were computed from the potentiometric-surface altitude raster dataset (potalt). Saturated-thickness values were computed from the saturated-thickness raster dataset (satthk). The U.S. Geological Survey prepared this dataset...

In 2019, the U.S. Geological Survey (USGS), in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and recurrence interval of streamflow needed to initiate bed movement of gravel-sized and finer sediment in a segment of the Colorado River in Colorado to better understand sediment movement and its relation to flow regimes of the river. Bed movement occurred more frequently and at lower streamflows from State Bridge to Catamount Bridge compared to the study area upstream from State Bridge. Two independent and complementary lines of evidence were collected to detect incipient bed movement. Two stationary hydrophone systems were installed on April 23, 2019 at the above...

The Escalante Watershed case study describes the application and integration of multi-scale geospatial data from the Colorado Plateau and Utah Landscape Assessment 2014 (Rapid Ecoregional Assessment or REA), Assessment, Inventory, and Monitoring (AIM), and Riparian Condition Assessment Tool (R-CAT) to help answer management questions. While REA provides broad-scale data and AIM provides field-scale point data, R-CAT, a geospatial tool designed at Utah State University, provides the middle ground reach-scale data. The Escalante watershed is a complex area with land managed by BLM, USFS, and NPS as well as privately owned land.

The Omnibus Public Land Management Act of 2009 (Public Law 111-11) was passed into law on March 30, 2009. Sub-title F of the law, also known as the SECURE (Science and Engineering to Comprehensively Understand and Responsibly Enhance) Water Act, calls for the establishment of a “national water availability and use assessment program” in the U.S. Geological Survey (USGS). The recommendation for a national assessment of the available water resources was driven by the lack of such an assessment since 1978. In fulfillment of the Act, the USGS developed the National Water Census (NWC), under the auspices of the USGS Water Availability and Use Program, and as part of that activity, among others, collected water withdrawal...

Locations of focused groundwater seepage to surface water are often hydrologically and ecologically important. Spatially focused or ‘preferential’ seepage can be identified as anomalous cold zones compared to warmer adjacent bank and surface water features (in summer). The temperature of deeper groundwater on Cape Cod is expected to approximate 11 °C year-round, yielding a relatively cold signature where groundwater emerges from the saturated sediment interface. Recent advances in thermal infrared imaging allow efficient real-time scanning for cold anomalies that may be associated with preferential seepage zones, and direct temperature measurements can be collected within the sediments of these zones to better capture...

This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for an average (or present-day) climate condition and 2017 land cover, as described in USGS SIR 2019-5064. The water-budget components for each model subarea were computed for a scenario representative of present-day climate conditions during 1978-2007 using a water-budget model developed by Johnson and others (2018). The 2017 land-cover map developed by Mair (2018) was used to define the land-cover conditions and the model subareas. The shapefile attribute information associated with each subarea (or polygon) present an estimate of mean annual rainfall, fog interception, irrigation,...

GPS data collection: GPS measurements were taken at 24 geodetic monuments during September 27-October 2, 2015. The GPS surveys generally followed established guidelines (Zilkoski and others, 1997), except that the data were processed with single-baseline, rather than multi-baseline, software. GPS measurements were recorded at the monuments on at least 2 different days during 1-hour observation periods. Of the 24 geodetic monuments, 7 were network control stations—DUNE, COCH, DEEP, CAHU, PAIN, C101, and G70; GPS measurements were recorded at these seven stations on 3 additional days during 6.5-hour (or longer) observation periods. InSAR data collection: The data set consists of twenty-four individual interferograms...

Hi-Desert Water District (HDWD) is constructing a wastewater treatment plant as part of a groundwater replenishment and reuse project (GRRP) in the east hydrogeologic unit (Nishikawa, and others, 2003) of the Warren Valley Basin (7-012) (California Department of Water Resources, 2016) in Yucca Valley, CA. The HDWD plans to use reclaimed wastewater for managed aquifer recharge by spreading treated wastewater into unlined ponds at the GRRP facility. Reclaimed wastewater will percolate through the unsaturated alluvium by gravity drainage through the unsaturated zone to the water table located about 370 feet (ft) below land surface (bls). As part of the cooperative efforts between the HDWD and the USGS, the electrical...
