Data

This USGS data release presents tabular data and photos used to determine (1) the duration of flow, subsurface temperature, and concurrent infiltration along an ephemeral channel and (2) vertical change of soil moisture, texture, and pore-water chemistry in the unsaturated zone at selected locations. The data were collected to investigate the feasibility of managed aquifer recharge (MAR) for aquif

This USGS data release presents Model Archive Summaries (MAS) and tabular calibration data used to develop surrogate regressions to estimate fine sediment particles flowing into Lake Tahoe. Fine sediment particles in the size range of 0.5 to 16.0 micrometers (μm) represent the primary size range of suspended sediment responsible for clarity reduction in Lake Tahoe. Models will be used to

Stakeholder science needs were determined by reviewing more than 200 recently published literature items and web pages from Colorado River Basin (CRB) stakeholders. These stakeholder communications were used to characterize over 400 stakeholder science needs by reviewing their priorities, strategies, issues, missions, and concerns related to drought in the CRB. Members of the CRB Integrated Scienc

This U.S. Geological Survey (USGS) data release consists of a spreadsheet presenting high-frequency water levels in feet below a measuring point (MP) at Devils Hole in Nye County, Nevada. Water-level data are collected at USGS site 362532116172701 by the National Park Service, using a data logger programmed to collect water-level every 15 minutes or every 5 seconds when a water-level change greate

This U.S. Geological Survey data release consists of a tabular dataset containing stream temperature data. Data were collected every 12-hours from 15 sites in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The sites were established by the Bureau of Land Management - Winnemucca District Office in 2017. The data release includes tabular dat

Two MODFLOW 6 (version 6.2.1) models of hypothetical stream-aquifer systems are presented for the demonstration and utility of the Water Mover (MVR) Package available only with MODFLOW 6. Using a generalized approach, MVR facilitates the transfer of water among many arbitrary combinations of simulated features (i.e., pumping wells, stream, drains, lakes, etc.) within a MODFLOW 6 simulation. In th

The USGS developed an integrated river operations-groundwater model using GSFLOW and MODSIM GSFLOW to simulate streamflow derived from snowmelt, the distribution of surface water based on the existing prior appropriations water doctrine, supplemental pumping in response to surface water shortfalls, and the resulting surface water-groundwater interactions in the Carson Valley in California and Neva

This USGS data release presents data used to interpret aquifer tests and ultimately characterize the hydraulic properties of carbonate-rock and basin-fill aquifers near Long Canyon, Goshute Valley, northeastern Nevada. The supplemental data consist of 2 child items and 3 attached appendix datasets. The child items are: (1) 2011?2016 Single Well Aquifer Tests: Pumping Schedules, Water-Level Data i

This U.S. Geological Survey data release is a spreadsheet containing soil-profile measurements of ambient spring and fall water-potential and water-content conditions, and physical and chemical properties for four mine sites, Mohave County, Arizona, April and November 2018. The four mines sampled in both April and November were Kanab North (native soil and reclaimed soil), EZ2 (native soil), Arizo

This vector line dataset represents the lower Las Vegas Wash study area. Surface-water trace was digitized onscreen from Landsat8 and ESRI World Imagery. The trace is used in an accompanying surface-water study to evaluate discharge gains and losses at selected locations in the Lower Las Vegas Wash.

A three-dimension groundwater-flow model (MODFLOW-2005) was developed to improve understanding of groundwater flow and pumping effects near the Long Canyon Mine in Goshute Valley, northeastern Nevada. Bulk hydraulic properties of carbonate rocks and basin-fill aquifers were characterized by simultaneously interpreting steady-state flow during predevelopment conditions and changes in groundwater le

This USGS data release consists of polygons representing Gumboot Lake extents from the report Effects of ground-water development on the water regimen of Paradise Valley, Humboldt County, Nevada, 1949-1968 and Hydrologic Reconnaissance of the Tributary Areas (Nevada Department of Conservation and Natural Resources Water Resources Bulletin 39). There are two datasets containing four different exten
