In 2004, a hydrologic water-budget analysis was conducted and the results published in the report, Water-Budget Analysis of Medina and Diversion Lakes and the Medina/Diversion Lake System, With Estimated Recharge to the Edwards Aquifer, San Antonio Area, Texas (SIR 2004-5209)(Slattery and Miller, 2004). This data release contains the hydrologic water-budget data used in a reanalysis of the data as well as the results of the reanalysis. The hydrologic water-budget data used was derived from selected columns of data found in table 5 of the report. The columns of selected data include the time period in which the data were collected, the number of days used to obtain the average groundwater outflow, the standard deviation...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...

This dataset represents an estimated representation of net annual recharge of surficial aquifers in Wyoming from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 500 meter cell size. For more details about this dataset, please refer to this report: Hamerlinck, J.D. and Arneson, C.S., editors, 1998, Wyoming Ground-Water Vulnerability Assessment Handbook: Volume 1. Background, Model Development, and Aquifer Sensitivity Analysis: Wyoming Geographic Information Science Center Publication WyGISC 98-01-1, University of Wyoming, Laramie, WY.

Categorical classification of groundwater age based on concentrations of tritium (3H) in groundwater can provide useful information for the assessment and understanding of groundwater resources. These data present a three-part groundwater age classification system for the continental United States based on tritium thresholds that vary in space and time: modern (recharged after 1952), if the measured value is larger than an upper threshold; premodern (recharged prior to 1953) if the measured value is smaller than a lower threshold; or mixed if the measured value is between the two thresholds. Inclusion of spatially-varying that vary geographically on the basis of the location of the sample rather than a single threshold...

This dataset contains environmental tracer data from surface water and groundwater samples collected by the U.S. Geological Survey in Redwell Basin, an alpine watershed in the Elk Mountains near the town of Crested Butte, Colorado. The basin is underlain by interbedded shale and sandstone that have been variably hydrothermally altered and silicified by local magmatic intrusions. Samples were collected from 2017 to 2019 from bedrock monitoring wells completed at multiple depths, shallow hand-installed piezometers and mini boreholes, springs, mine adits, and streams. The tracer data include stable isotopes of water (oxygen-18 and deuterium), tritium, dissolved noble gases (He, Ne, Ar, Kr, Xe, and helium-3/helium-4...

This archive documents 1) mean monthly recharge estimated for three watersheds (Coal Creek, Boise Creek, and Scatter Creek) by a Soil Water Balance (SWB) model of the Puyallup and Chambers-Clover Basins in Pierce and King Counties, Washington and 2) the spatial extent of the Coal Creek, Boise Creek, and Scatter Creek watersheds.

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

The California Basin Characterization Model (CA-BCM 2014) dataset provides historical and projected climate and hydrologic surfaces for the region that encompasses the state of California and all the streams that flow into it (California hydrologic region ). The CA-BCM 2014 applies a monthly regional water-balance model to simulate hydrologic responses to climate at the spatial resolution of a 270-m grid. The model has been calibrated using a total of 159 relatively unimpaired watersheds for the California region. The historical data is based on 800m PRISM data spatially downscaled to 270 m using the gradient-inverse distance squared approach (GIDS), and the projected climate surfaces include five CMIP-3 (GFDL,...

This draft dataset represents an estimated representation of net annual recharge of surficial aquifers in Wyoming from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 100 meter cell size.

This dataset represents an aquifer sensitivity rating for naturally occurring recharge in the State of Wyoming. This dataset is specifically to be used within a DRASTIC-type aquifer sensitivity/vulnerability analysis. The dataset is in raster format with 100 meter cell size.

Problem - The Town of Caroline needs geohydrologic data in two major valley-fill aquifers within the town in order for planners to develop a strategy to manage and protect their water resources. Interest in the interaction between ground water and surface water has increased in recent years as a result of widespread concerns related to water supply. The need to better understand how the development of one water resource affects another will increase as development in Tompkins County intensifies. Upper Sixmile Creek/West Branch Owego Creeks valleys and Lower Sixmile Creek/Willseyville Creek valleys in the Town of Caroline were selected to be studied because they are undergoing increasing development; and most people...

IMPORTANT NOTE: A more recent version of this data release is available from this link. The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for recreational activities, businesses, and downstream users, and provide habitat for several threatened or endangered species. The areas pertinent to the recharge process are the catchment area and the recharge zone. The catchment area...

This dataset includes 800m resolution long-term average estimates of evapotranspiration (ET), quick-flow runoff, and recharge within a closed water budget over the 2000-2013 time period and annual estimates for the individual years. It also includes other supporting data associated with the publication of these estimation methods in a concurrent journal article. These estimates were developed with new empirical regressions for (1) quick-flow runoff data generated using data points from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1434 gaged watersheds, as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO); and (2) long-term...
