Dispersal, establishment, and spread of aquatic invasive species such as the zebra mussel (Dreissena polymorpha) can be influenced by riverine velocities and volumetric flows in invaded lake-stream ecosystems. Zebra mussels, which have a planktonic larval form (veliger), disperse rapidly downstream from a source population. Concentrations, dispersal, and body conditions of zebra mussel...

Hydrologic water-budgets were calculated for the Medina and Diversion Lake system near San Antonio, Texas for periods between March 1955 and June 2002. The hydrologic-budgets were calculated from daily hydrologic data that included precipitation, evaporation, streamflow, and change in reservoir storage. The residual of the hydrologic budgets represent ground-water outflow from the Medina...

In February 2017, the Grand River Dam Authority filed to relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission. The predominant feature of the Pensacola Hydroelectric Project is Pensacola Dam, which impounds Grand Lake O the Cherokees (locally called Grand Lake) in northeastern Oklahoma. Identification of information gaps and assessment of project...

To help characterize the groundwater system at Homestake Mining Company Superfund Site near Milan, New Mexico, the U.S. Geological Survey collected borehole geophysical and groundwater-quality data in cooperation with the U.S. Environmental Protection Agency during JulyOctober 2016. The following borehole geophysical data were collected from wells at or near the Homestake Mining Company...

The U.S. Geological Survey in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset shows compaction values of subsurface sediments (mostly in the fine...

The transboundary Mesilla Basin/Conejos-Mdanos aquifer system was identified as one of the priority transboundary aquifer systems for additional study by the United States and Mexico U.S.-Mexico Transboundary Aquifer Assessment Act of 2006. One of the largest rechargeable groundwater systems by total available volume in the Rio Grande/Rio Bravo del Norte Basin region of the United States...

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...
