The U.S. Geological Survey (USGS) 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 groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset shows current‐year (2018) groundwater‐level altitudes for each aquifer, 5‐year (2013‐18) groundwater‐level changes for each aquifer, long‐term (1990‐2018 and 1977‐2018) groundwater‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2018) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements...

This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas for 2019. The U.S. Geological Survey prepared this dataset in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to information regarding depths to groundwater in the region. All of the data in this dataset were collected from December 2018 through March 2019 and are stored in...

This dataset documents for 2018 the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. The U.S. Geological Survey prepared this dataset in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to accurate, impartial, scientific information regarding the depth to groundwater in the region. All of the data in this dataset were collected from December 2017 through March 2018 and are stored in the National Water...
Water Resources Mission Area - Social & Economic Drivers Program
​The Water Resources Mission A​rea - Social & Economic Drivers Program provides improved understanding of the impacts and interaction of socioeconomics and water availability. Research focuses on improved understanding of socioeconomic influence on water demand, use, and movement regionally; as well as National drivers to improve the ability of the National Water Census to forecast availability under a variety of conditions. This Sciencebase community will be a space for projects within the Social & Economic Drivers Program to store, manage, and share data.

In late August and early September 2017, Hurricane Harvey made landfall on the southeastern coastline of Texas and produced a record amount of rainfall, leading to widespread flooding. From August 25 through September 1, 2017, some areas in southeastern Texas received more than 60 inches of rain with large areas receiving at least 40 inches of rain. Hurricane Harvey was the largest rainfall event in United States history in terms of spatial extent and rainfall totals since rainfall records began in the 1880s (Watson and others, 2018). The five most heavily flooded river basins in Texas during this storm included the Brazos River, where the U.S. Geological Survey (USGS) collected water-quality samples at the Brazos...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
