The U.S. Geological Survey (USGS), in cooperation with the Harris‐Galveston Subsidence District, City of Houston, and the Fort Bend Subsidence District, produced a dataset through 2023 of compaction values in the Chicot and Evangeline aquifers in the greater Houston area, Texas. This dataset contains compaction values associated with subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously using analog technology. There are 14 extensometers at 12 locations (a pair of extensometers are installed at different depths at 2 of the 12 locations). Of the 14 extensometers, 13 were activated...

Please note: a more recent version of this dataset is available. Users are strongly advised to access the newer version of the dataset at https://doi.org/10.5066/P9YGUE2V. 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-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously by using...
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.
