Water levels in 93 wells completed in the Wood River Valley aquifer system were measured during October 22–24, 2012; these wells are part of a network established by the U.S. Geological Survey in 2006. Maps of the October 2012 water-table altitude in the unconfined aquifer and the potentiometric- surface altitude of the confined aquifer have similar topology to those on maps of October 2006 conditions. Between October 2006 and October 2012, water-table altitude in the unconfined aquifer rose by as much as 1.86 feet in 6 wells and declined by as much as 14.28 feet in 77 wells; average decline was 2.9 feet. From October 2006 to October 2012, the potentiometric-surface altitude in 10 wells completed in the confined aquifer declined between 0.12 and 20.50 feet; average decline was 6.8 feet.

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 water‐level altitudes and water‐level changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas.This dataset shows current‐year (2015-2016) water‐level altitudes for each aquifer, 5‐year (2011‐16) water‐level changes for each aquifer, long‐term (1990‐2016 and 1977‐2016) water‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2016) water‐level change for the Jasper aquifer. For the 1‐year (2015-16) water‐level changes, data were computed as the difference in water‐level altitude at each point (well) for which a water‐level measurement was made in 2015 and 2016. Five‐year (2011‐16) water‐level changes were computed the same as for the 1‐year water-level changes; the difference in water‐level altitude at each point for which a water‐level measurement was made in 2011 and 2016. The water‐level measurements in the dataset are built upon and stored in the National Water Information System: Web Interface, groundwater information, field measurements website located here: http://dx.doi.org/10.5066/F7P55KJN This site is a publicly available, searchable, online database of water information.

This point dataset contains estimates of aquifer transmissivity and hydraulic conductivity at selected well locations in the Lost Creek Designated Ground Water Basin, Weld, Adams, and Arapahoe Counties, Colorado. This dataset also contains hydrologic information used to estimate transmissivity from specific capacity at selected well locations. Data were compiled from published reports, consultant reports, and from well-test records on file with the U.S. Geological Survey and Colorado Division of Water Resources. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Geological Survey and the Lost Creek Ground Water Management District.
