Kasmarek, Michaela R. Johnson, and Jason K. Ramage 2013 Information regarding water resources in Texas is available at http://tx.usgs.gov/ EXPLANATION Line of equal water-level rise—Interval 20 feet Line of equal water-level decline—Interval 20 feet Line of zero water-level change Updip limit of Jasper aquifer (Baker, 1986; University of Texas, Bureau of Economic Geology, 1968, 1974) Boundary of study area -20 0 Note: This change map was created by contouring the set of mapped point values computed as the difference in water-level altitude at each point (well) for which a water-level measurement was made in 2013 and 2008 (Kasmarek and Houston, 2008, sheet 12). The area of water-level change shown is based on availability of water-level data from 2008.
