Over the last century, aquifers in this area have lost between 300 and 400 feet, leaving some of the land to collapse. Subsidence is known to have occurred in the southern part of Montgomery County based on monitoring and long-term surveying of land surface. As a result of Senate Bill 1336 in the 84th Legislature, the Edwards Aquifer Authority is no longer required to submit management plans to the TWDB. <>stream The Lone Star GCD has studied the Gulf Coast Aquifer for a decade and confirmed the reports of many local water suppliers, which state that water levels in the countys aquifers have declined at an alarming rate as a result of deficit pumping. Now Hiring! The Lone Star Groundwater Conservation District in 2012 purchased six Periodically Accessible Monitors (PAMs), which are specifically designed to detect subsidence.
