Who We Are

The Lone Star Groundwater Conservation District (LSGCD) strives to ensure a supply of clean, affordable water for the future of Montgomery County, one of the fastest-growing counties in the country, with a population expected to exceed one million in just 25 years. Every residence and business needs water in some capacity and the District works to manage the amount of groundwater taken from below the surface on an annual basis.

The concept of groundwater management is as simple as balancing a checkbook – we must guard against pumping more groundwater than is replenished. However, the application is tricky because a number of unpredictable factors, including periods of drought, come into play.

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 county’s aquifers have declined at an alarming rate, the result of deficit pumping. The District’s vision is to manage the groundwater resources so that, in the near future, the amount of groundwater produced from the Gulf Coast Aquifer is no more than the average annual effective recharge to the Gulf Coast Aquifer System. Only upon achievement of this equilibrium will the water resources for Montgomery County be managed on a truly sustainable basis.

In accordance with its mission, the District has taken the following steps:

  • Calculated the amount of water the Gulf Coast Aquifer can yield in Montgomery County – 64,000 acre-feet (about 21 billion gallons) on a sustainable basis

  • Calculated the Total Qualifying Demand of large-volume users. Current use of that demand is some 25 billion gallons, far exceeding the sustainable level

  • Called on large-volume users to create plans for alternative water supplies and conservation; conservation, combined with the use of water from Lake Conroe, appear to be the most cost-effective options

  • Continues to work with all permit holders and stakeholders to ensure a sustainable, cost-effective water supply is available for current and future needs

  • Continues to seek and analyze new data

The District is bound by Chapter 36 of the Texas Water Code. One of the many ways the District carries out its mission and the powers and duties provided by Chapter 36 is through the creation of District rules. A major aspect of the District’s rules is its permitting program, which is carried out through well registration and permitting. For more information on how the District’s well registration and permitting program please see our Permitting page.


The mission of the Lone Star Groundwater Conservation District is to manage and protect the groundwater resources of Montgomery County and to work with others to ensure a sustainable, high-quality, and cost-effective water supply for current and future needs.
