Why Now
Maintaining healthy and sustainable aquifers is very important for all residents of Williamson County. Our aquifers feed the springs and creeks that make the Hill Country such a beautiful
place, and without groundwater many of the streams and springs would cease to exist. As aquifers become depleted and groundwater levels decline, so do our property values and the economic viability of future growth and development for the area. With effective groundwater management strategies we can work to ensure that residents continue to enjoy the beauty and benefits that healthy aquifers provide.

The Trinity Aquifer
If you are in Western Williamson county then you very likely have a well as your water supply. That well gets its water from the Trinity Aquifer.
The Trinity Aquifer is a major aquifer that extends across much of the central and northeastern part of the state - sixty-one counties contain the aquifer. It is one of the most extensive and highly used groundwater resources in Texas.
Unlike the Edwards, the Trinity Aquifer recharges very slowly. Only 4-5% of water that falls as rain over the area ends up recharging the Aquifer, and water also moves through the Trinity much more slowly than through the Edwards. The Trinity contributes a significant amount of water as recharge for the Edwards.
Depletion of the groundwater the Trinity Aquifer supplies will eventually lead to the drying up of creeks, springs, wetlands, and of course - your well.
