Jacob’s Well is an artesian spring that emerges from the Trinity Aquifer to form the headwaters of Cypress Creek that flows into the Blanco River. During periods of drought, this river plays a vital role in recharging Barton Springs. Over the course of 3 months, water slowly travels down the Blanco to the Edwards Aquifer recharge zone to surface in Barton Springs.

Wimberley Valley relies on groundwater from the Trinity Aquifer for water supply. Water conservation ensures that all users including humans and ecosystems have enough water, especially during drought conditions.
