Salado Creek Springshed
Springsheds are the areas where the groundwater flows to the spring discharge point similar to that of a watershed for a stream. These may include areas that do not receive precipitation recharge and may include areas beyond the outcrop. Springsheds also may be only subsets of the aquifer recharge area as seen in the image below. Finally, springsheds may encompass different areas under different flow conditions.
Above is a preliminary springshed drawn from groundwater contours. The general idea is that water recharging the aquifer within the springshed should flow to the springs and water outside the springshed would not flow to the springs. The accuracy of the springshed boundaries is directly related to the density and quality of the groundwater level data available.
