Your watershed
Town Lake-Colorado River
A watershed is the land area where rain and streams drain toward a shared outlet. It helps explain natural water conditions, but it may not match the area supplying your tap.

Groundwater near Austin
Aquifers can supply water; monitoring wells measure water levels at individual sites. One well does not describe an entire aquifer or your household well.
Groundwater sources
No aquifer source identified
The supply records do not name an aquifer. Groundwater may still be present.

Reading well data
What well measurements can tell you
A well’s water level does not tell us how much water an aquifer holds. Pumping totals alone do not show depletion, and a surface map does not show the aquifer’s full underground extent. To understand water quality in a private well, use tests from that well and local guidance.
