This region has always been shaped by water. Early settlers followed the post oak trees native to the ecoregion, tracking their deep taproots as a sign of reliable groundwater below the surface.

As communities developed, water also played a central role in Milam County’s industrial boom, supported by wells and reservoirs like Alcoa Lake.

Today, that connection runs even deeper. Both Burleson and Milam counties sit above a unique system of eight aquifers. More than 99% of Burleson County’s water supply comes from groundwater - supporting homes, farms, businesses, and growing communities.

From ranches and football fields to weekends spent at Lake Somerville with kolache in hand, understanding these surface and groundwater systems helps tell the story of Post Oak Savannah itself.
