Flow pattern in regional aquifers and flow relations between the lower Colorado River valley and regional aquifers in six counties of southeastern Texas

Woodward, D. G.

Abstract:

The 318-river-mile reach of the Lower Colorado River from Mansfield Dam near Austin, Texas, to the Gulf of Mexico is underlain directly or indirectly by six regional aquifers--the Trinity, Edwards, Carrizo-Wilcox, Queen City, Sparta, and Gulf Coast. The Trinity aquifer is further subdivided into the lower Trinity, middle Trinity, and upper Trinity aquifers. Generalized potentiometric-surface maps of each regional aquifer show the groundwater flow pattern near the river valley. Each regional aquifer discharges water to the lower Colorado River valley, particularly in the outcrop area of each aquifer. Only the Gulf Coast aquifer in central Wharton County appears to be recharged by water in the river valley. A summary map shows those subreaches of the lower Colorado River that gain water from the aquifers and the subreaches that lose water to the aquifers. (USGS)
