Carrizo-Wilcox Aquifer Study

The Bureau of Economic Geology posted an overview of the Carrizo-Wilcox Aquifer study.

Each Water District completed a survey

Gonzales County reply to conservation and concerns questions:

The District (Gonzales Co) has two main concerns related to groundwater management and/or protection issues. The first concern is the economic and social consequences that the resulting managed available groundwater volume will have on existing well owners. Increased pumpage causes increased drawdown which requires existing well owners to lower pumps in wells or drill deeper wells. Lowering of the water table or artesian pressure also increases the power costs of raising the water to the surface. Permit applicants for large scale pumping projects are currently not required by Chapter 36 of the Texas Water Code to mitigate these increased costs on existing well owners.

The second concern is the inability of the District to reserve groundwater for future in-district growth. In the approved 2006 Regional Water Plan our District is currently targeted for more water in the Carrizo Aquifer than is available from the District. This indicates that the entities with water management strategies in the Regional Water Plan have plans to permit all of the available Carrizo Aquifer water in the District which leaves no water for future in-district growth. The current system has the District supplying all of its available groundwater to cities along the I-35 corridor for their future growth while leaving none available in the District for future growth.
