ES Comments on GMA-12 Proposed DFCs

UPDATE (7/23/2016):

Environmental Stewardship provided comments to the Lost Pines Groundwater Conservation District Board of Directors and the Groundwater Management Area 12 District Representatives at the July 20, 2016, public hearing.

ES urged the Board and GMA-12 to 1) adopt the Proposed Desired Future Conditions (DFCs). and 2) amend the adopting resolution to accurately state that the review process is not, and cannot be, completed until adequate tools and information are available, and therefore, the Proposed DFCs do not yet provide a balance between the highest practicable level of groundwater production and the conservation, preservation, protection, recharging, and prevention of waste  of groundwater in the management area as required by Texas law.

Though a great deal was accomplished during this second round of DFC review, and we applaud the much more open and transparent process, it is evident that a full and adequate consideration of several items was not possible because the tools, information, and time were not available to complete these tasks in compliance with Section 36.108(d). The considerations of critical concern to Environmental Stewardship, are (See Sections C, D and E of ES comments):

  • (4) other environmental impacts, including impacts on spring flow and other interactions between groundwater and surface waters, and
  • (7) the impact on the interests and rights in private property, including ownership and the right of management area landowners and their lessees and assigns in groundwater, and
  • balancing between conservation and development of these resources.

Since it is the duty of the groundwater conservation districts to protect the property rights of landowners like ES and others who want to conserve and preserve their groundwater in place for future use, non-commercial uses, sustainability, and  environmental considerations, we look to you, the Lost Pines District and Board, to adopt desired future conditions that truly balance between the conservation and development of groundwater resources (See Section A & B of ES comments).

The Districts and GMA-12 have recognized and acknowledged their responsibility and duty to balance the use of groundwater resources between developing and conserving the aquifer in adopting desired future conditions (See Section C, Consideration 7 of ES comments).

We also look to you to ensure that our concerns have been fully and adequate considered and that adequate and complete written responses are provided in the explanatory report demonstrating how our concerns were, or were not, incorporated into the finally adopted DFCs (See Sections A and B of ES comments).

The Simsboro Aquifer Water Defense Fund, League of Independent Voters of Texas, and Neighbors for Neighbors signed on in support of Environmental Stewardship’s comments.

ES comments on GMA-12 DFCs


Environmental Stewardship has but one interest in this GMA-12 DFC review process; to protect the integrity and functioning of the ecological systems that form the basis of the Colorado and Brazos river basins and the Carrizo-Wilcox and associated aquifers for current and future generations.

In conformance with the Conservation Amendment of the Texas Constitution, it is the duty of the Texas Legislature and Groundwater Conservation Districts to conserve and preserve the natural resources of the state — our groundwater, our rivers, our springs, and our ecosystems — by passing laws, rules, and for the purposes of this effort, adopting desired future conditions, that achieve a balance between conservation and development of those resources in perpetuity. To protect our aquifers as we found them while respecting the ownership rights of landowners. Though the ability to preserve an aquifer for future generations is not totally in our control — its rate of replenishment, and its hydrologic characteristics, are largely a function of Mother Nature and must be accepted and respected — development of an aquifer, and ultimate depletion of an aquifer and/or the surface water and ecosystems which depend on groundwater, is the voluntary human action in which we are currently engaged.
The essence of conservation and preservation of an aquifer resource is that the rate at which we deplete our aquifers must be in balance with the conservation of the aquifer. That the depletion not be driven only by the desire for development, against which we simply wait for damage to the aquifer’s sustainability before attempting to bring it back “in balance”. Only as a bright “conservation standard” describing a sustainable aquifer is established — an aquifer that is preserved in perpetuity — can we then determine how much of that aquifer we can develop in balance with the conservation standard. Conservation and protection of an existing aquifer for the common good of future generations must be the priority, not the development of an aquifer to satisfy every current and speculated human demand on it. Civilizations that have disappeared have failed to realize this distinction when they exploited natural resources.

ES recommends that the GMA-12 districts debate and adopt its own version of this conservation standard to guide in adopting desired future conditions during this cycle.
