Conjunctive Management of the Edwards Aquifer and Connected Surface Streams in South Central Texas

by John H. Specht, Guadalupe-Blanco River Authority, United States,

Document Type: Proceeding Paper

Part of: Optimizing the Resources for Water Management


The Edwards Aquifer is a long, narrow conduit through which water moves underground across parts of South Central Texas. Increased use of water from the Edwards Aquifer has been substantial as regional population has grown and irrigation has increased. Current levels of diversion from the Edwards Aquifer can not be sustained if another drought occurs equal to or greater in severity than the drought of record. It is essential that uses of water from the Edwards be regulated in conjunction with regulation of use of water from the Guadalupe River. Regulation of the Edwards should begin with an adjudication of all claims of rights to divert water from the Edwards. To the extent that the Edwards can not meet all current or future needs, water users will find it necessary to seek supplemental sources of water.
