摘要

Texas faces a number of issues in an attempt to balance the water needs of a growing population while at thensame time trying to conserve its water resources. Some of these issues include infrastructure improvements andnprovision of new supplies, changing patterns of use, water marketing and aquifer depletion. With aquifersnproviding 60% of all the water used in Texas, protecting and keeping these sources viable in the future is a keynpriority in addressing the state’s water issues. With the state’s emphasis on local control and the existence ofnbetween 80 and 90 groundwater districts state-wide, this research seeks to answer the question “Do groundwaterndistricts in the State of Texas make a difference in groundwater depletion?” We use panel data from a set of 8,110nobservations in a fixed effects regression to help us answer this question. We find evidence to suggest thatngroundwater districts do make a difference. After taking into consideration a couple of potential threats to validity,nwe run our model on a per district basis and by groundwater management areas. We also run it on a per aquifernbasis and compare results with recommendations in the 2007 Texas Water Plan as a reality check. If wensuccessfully answer the question that districts do in fact matter, the next logical step is to investigate what it is thatndistricts do that makes a difference.
