GCD Panel - Management Strategies (Panhandle), Jim Conkwright
Groundwater Management Strategies For The High Plains of Texas Jim Conkwright General Manager High Plains Underground Water Conservation District No. 1 Lubbock TX TAGD Groundwater Summit August 29, 2012
High Plains of Texas• We live with drought on daily basis. – Agricultural, industrial, and urban water users continue to adopt conservation practices.• Agricultural irrigation only supplements rainfall. (Less pumping in wet years + more in dry years)• Reliance on water conservation plays key role in water planning.• GCDs in Ogallala region use similar strategies. – Allowable production rates. – Shared management plans/conservation strategies. – Water well spacing requirements.
Different Districts = Different Desired Future Conditions = Different StrategiesGCDs use a variety of tools in the toolbox to formulatewater conservation strategies to achieve DFCs.Adopted strategies based upon local decisions.

HPWD DFC and Management Strategies• DFC for Ogallala Aquifer is 50/50.• 50 % of saturated thickness in 2010 still in storage in 2060.• Strategies include: • Spacing rules • Allowable production rates (APR) • Water use reporting • Water banking • Public education/awareness
Take Home Points• Proactive management needed if sustainable use of water resources is to be achieved.• “One Size Doesn’t Fit All!”• GCDs must use different management tools as they formulate strategies for local management of aquifers.
