Water Wells and the Ogallala Aquifer in Dallam County

The Ogallala Aquifer is the main water source for the Texas Panhandle. It underlies all of Dallam County and supplies water for homes, livestock, and irrigation. The aquifer has been declining for decades due to heavy farm use. In some parts of the High Plains, water levels have dropped more than 300 feet over 50–60 years.

Before drilling a new well in Dallam County, you need a permit from the North Plains Groundwater Conservation District (NPGCD). The district requires all wells to be registered — even small domestic or livestock wells that are exempt from full permitting. Well construction permits cost $1,000 and are valid for 150 days. You can reach the NPGCD at 806-935-6401 or visit northplainsgcd.org. The Texas Water Development Board tracks aquifer levels statewide.
