Groundwater / Water Wells
Water wells here tap the Ogallala Aquifer — and need a permit
Nearly all water in Sherman County comes from the Ogallala Aquifer, and the North Plains Groundwater Conservation District regulates who can drill a well and how much water they can use.
Sherman County sits above the Ogallala Aquifer, one of the largest underground water sources in North America. The North Plains Groundwater Conservation District (NPGCD) manages this resource for the northern Texas Panhandle, including Sherman County. Before anyone drills a water well here, they must contact the district.
Small domestic or livestock wells that produce less than 17.5 gallons per minute are considered exempt — they still need to be registered, but do not need a full permit. Larger wells require a Well Construction Permit, which costs $1,000 and takes about seven business days to process. The district office is in Dumas (806-935-6401) but covers Sherman County. Contact them before you hire a driller.
