As of Thursday, July 22, about half of Polk County is experiencing severe drought and the rest of the county is experiencing extreme drought. Most of Red Lake County is experiencing extreme drought.

Many domestic wells within this area pump groundwater from the shallow aquifers located within 100 feet of the ground surface. Wells
