Around 8 p.m. on the Fourth of July, Borger PD began receiving 911 calls regarding a man having difficulty swimming across Sanford-Yake Cove. Witnesses said that Charles Johnston, 21, started to swim across the cove to meet up with his brother and friends, who were camping in South Canyon, when he started to have problems swimming. He began yelling for help and then went under the water. Within minutes of receiving the call, Texas Parks and Wildlife officers launched a boat and started to search the cove. National Park Service rangers arrived minutes later and started witness interviews. Efforts to locate Johnston’s body proved fruitless that night and the search was suspended after midnight. Searching continued Thursday morning with the assistance of Texas Parks and Wildlife officers, Amarillo Police Department divers, and Clarendon Fire Department divers. Johnston's body was recovered early on the afternoon of July 5th. Additional assistance came from the Hutchinson County Sheriffs' Department and Fritch EMS and Fire Department. Supervisory ranger Dale Culver was the incident commander.
