Recent rains have helped water levels at Lake Horton increase by more than six feet, but the lake remains 10.1 feet below full pool thanks to the longstanding drought. Lake Horton is the county’s southernmost water reservoir and is partially filled by withdrawing water from the Flint River, which didn’t happen as often because of low flows on the Flint due to the drought, water system officials have said.
