Rapid City, South Dakota is implementing lawn watering restrictions starting on April 1st, two months earlier than usual, due to low water levels at the Pactola Reservoir. The restrictions prohibit watering between 9am and 6pm daily and only allow odd-numbered addresses to water on odd days and even-numbered addresses on even days.
