The water gushed from a valve near the base of the Loveland Reservoir’s dam at 146,300 gallons per minute, cascading into the Sweetwater River below. The impressive sight near Alpine — which occurred, purposely, at 10:30 a.m. on Feb. 15 — marked the start of an ongoing transfer of water from the Loveland Reservoir to the Sweetwater Reservoir, where the water will be treated by the Sweetwater Authority and later supplied to the water agency’s customers in National City, Chula Vista and Bonita.
