Closed for eight years because of a dam-raising project, the San Vicente Reservoir reopened to the public Wednesday. The city of San Diego-owned body of water in the East County will be available for boating and fishing. The marina will include a six-lane boat ramp, concessions stand to rent boats and supplies, parking lot for more than 300 vehicles and a picnic area. “This is an exciting day for anglers, water sport enthusiasts, boaters and San Diego families,” Mayor Kevin Faulconer said.
