Lopez Lake

Ten miles east of Arroyo Grande, Lopez Lake’s 22 miles of shoreline and warm waters provide a hub of outdoor family fun.. The recreation area’s 4,200 acres of open space encourage camping, hiking, mountain biking, and riding horseback. For thrill-seekers, the Lopez Lake Recreation Area also offers an adventure ropes course and zip lines, as well as a family waterslide park.


The Chumash once hunted and fished throughout the canyons that surround Lopez Lake. Ranchers and homesteaders followed, growing and harvesting crops to support the California Mission in San Luis Obispo. In 1969, engineers built the Lopez Dam and Lopez Lake was the natural result. Today the lake holds nearly 7 million cubic meters when full, and is a destination for outdoor and wildlife enthusiasts.

Water Activities

With an average year-round temperature of 79 degrees F year-round, Lopez Lake makes an ideal spot for water play. Rent a powerboat or launch your own from the marina, then cruise out for fishing, water skiing, and wakeboarding. Visitors also come to Lopez Lake to Jet Ski, stand-up paddleboard, windsurf, sail, and kayak. Or, for the simplest way to enjoy Lopez Lake, take a dip, a dunk or a swim in its refreshing blue waters.

Lopez Lake Fishing

With 450 surface acres and comfortable year-round conditions, Lopez Lake makes for a great fishing destination. Find rainbow trout (stocked during winter months), as well as largemouth bass, crappie, red-eared sunfish, catfish, and bluegill in these clean waters. Note that while 12 inches is the minimum bass size, most are under 4 pounds. Cast off near coves, points and underwater structures, as these are common fish habitats. For complete fishing regulations and a planting schedule, check the California Department of Fish and Wildlife website. The F dock, beside the Lopez Lake store, is a great starting point for first-timers, as all species can be caught there. Find a fish cleaning station beside the store, too.

For a day on the water, head to the Lopez Lake Marina to rent fishing boats, fishing poles and more. The Marina also carries bait and tackle, and sells fishing licenses.
