At the heart of Castro Valley sits Lake Chabot, a 315-acre drinking-water reservoir surrounded by miles of parklands and walking trails. At the marina, Lake Chabot Fishing Outfitters provides a complete assortment of bait and tackle, along with rod and reel rentals, boat rentals, and a café stocked with breakfast and lunch. Depending on the season, anglers can try different fishing methods to track down their desired targets. In the fall through the spring, spoon and fly fishers often reel in hungry trout, and summertime anglers are often successful with catfish, crappies, bluegill, and largemouth bass.
