The freshwater fish LA anglers actually chase. Florida-strain genes and a long local tournament history, especially at Castaic.

Weed lines, docks, timber, and drop-offs in reservoirs — Castaic, Pyramid, Puddingstone, and many urban lakes.
Statewide lakes: 12-inch minimum, five fish (T14 CCR §5.00). The 2026 freshwater booklet lists Castaic Lake at the same 12-inch minimum and five-fish limit, so the old 15-inch Castaic rule no longer applies. Pyramid and Puddingstone follow the 12-inch lake rule too. Read any on-site posting.
Largemouth bass are green to olive with a dark, broken stripe along the side. The upper jaw extends past the rear of the eye when the mouth is closed, which separates largemouth from smallmouth and spotted bass.
Largemouth are the main sport fish in the county's larger reservoirs, including Castaic Lake, Castaic Lagoon, Pyramid Lake, Puddingstone Reservoir, Santa Fe Dam, Legg Lake and Elizabeth Lake, and they live in many urban park lakes. They hold around weeds, docks, submerged timber, rocks and drop-offs.
Lakes are open all year. Spring spawning brings bass shallow, summer pushes them deeper or into shade during the day, and fall often brings active feeding as water cools.
OEHHA advisories for black bass vary by lake: Castaic Lake, 0 servings a week for women 18–49 and children and 1 for women 50+ and men; Pyramid Lake, 0 servings a week for women 18–49 and children and 1 for women 50+ and men; Santa Fe Dam Lake, 0 servings a week for women 18–49 and children and 1 for women 50+ and men; Magic Johnson Lakes, 0 servings a week for women 18–49 and children and 1 for women 50+ and men; Legg Lake, 1 servings a week for women 18–49 and children and 3 for women 50+ and men; Puddingstone Reservoir, 1 servings a week for women 18–49 and children and 2 for women 50+ and men; Castaic Lagoon, 1 servings a week for women 18–49 and children and 2 for women 50+ and men; Alondra Park Lake, 1 servings a week for women 18–49 and children and 2 for women 50+ and men; Kenneth Hahn (Gwen Moore Lake), 1 servings a week for women 18–49 and children and 2 for women 50+ and men. For lakes without site-specific advice, OEHHA's statewide lake advisory says women 18–49 and children should not eat black bass, and women 50+ and men should eat no more than 1 serving a week. Many local anglers release bass.
The statewide lake rule is a 12-inch minimum and 5 black bass per day. The 2026 freshwater booklet lists Castaic Lake under the same 12-inch, 5-fish rule. A license is required for anglers 16 and older.
Older guides list a 15-inch Castaic rule; the 2026 regulations set 12 inches. Castaic Lagoon is a different basin — check on-site posting.
