Swimbait Fishing on Millerton Lake
Millerton Lake · California · West
Millerton Lake sits at the base of the Sierra Nevada foothills northeast of Fresno, formed by Friant Dam on the San Joaquin River. The reservoir is defined by steep rocky canyon walls, submerged points, and hard-bottom structure rather than grass or timber — clarity often runs 10–20 feet in cooler months and tightens toward the upper arm during late-summer drawdown. Spotted bass are the dominant gamefish, though largemouth hold in the shallower cove systems and stripers make seasonal pushes upriver toward the dam tailrace.
Covers everything from 3" paddle tails to 10"+ hard-body glide baits. Paddle tails on a swimbait head cover water efficiently; large glide baits and jointed hard swimbaits target trophy fish specifically. Swimbait fishing rewards patience — fewer bites, but the bites that come are often the biggest bass of your life.
Swimbait Setup for Millerton Lake

Seasonal Tactics on Millerton Lake
Lake: Spotted bass and largemouth stage on rocky points and secondary channel swings in 8–18 ft as water temps climb through the low 60s — finesse jigs and drop shots on 45-degree rock transitions produce the most consistent bites from late February through April.
Swimbait: Post-spawn giants recovering — slow roll a big paddle tail along the first drop off beds.
Lake: Drawdown pushes fish deep by July; spotted bass school on main-lake points and submerged ledges in 25–45 ft, and a drop shot or swimbait on forward-facing sonar becomes the dominant method as surface temps push into the mid-80s.
Swimbait: Early morning on main lake points. Slow-roll a 6"+ swimbait along ledge faces at dawn.
Lake: Cooling temps in October and November pull spotted bass back into the 10–20 ft range on rocky cove points; shad migrations concentrate fish near the upper river arm, and topwater walking baits like a Spook Jr. draw violent strikes during low-light windows.
Swimbait: Best season — bass targeting large shad. Match the size of forage exactly. Shad colors.
Lake: Water clarity peaks in winter and the spotted bass bite slows but doesn't die — a Megabass Vision 110 on a long pause or a Ned rig on hard bottom in 15–25 ft will pick off lethargic fish; striper action near the dam tailrace can be productive on cold, clear mornings.
Swimbait: Slow down the retrieve dramatically. Big fish are lethargic but will eat a slow-moving large profile.
Best Conditions
Clear water, trophy fisheries, post-spawn and fall, shad migrations, open water and around structure, dawn and dusk
Slow down more than you think. Most anglers retrieve swimbaits too fast. A barely-moving bait triggers more bites from big, selective fish.
