Florida-strain largemouth bass are king at Lake Amador. More big bass per acre of water come from Amador than from any other lake Northern California. There are many 10 pound-plus fish landed each season. Lake Amador, planted in1969, was one of the first Northern California lakes to get Florida-strain stock.
It is rich in nutrients so the bass thrive and grow rapidly. March, April and May are the prime times for big bass. That’s when they come up to the shallows and move into the covers to spawn.
Popular lures in spring include spinner baits, cranks baits and plastic worms. Salt and pepper grubs and Pig ‘n Jigs are also winners. Bass seem to strike worms short, so use a four incher to insure a higher percentage of hook-ups.
Live nightcrawlers on a sliding sinker rig also score. Summertime bass action is in deeper water, except late in the evening or under a full moon. Evening top-water action can be fantastic on Zara Spooks, Hula Poppers,
Rebel Pop-R’s etc. bass anglers fish all night when the moon is full in spring and summer. They work the shoreline in coves and off points with surface plugs. Strikes are savage surface explosions.
Rainbow trout up to 5 pounds have been taken at Amador. Most catches are stocked fish in the ;12 to 15 inch range, but some larger holdovers are present. Popular spots include the first come near the dam off the dock and at any lake inlet that is running. Most anglers anchor and first bait in those inlets in the late winter and spring.
Trollers work the surface in the cooler months, but move deeper as June approaches. Trouting at Amador will improve even more as the lake expands its rearing ponds for fish in the 3 to 4 pound range.
Winter and spring anglers work the top 15 feet of water, while summertime trollers search deep, cool water in the 30 to 45 foot range by the dams, and up the middle of the lake and the Jackson arm. Salmon egg/marshmallow combos, Rooster Tails and Mepps work well. Trollers use Triple Teasers, Kastmasters, Needlefish and Nightcrawlers behind flashers.
In March, crappie start biting, and it gets real good in April, May and June along the shorelines, Fish range up to 2 to 3 pounds. Live minnows work, but mini-jigs in yellow or red and white are the top fish catchers.
Keep the jig moving right off the bottom. Hits often occur on the drop. The redear sunfish and bluegill bite come on strong in June and July in the brushy areas of the lake. Anglers take them with red worms or meal worms under a bobber.
While many anglers have concentrated on bass, those going after channel and blue catfish at Amador have also been doing well. Action usually begins as early as April on cats up to 20 pounds. But most of the cat fishing activity takes place in the summertime. Chicken livers and anchovies are the bait of choice at Amador.
The best action takes place after dark along the face of the dam and in the coves along the campgrounds. Anglers keep their reel bails open, and let the cats take out as much as 20 feet of line before setting the hook.
The Florida-strain largemouth bass at Lake Amador cycle through distinct seasonal behavior, transitioning from deep post-spawn recovery in winter to aggressive staging along shallow flats by late February as forage density increases and clarity improves. As California bass fishing pros know, pre-spawn activity concentrates under wind-blown banks where baitfish converge, and anglers exploit this by targeting the lead-up period with precise presentation to trigger short-strike aggression while their crews monitor sonar and adjust drift speed.
During the spawn window, males patrol nests in 3 to 8 feet, holding parallel to emergent vegetation, while females repeatedly sweep the same corridors and will chase reaction baits before settling to guard fry and occasionally producing double-digit aggressive charges. Post-spawn the big trophy bass move back to deep rock humps and transition to slow rolling swimbaits or drop-shot rigs, so staggered seasonality planning keeps crews in tight contact with the top end of Lake Amador’s fishery and supports the trophy bass education the venue is known for.
Lake Amador’s structural palette changes through the basin, so crisp sonar mapping of points, reef edges, and descending humps is essential for matching cover to the current tide and wind. Topography surveys show that largemouth bass stage on the seams between a bluff face and the adjacent fall line, which allows California bass fishing teams to present unweighted plastics and punch rigs inside the heavy brush piles while also tracking subtle current breaks.
Selecting cover requires differentiating between primary ambush spots and secondary transition lanes; a shallow brush pile with adjacent deeper water is far more productive than isolated vegetation, especially when bass are backing out to ambush migrating shad. Swim-jig presentations along these choke points, combined with occasional jig flips under lily pads and submerged trees, keep the day’s offerings versatile for changing Lake Amador visibility and ready to intercept trophy bass that rotate through the cover.
Night fishing on Lake Amador demands timing boat paths with the current moon phase, because light levels govern how far from cover largemouth bass will venture to chase surface offerings, and those light windows also dictate whether the boat idles within coves or maintains a slow drift along the main bend. Under a waning crescent the bass are tight to structure, so pause-and-jerk walking baits or slow-rolling swimbaits within two rod lengths of riprap elicit subtle reaction strikes while anglers maintain spool tension.
Around the full moon, the fish push higher in the channel shelves and readily commit to buzzing topwaters yet stay wary of shadows, so keep baits low and maintain tight line to detect the earliest thump, and the hour after midnight often produces a second push. California bass fishing specialists tie in heavier fluorocarbon leaders and adjust drag to quick-set the aggressive trophy bass that spool when the moon amplifies their cruising range, which also helps them dial in consistent night patterns.
Temperature gradients dominate Lake Amador’s fish populations, so vigilant monitoring of surface readings and thermal clines determines whether fasting largemouth bass pull into the warmer flats or retreat to the cooler main-lake drop-offs, and the best crews overlay that data with wind direction to predict current-rider behavior. When the water warms past the mid-60s, bass aggression spikes near the thermocline, so cast deep-running crankbaits along the transition before they invert toward the deep coolers and the migrating bait schools pull through the same corridor.
Conversely, in the cold fingers of early spring, the bass suspend in the 15- to 20-foot range hugging brush piles where the sun can heat the columns fastest, necessitating down-shot rigs and finesse worms to keep the lure in the narrow bite window. Adjusting retrieve speed and line size for these temperature bands keeps the trophy bass reacting positively even when Lake Amador’s thermal structure shifts daily and concentrations migrate from the main lake to the tributary mouths and timbered coves.
Tournament runs on Lake Amador for the California bass fishing circuits hinge on methodically scouting the spawn transition in March and April, pairing electronics data with on-water observation to score early bites on nearby coves, and logging the last high-water push that reorganizes the bait. Weighing four to five fish requires balancing aggression with conservation, so teams alternate between a shallow chatterbait and a weedless finesse worm to cover areas where the largemouth bass are staging while keeping cull decisions fluid.
In the late-summer series, success depends on punching mats and offshore brush with dropshot setups that mimic stunned baitfish, while deployment of backup deep-diving crankbaits keeps the trophy bass tensions high and ready for the afternoon surge. Competitive anglers also rotate anglers between front and back of the boat to keep fatigue low and leverage real-time wind-swell shifts that dictate Lake Amador bite windows, ensuring the team stays sharp for both practice and final flights.
Catch and release is the standard operating procedure for the bulk of Lake Amador’s largemouth bass, and handling protocols begin with wet hands and a landing net that minimizes abrasion to the fish while reducing air time to the bare minimum. Use needle-nose pliers to back out hooks quickly while the bass is still in shallow water to shorten the fight time and prevent air exposure, and keep the fish’s head slightly elevated to maintain a clear airway.
For trophy bass destined for release, revive them alongside the boat, holding them upright in a slow current until gill movement is strong before easing them back; this is especially critical when anglers push release limits during high-pressure events and need to ensure every specimen swims away strongly. Documenting releases with a quick photo at water level keeps the focus on population sustainability and reinforces Lake Amador’s reputation as a premier California bass fishing destination, while also allowing crews to log trends for future trips.
