New Melones Lake, CA

About New Melones Lake

New Melones Lake is a large reservoir on the Stanislaus River in the Sierra Nevada foothills of central California, straddling the line between Calaveras and Tuolumne counties. When full it is one of the biggest lakes in the state, with deep, clear water, long winding arms, and dramatic canyon walls of oak and chaparral. Because it is a deep, cold-water impoundment, the lake stratifies in summer and holds a strong year-round trout and kokanee fishery alongside warm-water bass — a combination that makes it a true multi-species destination.

Anglers know New Melones best for its rainbow trout, which routinely run from solid keeper size to genuine trophies, and for its kokanee salmon during the warmer months. It also has an excellent bass fishery — largemouth, spotted, and smallmouth — plus crappie, bluegill, and channel catfish. The lake's size, depth, and water-level swings (it can fluctuate dramatically between wet and dry years) mean structure changes from season to season, rewarding anglers who scout, watch their electronics, and adapt.

Fish Species

New Melones supports a genuinely diverse fishery, which is a big part of its appeal:

• Rainbow trout — the signature species. Stocked and holdover rainbows grow fast on the lake's abundant shad forage, and large, deep-bodied fish are common. This is what most cold-water anglers come for.
• Kokanee salmon — a landlocked sockeye that has become a popular summer target for trollers. They school in the thermocline and offer fast action and excellent table fare.
• Largemouth, spotted, and smallmouth bass — all three black bass are present. Spotted bass in particular have thrived and provide steady year-round action around rock and points.
• Crappie and bluegill — panfish hold around brush, submerged timber, and coves, especially in spring.
• Channel catfish — found in the warmer arms and flats, best in the warmer months.

The standouts are clearly the trout and kokanee for cold-water anglers and the bass for warm-water anglers — few California foothill reservoirs cover both as well as New Melones.

Best Seasons & Times

Spring is arguably the best all-around season. As surface temperatures climb, trout move shallow and feed aggressively, and the bass push up to spawn in the backs of coves and along rocky points. Crappie and bluegill also stack up in the brush. Early morning and the last hour of light are prime.

Summer brings strong thermal stratification. Trout and kokanee go deep, holding in the cooler, oxygenated layer, so trolling with downriggers or leadcore becomes the productive game. Bass shift to deeper structure and feed best early and late, with topwater action possible at dawn and dusk. Catfishing in the warmer arms picks up after dark.

Fall cooling pulls trout and bass back toward the surface and into a more active feeding mode as they fatten up before winter. This is another excellent window, particularly for bass chasing bait on points and trout returning to trollable depths.

Winter can be slower but rewards patience — trout fishing near the dam and main-lake areas can be very good for quality fish, and bass will still bite slowly worked baits on warmer afternoons. Overall, dawn and dusk are the most consistent times year-round, with overcast, stable-weather days often outproducing bright bluebird conditions.

Techniques & Baits

For trout:

• Trolling is the bread-and-butter method — pull threaded nightcrawlers behind dodgers/flashers, small spoons, Rapala-style minnow plugs, or grubs. Match trolling depth to the season (near surface in spring/fall, deep with downriggers or leadcore in summer).
• Bank and bait anglers do well with floating dough bait, inflated nightcrawlers, or a crawler/marshmallow combo fished off the bottom, especially near the dam and main-lake points.

For kokanee:

• Troll slowly with dodgers ahead of small hoochies, spinners, or kokanee-specific lures tipped with scented corn. Use a downrigger to stay in the thermocline and fish multiple depths until you locate the school.

For bass:

• Work soft plastics — drop-shot rigs, Senko-style stick baits, and finesse worms — around rock, points, and submerged timber, which is especially effective for spotted bass.
• Crankbaits, jerkbaits, and swimbaits that imitate shad shine when fish are chasing bait, and topwater plugs produce at first and last light in warmer months.

For panfish and catfish: small jigs and live minnows around brush take crappie; nightcrawlers and prepared/cut baits on the bottom in the warm arms take channel cats, often best after dark.

Access & Launches

New Melones Lake is a federal reservoir managed for public recreation, and it offers good public access for both trailered boats and shore anglers. There are developed launch areas with paved ramps in the main recreation zones, along with a marina that provides services such as boat slips, rentals, and fuel. Because the lake level can fluctuate substantially between wet and dry years, the usable ramp lanes and shoreline can change a great deal — it is always smart to check current lake-level and ramp conditions before towing a boat, as low-water years can limit launching.

Shore and bank fishing are available in the developed recreation areas and along accessible points and coves, and there is camping near the lake for multi-day trips. Day-use and camping areas typically involve standard recreation fees. For the most reliable and current information on which ramps are open, lake levels, and facility hours, check with the managing recreation agency before your trip.

Regulations & Licenses

A valid California sport fishing license is required for all anglers of the applicable age, and it must be displayed as required while fishing. New Melones is managed under California's freshwater regulations, and specific bag, size, and gear limits apply and can vary by species and over time — for example, trout, bass, and other species may carry their own daily limits or size restrictions, and some rules change seasonally.

Because regulations are periodically updated, always confirm the current rules before you fish. Check the California Department of Fish and Wildlife freshwater regulations for New Melones and the Central region, including any species-specific limits, special gear restrictions, and seasonal changes. If you plan to keep fish, know the current daily bag and possession limits, and practice careful catch-and-release on any fish you do not intend to harvest.

Frequently Asked Questions

What is New Melones Lake best known for catching?
It is best known for rainbow trout — including large, well-conditioned fish that feed on the lake's abundant shad — and for kokanee salmon in the warmer months. It also has a strong black bass fishery (largemouth, spotted, and smallmouth) plus crappie, bluegill, and catfish, making it a true multi-species lake.

When is the best time of year to fish New Melones?
Spring and fall are the standout seasons. Spring brings trout shallow and bass up to spawn, with great panfish action in the brush. Fall cooling reactivates both trout and bass near the surface. Summer is productive for deep trolling of trout and kokanee, while winter offers slower but quality trout fishing. Dawn and dusk are the most consistent times year-round.

How do you catch trout and kokanee at New Melones?
Trolling is the most productive method for both. For trout, pull crawlers behind dodgers, small spoons, or minnow plugs near the surface in spring and fall, and go deep with downriggers or leadcore in summer. For kokanee, troll slowly with dodgers ahead of small hoochies or spinners tipped with scented corn, using a downrigger to reach the thermocline. Bank anglers also catch trout on dough bait and inflated nightcrawlers.

Do I need a license to fish New Melones Lake?
Yes. A valid California sport fishing license is required for all anglers of the applicable age. The lake is managed under California freshwater regulations, and bag, size, and gear limits apply and vary by species and season. Always check the current California Department of Fish and Wildlife rules before your trip, since regulations and lake conditions can change.
