Don Pedro Reservoir, CA

About Don Pedro Reservoir

Don Pedro Reservoir is a large, deep impoundment on the Tuolumne River in the Sierra Nevada foothills of California, straddling the line between Tuolumne and Mariposa counties east of Modesto. When full it sprawls across roughly 13,000 surface acres with around 160 miles of shoreline, reaching into long, twisting arms and coves framed by oak-studded hills. Its sheer size, depth, and clean cold water make it one of the most versatile fisheries in the central Sierra foothills, offering everything from open-water trolling to tight, rocky bass structure.

Anglers know Don Pedro best as a two-headed fishery: a premier coldwater destination for kokanee salmon and stocked rainbow trout in the deeper main body, and a strong warmwater lake for black bass — largemouth, smallmouth, and spotted bass — along its endless points, coves, and submerged timber. The combination of quality trout, kokanee, and bass in one big lake is what keeps boaters coming back year-round.

Fish Species

Don Pedro supports a broad mix of cold- and warmwater gamefish. The standouts are the kokanee and trout in the open water and the diverse bass fishery along the structure.

• Kokanee salmon — A landlocked sockeye and the lake's marquee coldwater target. Don Pedro is regarded as one of the better kokanee lakes in the region, with fish that can run respectably large by California standards.
• Rainbow trout — Present from plants and holdovers, providing reliable trolling and bait action, especially in the cooler months and at depth in summer.
• Largemouth bass — Found throughout the coves, flats, and shoreline cover.
• Smallmouth bass — Thrive on the lake's rocky points, bluffs, and gravel — a real strength of this deep, clear water.
• Spotted bass — Increasingly common and aggressive, often schooling on points and offshore structure.
• Panfish and others — Bluegill, crappie, and catfish round out the lake, offering fun light-tackle and bank options.

Best Seasons & Times

Spring is prime time. As water warms into the 50s and 60s, bass move shallow to stage and spawn around coves and points — often the best window of the year for numbers and big largemouth. Trout and early kokanee also fish well near the surface and upper water column before the lake stratifies.

Summer pushes the coldwater fish deep. Kokanee and trout drop down to find cool, oxygenated water, so downriggers and counting your line down become essential. Bass shift to a low-light pattern — fish points, bluffs, and deeper structure early and late, and look for spotted and smallmouth bass schooling offshore. Midday heat means going deep or going home.

Fall brings cooling water and renewed shallow activity. Bass feed up before winter, and the lake's beauty and lighter crowds make it a favorite season. Kokanee approach the end of their cycle.

Winter is slower but productive for trout, which roam shallower in the cold water and respond well to trolling and bait. Bass fishing turns finesse and deep, with slow presentations the rule. Across all seasons, the classic early morning and late evening low-light windows are the most consistent for both bass and trout.

Techniques & Baits

Match your approach to the target and the season:

• Kokanee — Troll slowly (around 1 to 1.5 mph) with a dodger or small flasher ahead of a hoochie, micro-spoon, or kokanee bug, tipped with brined corn (white shoepeg corn dyed and scented is a staple). Run downriggers and pay close attention to depth — find the fish on electronics and put baits right in the zone.
• Rainbow trout — Troll spoons, small minnow plugs, or a worm behind a dodger; in summer get down with leadcore or downriggers. From the bank or anchored, dough bait or nightcrawlers off the bottom and inflated crawlers work well, especially near the dam and main-lake points in cooler months.
• Smallmouth and spotted bass — Lean on finesse on this clear water: drop-shot, Ned rig, shaky head, and small swimbaits worked on rocky points, bluff walls, and gravel. Jigs and tubes shine around rock. When fish school offshore, a small swimbait or jerkbait can draw fast strikes.
• Largemouth bass — Work coves and cover with soft plastics (senkos, creature baits, worms), jigs, spinnerbaits, and crankbaits along points and transitions. In spring target shallow staging and bedding fish; in summer fish deeper structure during low light.

Good electronics make a big difference here — the lake is deep and structure-rich, and finding the right depth band is often the whole game.

Access & Launches

Don Pedro is a large, well-developed recreation lake with public boat-launch facilities, marina services, and developed recreation areas operated around the reservoir, along with camping and day-use options. Because it is primarily a deep, sprawling impoundment, it is very much a boater's lake — a boat (or a guided trip) opens up the kokanee, trout, and offshore bass fishing that the reservoir is known for, though bank anglers can find shoreline access at developed areas and near the dam for trout and panfish. Launch availability and recreation-area access can shift with the season and with water levels, which fluctuate on this storage reservoir, so it's smart to confirm conditions before you tow a boat out. Standard boating practices apply: have safety gear aboard and be mindful of other recreational traffic, which is heavy in summer.

Regulations & Licenses

A valid California fishing license is required for anyone 16 and older, and it must be carried while fishing. Don Pedro is managed under California's freshwater sportfishing regulations, and size, slot, and bag limits — as well as any gear or seasonal rules — vary by species and can change from year to year. Before your trip, check the current California Department of Fish and Wildlife regulations for the limits that apply to trout, kokanee, and black bass, and watch for any special or local rules posted at the lake. Practicing selective harvest and careful catch-and-release, especially on bass during the spring spawn, helps keep this fishery strong.

Frequently Asked Questions

What fish is Don Pedro Reservoir best known for?
Don Pedro is best known as a strong kokanee salmon and rainbow trout lake in its deep, cold main body, plus an excellent black bass fishery — largemouth, smallmouth, and spotted bass — along its many rocky points and coves. The mix of quality coldwater and warmwater species in one big reservoir is its calling card.

When is the best time to fish Don Pedro Reservoir?
Spring is the best overall window: warming water pulls bass shallow to spawn and keeps trout and early kokanee near the surface. Fall is also excellent as bass feed up in cooling water. In summer the coldwater fish go deep, so you'll need downriggers for kokanee and trout, and you should fish bass early and late during the low-light hours.

Do I need a boat to fish Don Pedro?
A boat helps a lot. Don Pedro is a deep, sprawling reservoir, and the kokanee, trout trolling, and offshore bass fishing it's famous for really require a boat or a guided trip. Bank anglers can still find shoreline access at developed recreation areas and near the dam, mainly for trout and panfish.

How do you catch kokanee at Don Pedro?
Troll slowly, around 1 to 1.5 mph, using a dodger or flasher ahead of a small hoochie, spoon, or kokanee bug tipped with brined corn. Use downriggers and your electronics to find the exact depth the fish are holding — kokanee suspend and move with water temperature, so dialing in the depth is the key to consistent catches, especially in summer.
