What You'll Find at West Branch Reservoir

West Branch Reservoir is a 500-acre impoundment in Putnam County that holds largemouth bass, channel catfish, and sunfish. The lake sits in rolling terrain with wooded shorelines and shallow coves that warm quickly in spring—exactly the kind of structure largemouth prefer. Access is straightforward: a public boat launch on the north end, parking for bank anglers, and enough elbow room that you won't feel crowded even on weekends.

The reservoir runs roughly north to south, with the dam at the southern end and the upper arms branching into narrower creek channels. Those upper arms are where the real fishing happens. Water clarity varies by season—clearer in winter, stained in summer after heavy rain—but the lake rarely gets so murky that you can't fish it productively.

Key Takeaways

  • Largemouth bass respond best to shallow cover in spring and early summer, especially around fallen timber and weed edges in the upper creek arms.
  • Channel catfish bite reliably year-round on chicken liver, cut shad, or prepared stink baits fished on the bottom near the dam and in deeper holes.
  • The public boat launch is on the north shore; bank access is available but limited to a few parking areas, so arrive early on weekends.
  • Summer water temperatures can exceed 80 degrees, pushing bass deeper during midday; fish early morning and evening or target deeper structure.

Spring Bass Fishing in the Upper Arms

From March through May, largemouth move shallow to spawn and feed aggressively before the heat sets in. The upper creek arms—the narrower branches that feed the main lake—are where you want to be. Water warms faster in these shallower, darker-bottomed sections, and bass stage there before moving into the shallowest bays.

Fish the outside bends of the creek channel where current scours deeper holes, and work any fallen timber or root wads you find. Spinnerbaits in white or chartreuse, crankbaits that reach 4 to 8 feet, and soft plastics rigged on light jig heads all produce. Early morning is non-negotiable in spring—the first two hours after sunrise will outfish the rest of the day by a factor of three.

Water levels can fluctuate in spring depending on dam operations, so check conditions before you go. A rising lake pushes bass into newly flooded brush and timber; a falling lake concentrates them in the deepest remaining pockets. Either way, the transition zones—where shallow water meets deeper structure—hold the most fish.

Summer Catfish and Deep Bass

By June, surface temperatures climb into the low 80s, and largemouth retreat to deeper water and shade. This is when catfish fishing becomes the better bet. Channel cats bite all day and all night, and they don't care about water temperature the way bass do. Fish the dam face in 15 to 25 feet of water, or target the deeper holes in the main lake basin.

Chicken liver is the standard bait—cheap, effective, and easy to cast. Cut shad works just as well, and prepared stink baits like dip baits or dough balls will draw cats from a distance. Use a three-way rig with a sinker on the bottom and your bait on a 12-inch dropper, or simply fish a slip sinker rig on a basic catfish rod. You don't need anything fancy; a medium-heavy spinning rod and 15-pound mono will handle anything the lake holds.

If you want to fish for bass in summer, focus on the deepest structure you can find—the dam face, channel ledges, and the deepest holes in the upper arms. Fish early and late, and be prepared to go deep. A 10-foot crankbait or a soft plastic on a heavier jig will reach the bass that have abandoned the shallows.

Fall and Winter Patterns

September and October bring the best overall fishing of the year. Water cools, bass move back to intermediate depths, and they feed with purpose as they prepare for winter. The upper arms remain productive, but now the deeper edges of the main lake basin hold just as many fish. Fish crankbaits, jigs, and swimbaits along the 8- to 15-foot contour lines where structure meets open water.

Winter fishing is slow but not impossible. Bass suspend in the deepest parts of the lake, and catfish remain active on the bottom. If you're fishing for bass, vertical jigging with a small spoon or blade bait in 20+ feet of water can work. Catfish anglers will find consistent action on the dam face and in the deepest holes, even on the coldest days. Winter is also when the lake is least crowded, so if you prefer solitude, this is your season.

Access and Facilities

The public boat launch is located on the north shore of the reservoir and has adequate parking for trailers. The ramp is concrete and well-maintained, though it can get congested on Saturday and Sunday mornings. Arrive early if you're launching on a weekend, or plan to fish on a weekday when the lot is quieter.

Bank access is more limited. There is a small parking area near the north shore where you can fish from the bank, and another spot on the eastern side, but neither offers much room. If you don't have a boat, call ahead to confirm parking availability. The dam itself is off-limits to anglers, so don't plan to fish from there.

There are no on-site facilities—no restrooms, no concessions, no bait shop. Bring water, snacks, and any tackle or bait you'll need. The nearest town with supplies is a short drive away, so plan accordingly.

Seasonal Timing and Water Conditions

West Branch Reservoir is fishable year-round, but your success depends on matching the season. Spring (March–May) is peak time for largemouth; summer (June–August) favors catfish and early-morning or late-evening bass; fall (September–October) is excellent for both species; winter (November–February) is slow but consistent for catfish.

Water levels are managed by the dam operator and can change week to week. A rising lake is generally better for bass fishing because it floods new cover; a falling lake concentrates fish but can make them harder to locate. Check local fishing reports or call the dam office before you go if you want to know the current water level and recent trends.

Clarity varies. After heavy rain, the lake can turn stained for a few days. In that window, bass bite better because they rely more on vibration and less on sight. Once the water clears again, they become more selective. Winter water is usually the clearest of the year.

Tackle and Bait Recommendations

For largemouth bass, bring a medium-power spinning rod with 10- to 15-pound braided line and a fluorocarbon leader. Pack spinnerbaits (1/2 to 3/4 ounce), crankbaits (shallow and medium-diving), and a selection of soft plastics—4-inch worms, creature baits, and swimbaits. In spring, focus on reaction baits; in summer and fall, mix in slower presentations like jigs and Texas-rigged worms.

For catfish, a medium-heavy spinning or baitcasting rod with 15- to 20-pound mono is all you need. Bring chicken liver, cut shad, and a prepared stink bait. Pack a three-way rig setup and some basic sinkers. You'll also want a net or a stringer if you plan to keep fish.

Sunfish (bluegill and pumpkinseed) are abundant and bite on small jigs, inline spinners, and live crickets or worms. They're perfect if you want to bring kids or if the bass and catfish aren't cooperating. A light spinning rod and 6-pound line is all you need.

Frequently Asked Questions

Do I need a boat to fish West Branch Reservoir?

No, but bank access is limited. There are a couple of parking areas where you can fish from shore, but they fill up quickly on weekends. A boat gives you access to the upper creek arms where the best bass fishing happens, but if you're targeting catfish, you can do well from the bank near the dam or in deeper holes accessible from shore.

What's the best time of day to fish here?

Early morning—first light through mid-morning—is consistently best, especially for largemouth bass. Catfish bite all day and night, but they're most active at dawn and dusk. In summer, evening fishing (two hours before sunset through dark) is often better than midday because water temperatures are lower and bass are more active.

Are there size or catch limits?

Putnam County follows New York State freshwater fishing regulations. Largemouth bass have a 12-inch minimum size and a daily limit of five fish. Channel catfish have no minimum size and no daily limit. Sunfish have no minimum size and a daily limit of 25 fish. Check the current New York State DEC regulations before you fish to confirm these rules haven't changed.

Can I fish at night?

Yes. Catfish anglers often fish at night, and it's productive. Bass fishing at night is possible but requires experience and the right tackle. Make sure you have proper lighting and follow all state regulations regarding night fishing. The reservoir is open to fishing 24 hours a day, but always check local rules before you go.

What should I do if the water level is very low?

Low water concentrates fish in the deepest holes and makes the boat launch harder to use. If the ramp is unusable, you'll have to fish from the bank. Call ahead to confirm launch conditions. Low water is actually good for catfish fishing because they stack up in the remaining deep pockets, but it's harder on largemouth because they have less shallow cover to hide in.
