553-acre reservoir near Southeast. The lake tops out around 64 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Species by species, here's what the data says the year looks like.
East Branch Reservoir maps at 540 acres behind 12.1 miles of shoreline, with 3 islands in the mix. An index of 3.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 26% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 2.1 mi end to end and 1.4 mi across at its widest. Putnam County claims this one. Bog Brook Reservoir sits 1 mi north — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Creek inflow, an inflow / creek mouth in about 5 ft of water that rates prime for walleye in spring. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Creek inflow (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Secondary point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (62 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for common carp tight to the bank in 2 to 10 ft. They move out to 3 to 15 ft in summer and finish the year down in 10 to 30 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (4 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 18 ft | midday | Shallow bay flat (4 ft) | |
| Winter | 10 to 30 ft | midday | Deep basin (62 ft) |
