129-acre lake near Littleton. NH GRANIT / NH Fish & Game survey water. The lake tops out around 50 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Partridge Lake draws 129 acres inside 1.9 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. 35% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.8 mi, about 0.4 mi across. The water lies in Grafton County. The nearest mapped water is Dodge Pond, 2 mi to the southwest.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 7 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (7 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (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 (19 ft) | Blade bait, Jigging spoon |
Spring yellow perch on Partridge Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 7 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (7 ft) | Small jig + curly tail, Perch-pattern micro crank |

Early season chain pickerel use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 5 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a weedless spoon + trailer or a buzzbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (7 ft) | Inline spinner (silver), Small spoon (red/white) |

| Winter | 5 to 18 ft | dawn | Shallow bay flat (7 ft) | Jigging spoon (through ice) |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 7 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (7 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small sponge spider (fly), Micro tube jig |

| Winter | 10 to 25 ft | midday | Back-bay flat (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 9 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (19 ft) | Blade bait, Hair jig |
Start shallow in spring: white perch sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 40 ft; cold water stacks them in 20 to 50 ft. Top water on the chart: Deep basin, a deep basin in the 49 ft range, prime in winter. Fish it in early morning and you'll meet the bite. Throw a small spinner rig drifted or a 1/8 oz jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (7 ft) | Small jig + curly tail, Inline spinner (silver) |
