71-acre lake near Albany. NH GRANIT / NH Fish & Game survey water. The lake tops out around 30 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. The season-by-season read for each species follows, from the map's own numbers.
Iona Lake maps at 71 acres behind 1.4 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. 40% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.6 mi end to end and 0.3 mi across at its widest. Carroll County claims this one. If the bite dies, Whitton Pond is 1 mi to the south.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Summer pushes them deeper, 9 to 30 ft, and winter fish settle into 4 to 30 ft. The spot to know is Break off the point, a drop-off in about 9 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Break off the point (9 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (7 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Break off the point (9 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 9 to 30 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring smallmouth bass on Iona 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 9 to 30 ft. The chart's best answer is Secondary point — point, 11 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (7 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (11 ft) | Jerkbait, Blade bait |
| Winter | 9 to 30 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring brown bullhead on Iona Lake hold shallow, usually 2 to 8 ft. They move out to 3 to 12 ft in summer and finish the year down in 10 to 25 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |

| Winter | 10 to 25 ft | midday | Deep basin (30 ft) |
In spring, chain pickerel run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 5 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring chain pickerel. Time it for early morning and the evening. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Inline spinner (silver), Small spoon (red/white) |
