112-acre lake near Northwood. NH GRANIT / NH Fish & Game survey water. The lake tops out around 20 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.
The outline encloses 112 acres, worked by 1.7 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Roughly 88% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. Rockingham County claims this one. MEADOW LAKE sits 1 mi southeast — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 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 |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Put Shallow bay flat first on the milk run — a weed flat near 3 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.

Keep a small spinner rig drifted or a 1/8 oz jigging spoon rigged through the warm months.
