19-acre pond near SANDOWN. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, SHOWELL POND draws 19 acres inside 0.7 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 65% of the surface — that's where the groceries are. You'll find it in Rockingham County. For a second option, Phillips Pond lies 1 mi northwest.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| 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 | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Deep basin, a deep basin in the 25 ft range, good in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |

| Winter | 8 to 25 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (25 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 8 to 25 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |

Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 10 to 25 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Deep basin, a deep basin in the 25 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |

In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Back-bay flat (5 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Back-bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (25 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one.

|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
