24-acre pond near Putnam, Thompson. The lake tops out around 10 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 rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 24 acres wrapped in 0.9 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.3 mi, about 0.2 mi across. Providence County claims this one. If the bite dies, Bowdish Reservoir is 2 mi to the southeast.
Spring rainbow trout on Keach Pond hold shallow, usually 3 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 10 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 10 ft | dawn | Deep basin (10 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 1 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 1 to 10 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 10 ft | dawn & dusk | open water | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 3 to 10 ft | night & dawn | Deep basin (10 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 10 ft | dusk & dawn | open water | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 10 ft | dawn | Deep basin (10 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores good in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 3 to 10 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 10 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 10 ft | dawn | Deep basin (10 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
