48-acre lake near Pierce County. The lake tops out around 18 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Rapjohn Lake runs 48 acres with 1 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. 87% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.4 mi, about 0.2 mi across. The water lies in Pierce County. For a second option, Silver Lake lies 2 mi southwest.
Spring brown trout on Rapjohn Lake hold shallow, usually 2 to 18 ft. Depth-wise the year is flat: 5 to 18 ft in summer, 3 to 18 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
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 | 2 to 18 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 18 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (15 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 18 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (1 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 18 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (15 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: rainbow trout sit in 5 to 18 ft that time of year. They don't go far with the seasons — 5 to 18 ft covers summer, 4 to 18 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 15 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Break off the point (15 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 5 to 18 ft, and winter fish settle into 5 to 18 ft. Deep basin is the standout, a deep basin at roughly 18 ft, rated prime for winter crappie. Time it for early morning and the evening. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.

| 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 | 5 to 18 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Break off the point (15 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 18 ft chart-limited; documented 8 to 20 ft | dawn | Break off the point (15 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (18 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Winter largemouth bass concentrate at Break off the point, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |

| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Put Deep basin first on the milk run — a deep basin near 18 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
