80-acre lake near Johnson Landing. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Florence Lake draws 80 acres inside 1.8 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 30% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.8 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Pierce County. For a second option, Lake Louise lies 6 mi east.
When the water first warms, brown trout slide up into 3 to 25 ft. Summer is a 9 to 30 ft game here, winter a 4 to 30 ft one. Start at Creek inflow. It's an inflow / creek mouth holding about 28 ft of water and rates prime come fall. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
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 25 ft | dawn & dusk | Creek inflow (28 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (30 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Creek inflow (28 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft chart-limited; documented 5 to 35 ft | dawn | Creek inflow (28 ft) | Jigging spoon, Small stickbait (slow) |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 6 to 30 ft for winter. Summer rainbow trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 28 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
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 | 5 to 20 ft | dawn & dusk | Shallow bay flat (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (28 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Old creek channel (22 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (30 ft) | Jigging spoon, Tube jig (white) |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. As the season builds they drop to 4 to 15 ft, wintering in 10 to 25 ft. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 5 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (5 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (5 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Back-bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (30 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 9 to 30 ft. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

Florence Lake is about 30 ft (9 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target brown trout, rainbow trout, bluegill, largemouth bass on Florence Lake.
Creek inflow is the top-rated area: an inflow / creek mouth in about 28 ft of water that rates prime for brown trout in fall. Every other rated spot, per species and season, is on the map above.
For brown trout, the summer bite is best in after dark and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
