570-acre lake near Tumwater. The lake tops out around 28 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 566 acres, worked by 6 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 40% of this chart. The basin spans about 2.5 mi end to end and 0.6 mi across at its widest. It sits in Thurston County. Ward Lake sits 5 mi east — the closest neighbouring chart.
Spring largemouth bass on Black Lake hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 8 to 28 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
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 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 28 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 10 to 25 ft game here, winter an 8 to 28 ft one. The chart's best answer is Deep basin — deep basin, 28 ft, prime for winter. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | 1/16 oz jig + tube, Curly-tail grub |

Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (10 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (28 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 8 to 28 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 7 to 28 ft, and by winter most fish are in 6 to 28 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
