1,841-acre lake near Sprague. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 1,880 acres wrapped in 12.8 miles of bank — one island included. A middling shoreline index (2.1) gives it some bays to work without being a maze. Call it 4.9 mi long by 1.1 mi wide at the broadest reach. It sits in Lincoln County. Its nearest charted neighbour, Williams Lake, is 18 mi to the east.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. The chart's best answer is Break off the point — drop-off, 11 ft, prime for winter. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
Spring crappie on Sprague Lake hold shallow, usually 2 to 8 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).

Early season channel catfish use the shallows, holding in 3 to 12 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. The chart's best answer is Deep basin — deep basin, 15 ft, prime for winter. Best bite is after dark and the evening.

| Winter | 5 to 15 ft chart-limited; documented 20 to 40 ft | midday | Deep basin (15 ft) |
Spring bluegill on Sprague Lake hold shallow, usually 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.

Come spring, look for common carp tight to the bank in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 5 to 15 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come winter. Prime time lands in early morning and the evening.

Come spring, look for rainbow trout tight to the bank in 4 to 15 ft. Through summer count on 4 to 15 ft; the winter hold is 3 to 15 ft. Start at Break off the point. It's a drop-off holding about 11 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
