4,160-acre reservoir near Bend. 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 outline encloses 4,227 acres, worked by 22.2 miles of shoreline — one island included. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Figure 5.3 mi of water from one end to the other, 3.3 mi at the beam. It sits in Deschutes County. Its nearest charted neighbour, South Twin Lake, is 5 mi to the south.
Spring rainbow trout on Crane Prairie Reservoir hold shallow, usually 4 to 15 ft. Depth-wise the year is flat: 4 to 15 ft in summer, 3 to 15 ft once it turns cold. The chart's best answer is Cultus River inflow — inflow / creek mouth, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
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 | 4 to 15 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Cultus River inflow (3 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 15 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Cultus River inflow (3 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 15 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Gravel shoal (3 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 15 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (6 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is 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 (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (6 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. Start at Old creek channel. It's a creek channel holding about 10 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
