3,809-acre reservoir near Bonanza. The lake tops out around 40 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Gerber Reservoir draws 3,864 acres inside 27 miles of shoreline. With a shoreline index of 3.1, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 17% of the surface — that's where the groceries are. Tip to tip the water measures near 6.2 mi with a 3.3-mi widest point. The water lies in Klamath County. Closest neighbour on DepthScout: Agency Lake, 49 mi northwest of here.
Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 10 to 25 ft, wintering in 15 to 35 ft. Summer crappie concentrate at Old creek channel, a prime-rated creek channel around 23 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| 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 | 10 to 25 ft | dawn & dusk | Old creek channel (23 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (23 ft) | Jig + minnow combo, Small swimbait (1.5-2") |

Spring yellow perch on Gerber Reservoir hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft.

You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
