112-acre lake near Mason County. 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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Island Lake runs 112 acres with 1.6 miles of edge. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 41% of the surface — that's where the groceries are. Figure 0.5 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Mason County. Closest neighbour on DepthScout: Lake Limerick, 4 mi northeast of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 6 to 30 ft. Break off the point is the standout, a drop-off at roughly 12 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. 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 | Break off the point (12 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (12 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (12 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (12 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 12 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Break off the point, a drop-off in about 12 ft of water that rates prime for smallmouth bass in winter. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
