30-acre lake near Argyll and Bute. The lake tops out around 57 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 30 acres wrapped in 1.3 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. 47% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 17 to 57 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 48-ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (14 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
