8-acre lake near Highland. The lake tops out around 40 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Species by species, here's what the data says the year looks like.
The drawn water covers 8 acres wrapped in 0.5 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 36% of the surface on the model — that's where the groceries are. Highland claims this one. Lochan Coire an Lochain sits 3 mi south — the closest neighbouring chart.
In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 12 to 40 ft, and winter fish settle into 5 to 35 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) 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.

Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |

Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.
