Fishing Gartmorn Dam: what the data says
144-acre lake near Clackmannanshire. The lake tops out around 21 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Species by species, here's what the data says the year looks like.
The drawn water covers 144 acres wrapped in 3 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. About 85% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Brown Trout fishing at Gartmorn Dam
Start shallow in spring: brown trout sit in 3 to 21 ft that time of year. Summer fish stay in 6 to 21 ft, and winter fish hold in 3 to 21 ft. Top water on the chart: Break off the point, a drop-off in the 9-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.
