On the chart, Loch Coulside or Loch Cuil na Sithe draws 54 acres inside 2.1 miles of shoreline. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout.
Come spring, look for brown trout tight to the bank in 2 to 14 ft. The depth story barely changes: 4 to 14 ft through summer, 2 to 14 ft in winter. If you only fish one area, make it Break off the point: a drop-off around 6 ft that scores prime in summer. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
