Loch Doon

Loch Doon, situated at the source of the River Doon, is Ayrshire's largest water body, stretching 6 miles long and up to 1½ miles wide. The loch has been dammed for hydroelectric power, causing water levels to fluctuate by as much as 40 feet. Due to significant afforestation in the vicinity, the water has become relatively acidic.
The loch is home to brown trout (averaging 8 ounces, with some over 15 pounds), Arctic charr, perch, and sizable pike. Although salmon could theoretically enter the loch, they are seldom observed or caught. Anglers should be particularly cautious when fishing from the shore due to the unstable bank conditions caused by fluctuating water levels. The southern end is usually the most fruitful for fishing, but fish can be caught from nearly any shoreline spot. All legal fishing techniques are permitted.
