Loch Lomond is still producing, according to a kayak fisherman who fished the lake on Saturday. He trolled nightcrawlers in one of the deeper areas of the lake for a limit of trout in just a couple hours. With surface temperatures rising at Loch Lomond, it is time to fish deep for the trout. Largemouth bass are always an option for this lake. Go early and fish the shadowy areas along the banks.
