Fished Lost Lake in my personal pontoon boat. It took a couple of hours but finally located the triploids. Fished sink tip fly line. Used three different flies and all worked well when the fish were found. Olive damsel fly nymph, black wooley bugger, and a black leech. I trolled around the Lake about 90 feet from shore for about two hours until the big fish were located. When located I had a fish on with every cast. Used barbless hooks to practice catch and release. I did keep one fish.
Lots of fun. But it does take a little work to find them. Hard to fish this lake without a boat.
