My spouse and I spent a frustrating two days trying to get our kayaks in the water, and possible fly fish Horsethief Lake. But Mother Nature would have none of that and blew up a storm both Sunday and today. We use sit-on-top kayaks, and in the rollers the lake produced in the winds, we'd likely have spent more time in the water than on it. But I did notice near the shoreline by the camping area at least three huge trout taking flies off the surface and generally having a great time cruising the water, often with dorsal fin exposed like a great white shark. Fascinating to watch, even though there was no way I could have beaten that wind with a dry fly. Were they taking chronomids? I couldn't see a bug on the water. Also spotted two osprey fishing the lake in the cove in the western end of the lake. They each got their fish!
