The creek mouths and spring holes now offer the best fishing all around the lake. These may tend to get crowded, so get there early or stay late to get a favorite location. Some of the Henry’s Lake classics such as mity mouse, renegade and smaller crystal buggers are the way to go at these locations.
Action through damselfly activity remains spotty. West side is best. Now the best action is at creek mouths, particularly Targhee Creek. A lot of fish have migrated there to enjoy the cooler water flowing in, but the number of anglers is also numerous to enjoy the active fish.
Responses to damselflies still seems spotty with some action along the southwest corner of the lake. Try leech patterns on an intermediate line with a slow retrieve and with a blood worm trailer at other places. As the lake warms up be ready to fish creek mouths with traditional Henry’s Lake patterns.
