Hosmer Lake access is now open. Fish are spread out in both sides of the lake and a lot of them in the channels. Look for fish to be pretty keyed on damsel nymphs, chironomids, leeches, scuds and water boatman now. The hatches are very slow, but you should be able to get fish on the edges on ants, beetles, and chubbies. Approach the fishing with an indicator mindset and a stripping mindset. Some days it is not all of one thing, and the fish want it moving more, or moving less. With the sinking line approach the best 3 at Hosmer are a Camo Intermediate, a Hover and an Emerger Tip which is a 5 foot clear slow sink tip. Think about you want your flies to move. Steady on the bottom. Steady mid-depth. Or ascending to the surface. Imagine a Waterboatman for example swimming from the reeds to the surface. That Emerger Tip is the best line to mimic that.
