Hosmer Lake is all open and fishing is off to a great start. Olive Chironomids, Balanced Minnows and Leeches, Damsel Nymphs, Callibaetis Cate and Red PT Jig. Callibaetis hatches are starting, beetles and ants are important, add some #14 black Elk Hair Caddis to your box because it imitates the spring time Alder Fly hatch we will see over the next few weeks, and make darn sure you have patterns to imitate the Traveling Sedge.
Upper and Lower Lakes are good, on the lower lake try a Tequila Blob on an intermediate line too.
