Little Lava Lake is a good one to keep on your radar this week and might be the last place to find and fish a callibaetis dry fly in Central Oregon until 2026.
Beetles and Ants are a good choice in the afternoon.
Blobs, Balanced Leeches and a variety of nymphs like a Red PT Jig, CB Cate, and mostly fish them under an indicator, although a stripped leech, blob or mayfly nymph is a good choice too. An Emerger Tip (5 foot Intermediate sink tip) or a Clear Camo full sink intermediate are solid sink line choices, and have a type 3 handy too.
I haven’t been to (big) Lava Lake lately, but I would think it is a good choice now too. In the fall I have had very nice terrestrial action on the far north end near the rocks.
