Little Lava Lake was also a no dry fly day for Sean and I this week. That was a total surprise and while it was also a disappointment, we didn’t lack any fish to the net using nymphs. 
For the most part we caught the majority of the total for the day on Callibaetis Cates. Some on a Spicy Squirrel and some on a Poxy Back Callibaetis. Later in the day it was apparent the more shallow water nymphing had ended and I had a hunch we’d get more bites going to the deeper areas and anchored in 16 feet (about as deep as we can find on Little Lava) and built a deep water nymph rig with a slip indicator and used a Red Worm on the bottom set at 15′ and a Cate 2 feet above that. Most of the fish we landed on this set up came on the Blood Worm. 
Hopefully the next time we are there the hatch will be better, or at least the fish will eat some ants and beetles like they usually do.
