Once or twice a year a friend or customer tells me they encountered a big hatch of Callibaetis mayflies on Pass Lake. I’ve fished Pass Lake a quite frequently for about 15 years now and I’ve often seen Callibaetis, but I’ve never seen numbers of them big enough to stir much interest from me or the fish. I always told them they were almost certainly seeing the big chironomids bombers and that Pass Lake doesn’t get anything beyond a sporadic Callibaetis hatch.
Yesterday, I proved myself wrong.</p
