How many places have you heard of or seen the Isonychia mayflies?
We know they are big time on the Pit River most years. Mid-September is killer.
I heard they are on the Middle Fork of the Feather River down in the canyon in the Fall.
I have seen them on Battle Creek near the Coleman Fish Hatchery east of Red Bluff.
I saw some on the Trinity River once in the Fall near Junction City.
I guess they should be somewhere on the Klamath River?
