The Garcia report does not list
Isonychia,
Paraleptophlebia or
Discosmoecus . . . curiously and coincidently all insects that have adapted to fall emergence. All these insects have "anecdotally" been prevalent on the pulse flow stretch and are now largely absent. Your question has historical significance and anyone who claims history is no indicator of the future hasn't learned from history. (My favorite oft-repeated line from the current administration has been, "Let's not dwell on past mistakes but move forward"

. Somehow you get a pass by not using 20-20 hindsight.
I am working on the Yuba FERC process at the moment and we (SYRCL) are using the (historical) flawed process on the NFF to NOT repeat their mistakes and are biomonitor the crap out of our system. AWA did some test pulse discharges on Canyon Creek in September and
Dicosmoecus and
Isonychia went missing, while other nearby creeks had bumper hatches. SYRCL will now have a biomonitoring site on Canyon Creek.
I rarely have much to say about Cal-Trout but after a long interlude did renew my membership after they published their SOS state of the salmonid report (download it from their site). It is an extremely important document and no matter what your feelings about the organization, they deserve big kudos for this project.
