Ya can add Wilhelm into the mix also Loby and I'm afraid I do hold the PSFBC* responsible for the fish kill.
While the aquatic herbicides are not (suppose to be) toxic to fish themselves, the drastic changes to the water chemistry, does weaken the fish and makes them susceptible to attack by disease/bacteria.
Last I knew, aquatic plants provide oxygen, habitat and, keep water temperature cooler. Without aquatic plants, less dissolved oxygen; no habitat which affects the food chain and survival of new born fry, and fingerling fishes, and; allows the water temperatures to become even warmer which increases the bacteria/disease that attack the stressed fish.
When questioned why the weeds are being annihilated with herbicides, we hear the plants are so thick and matted they are chocking the lakes. When asked why these weeds were never really a problem in the past, we are told these weeds are of a variety that does more harm than good and they are a species capable of reproducing.
In addition, for the aquatic herbicide to work, the plants must be present which means we now have rotting plant material laying at the bottom of the lake no longer producing oxygen but, nasty contaminates not conducive to healthy fish and I hear certain species of algae just love that stuff.
Add to this, fishes weakened by lack of oxygen, water temperature exceeding fish tolerances, no natural habitat, water quality aiding in the growth of bacteria/disease/algae(s) and "estupendo" we have a PSFBC* fishery that won't sustain minimal requirements (set by the PSFBC*) for stocking of certain fish.
*PennStateFishandBoatCommission. Ever wonder why you see 2 to 3 biologist but, seldom see more then one (if that) law enforcement officer on the water?
For the younger generation who today, enjoy our lakes and streams, ya should of seen it 25 years ago.

Brock I don't know much about the fishery at Shenango Lake or on the river but I do know, from the stories I've heard and the pictures you have posted, you have every right to be concerned about the future of the river.
The river is just another waterway/fishery that has become victim to the "Fish Specific Waters" program engineered by the biologist of the PFBC which in my book was brought on, by special interest groups/clubs. That program was a total flop and was abandoned leaving many of our waters totally destroyed of a once great fishery. Wilhelm, Shenango River/Reservoir, walleye fishing at Pymie to name a few, have all shown a change for the worse over the past 10 to 20 years.
Thank you for taking the time to forward your experience and knowledge to our legislators in hopes of saving our lakes and streams from further corruption. I plan to follow your lead and forward my concerns regarding the lame excuses and bogus reports generated by an agency that sets standards they don't intend to reach regarding the stocking of our waterways.
One of the first questions I will ask is why the hell the PFBC, under the direct guidance of John Arway, is doing work of the EPA involving the supposedly highly contaminated Susquehanna River? There's a story you would find interesting, from the reports of hermaphrodite bass to John Arway being railroaded into office.
I began reading bogus reports being generated regarding the Susquehanna in the magazine "PA OUTDOORS" about 10 years ago and got so pizzed, I quit buying the paper. Now what-do-yo-know, we have a SOS program with the project being the "pet" of John Arway.
I gotta go, my therapist is on the phone.
