I truely doubt that the fish at the outflow at Pymie are from Shenango.  It would take some high water for the fish to navigate some stretches of the river and than the fish would have to fight a very strong head current.  Is it possible ,yes, but not likely. The only time a fish could go through the shallow riffles would be when the water is extremly high.  Years ago when they PFC put some metal tags in the lips of some eyes (Pymie) I caught one below the dam.

Thanks , pics are from upper Shenango (Pymy flow) last year. I've fished that river many a day and I never seen or heard of a water way dam on that portion of river. I've never walked all the down to the Jamestown bridge from upstream but very close. There may be some kind of obstruction due to all the trees piled up in that area but I'll be surprised if there is some type of perminent structure there. Not saying it isn't there just never heard anyone ever mention it over many years of fishing that area. Seems like a area below a structure like that would be a hot holding area for Walleye and the word would have spread. No doubt in my mind that fish can migrate all the way up from Shenango Lake to the Pymy out flow. Many years ago Shenango Lake was stocked with Hybrid Stripers (still is) none in Pymy. A guy fishing the Pymy out flow area landed a huge Striper while plugging for Musky that was around 20lbs. The picture hung in the Hot Spot bait shop for years. I beleive another huge Striper (maybe bigger ) was caught not long after also in the upper river flow. Those fish came from Shenango Lake stockings. I beleive the one Striper was recorded by the Fish Commission as a record in the hybrid species back then. For some reason they don't reconize the hybids in there own category, they lump them in with Inland Stripers , but the guy's name and fish were recorded at the time. Interested in seeing some photos of that dam or structure when you get them.

A spawning walleye can travel over 20 miles to find that spawning site.

I remember reading somewhere(or talking to someone, can't reamember) that although Pymy isn't/wasn't stocked with hybrids they did raise some at the hatchery ponds there at some point and some escaped.  I heard of a few being caught in the lake also.
 
Other than right below Pymatuning and Shenango Lakes, has anyone ever had decent luck with eyes in the river say in the greenville area or maybe down in New Castle far from the lakes?  Just wondering if there are lots of eyes throughout the entire river and not just concentrated below the two lakes. 

I agree that the eyes probably do migrate up from shenango lake on a spawning run and some just stay in the river after the spawn. That is along way to make it all the way to the dam below pymy. Anyone have an idea of how far? Checked the flow charts and its up a good bit the last few days, might be a good time this weekend but with that snow coming...

I would say Shenango Lake by river to Pymy maybe 12-15 miles. Yes there have been some Stripers caught the last few years out of Pymy. They claim they were not introduced but they are showing up on occasion throughout the lake. Really not a bad thing in my view. Yes the river holds Walleye , Musky, Pike, and so on throughout the Greenville area as well as south to Pulaski in the lower stretch. The biggest problem is access, private land, plus shore line banks are very muddy and loaded with roots and tree debris. Most areas are just impossible to wade fish. The lower Shenango does have several drops in water levels with man made waterfalls if you decide to canoe . 

The farthest I've went down stream was down around the first bend where there's a few camps on the opposite bank. Your right there's not many spots to fish because of all the high banks and dead falls. I'd like to put some time into the river...finding the right hole and you'd probable hit the jackpot with some eyes and muskie.

34 years ago, John "Jake" Satonica, caught a pure bread striper below the low head dam at Pymatuning weighing in the 30# range.
That fish traveled up from Shenango Lake. By the way...Jake invented the grandma lure.

I found some sort of man-made structure on the upper river but it is just south of Greenville.  Not exactly sure what it is, but it isn't a normal low head dam....

I'm aware of the Stripers that are [or were ] mounted at Richters'. Dave said they "came up from the Shenango". With all that I've read from you guys, I'm beginning to doubt myself on what I saw. And no, I don't eat mushrooms, peyote or anything else that would induce visual hallucinations,lol! Late this year in the fall I was talking to s agroup of kayakers and one of them said he knew where I was talking about, the that doesn't prove anything  and I'm not implying that it does. With all of this fair weather we've been having, I guess I'll have to drive there and shoot pictures as best as I can get them. As posted earlier, that doesn't prove what I shot is where I'm saying it is, but also, I wouldn't BS anybody. If it's there, it's there. Spoonchucker cracked me up with his comment "Nay" after I wrote about naysayers and troutguy alos with "pics or it didn't happen" which I also commented on. Overall, you guys have been helpful in offering possible explanations and it's appreciated. It's also appreciated that the comments weren't condescending, argumentative, attacking etc... . I was expecting at least a few of those.
