[left]we are 30min. west of Harrisburg, salmon would be great but I don't know if they could handle the water, over the past 10 years the oxygen levels of the river have gone down. a lot of the weed beds died off from pollution the small mouth population is cut in half of what it was. We have to get the river back into shape then work on the fish. It would be great to see more fish all around!!! salmon would kick ass though.

From what I can see (Being an engineer with a background in Geology) the susky is being mismanaged to the extreme. The O2 levels are a result of 2 things Plants and aereation. Warmer water carries lower disolved O2. Geologically the susky is an "Oligotropic" river system (Lacking in plant nutrients and having a large amount of dissolved oxygen throughout. Used of a pond or lake.) being rocky with lots of rapids. However the river has been dammed up to produce reservoirs for the Hydro plants. This causes siltation and a warming of the water - therefor lower O2 levels.
Small mouth bass need about the same environment as trout. Cool water with medium to high disolved O2. This is why there is a problem in the susky with the small mouth.
Salmon on the other hand use the river as a thru-way only. They do not live in the river but for a short time. When adult they are in the rivers in the fall to early winter for spawning - then die providing nutrients for the river system (Fertilizer for plants and invertibrates). The eggs spawn in the creeks - and the fry live in the creeks or the river itself from 3 to 12 months. When they smolt then they head out to the open ocean where they grow at an amazing rate.
Small mouth bass on the other hand have to survive through the hot summers with low O2 levels...
This can be corrected by dredging the susky to provide cooler water areas.
Next is proof of mismanagement....the susky was never supposed to have walleye in it. Walleye are a top level preditor feeding heavilly on bass fry. Next are the musky...Need I say more?
PA stocks 1,000,000 walleye fingerlings in the reservoir near holtwood, and 80,000 musky every year.
You cant even catch a blue gill sunfish in the reservoir as the ballance between preditor and prey is all out of whack.
