East side of the state isn't as good as the west side for toothies but there are a decent number of areas, mostly stocked with tigers. Might try exploring Nockamixon Lake, Marsh Creek Lake, Blue Marsh Lake, Delaware River, Lehigh River, and some sections of the Perkioman Creek or maybe the Skuke (check the PFBC site on Warm Water Stocking for which river sections are stocked). Wade fishing for summer muskies on lakes is tough as fish tend to be deeper. Springtime is better for the wading angler.
Rivers can be wade fished pretty good this time of year if you can get out in the middle or find a section without tree cover to snag your back cast. Muskie fishing is about persistence and covering as much water as possible. Pick a day, start early, and hit a couple different areas and drive from one to the next until you find a section of stream or lake that looks good and then fish that section thoroughly next time. River muskies in summer tend to bite best on days when the water has some stain to it and is rising. Blue bird days when the river is low and clear are tough (although good days to familiarize yourself with a river's structure).
