There is definitely good shore fishing access below the dam. You could potentially catch all the species you mentioned at any time. I typically fish at night, but the low light hours of the day are good also. I mainly fish walleye, but catch Muskie with regularity. Almost 1 per trip this year, and I went 5 times. I have caught up to 5 in one night up to 42", and lost and seen a few caught that have hit the 50" mark.
Fishing the rocks is most productive for me, but can be very dangerous, and slippery. BE carefull!! I wear a life vest at night fishing alone. You can also put on waders, and walk the shore down towards route 21. Plenty of shore to fish, and a bait shop for your needs.
