Jacksgp, walleye fishing in a reservoir is pretty much the same as lake fishing. Walleye are usually associated with underwater structure, they like land point near drop offs, stone rip-rap on a dam face, sunken islands, flooded creek channels and weed growth. Walleye have very well developed eyes for seeing in low light conditions, as such they feed most actively just before sunrise and just at sunset. They still can be caught during the day, though there strike zone will be smaller, In the heat of the day they like to be in the shadows,{easier on there sensitive eyes} be it rock piles or weed growth, and wait for prey to swim by. If your reservoir has a large algae bloom then the fish will be active all day long.
Walleye tend to school with fish of there own size, so if you are in an area and you get a larger fish, try drifting or trolling a few more times through it, chances are you will get another larger fish.
Lures for walleye can really vary, you have to take in for account the time of day, weather, algae bloom and forage present in the body of water. I have found walleye tend to like the brighter colors of lures and jigs, colors like fire tiger, white, red, orange, chartruse and yellow all work well. The good old Mr.twister, or Berkley curly tail work well as do swim baits, crankbaits and live or frozen bait.
When fishing from a row boat I would add a rod holder near the back of the boat, that way you can row with out hitting the rod and watch for a strike, plus the rowing motion should give a lure a neat stop and go action that walleye like.
I hope this helps, Good Fishing
