When you fish Lake Erie in April you have be prepared for anything. Bring rain gear and clothing for both warmer (50's) and colder weather. You can catch the best walleye of your life that time of year but you may have to tough it out as far as the weather. Trust me, I have seen it all. We have operated a fishing camp out of Port Clinton for generations and some of my best fishing has been in April. Neoprene gloves will help you if it gets cold. They fit like a second skin so you can still work with your lures and bait without having to take your gloves off all the time. Good luck and tight lines.
