I'm from Thunder Bay Ontario. I love walleye and smallie fishing.....well I'll fish for anything....
I was reading the post spawn walleye thread. Two tips:
Go with huge bait. I use 6-8 inch sucker minnows.
Fish shallow. The lakes that I fish you can sight fish for female walleye in the 5-14 lb range. Common mistake is to fish summer depths in the spring. These fish are in less than five feet of water "sunning" themselves. This window of oportunity is very small. Sunlight doesn't affect them it seems. Fishing at night is great to. This is one of the best times to haul in a huge one.
Try it.
