On a trip to Northern Manitoba few years back we fished for walleye along with pike. We caught them until we got bored. For us California guys on the trip it was quite a novelty as none of us had ever seen a walleye before. Fast sinking lines with streamers: clouser minnows, Blanton's Whistlers, Lefty's Deceivers, and bunny leeches. When we were catching them they were from 10 to 25 feet below the surface. The fact that there was a zillion of them helped, as did having a guide.
