I think Pelican is one of the rare lakes where there is just too much forage at the moment and it makes the fishing tough. The perch population is high and there's also a large population of trout-perch and shiners that are a main forage for walleye in the lake (according to dnr guys I've talked to in past). Every walleye I kept over the winter had stomachs bulging with perch. Even the perch were tough to catch, even though I was constantly on top of them. And every perch I kept had a belly bulging with insects. If you're not out there fishing in low light you're going to really struggle to catch walleye. And even if you are fishing low light, its going to be a struggle. The population was estimated a couple years ago at 4-5 adults/acre, which means there were roughly 16-18k adult walleye, so the population is there and thriving. But why would the walleye bite our baits when they are constantly surrounded by and full of their preferred forage?
That's my opinion and I've fished the lake since the years when the walleye population was low.
