Because of working like 70 hours a week I have not been out on the water yet GRRRRR however anyone I have talked with have said the same thing. Especially in the north. The walleye bite has been slow compared to a record year last year. It makes sense to blame it on the weather. Last year water levels where higher, water was colder, this year its complete opposite. April first we had high 20 low 30s degree days which melted ice up north way faster then then normal years, i believe most spawns are triggered by water temperture. So it makes sense that we are 3 or 4 weeks ahead of a normal year and fish maybe in there summer locations already.
Even when the bite is tough, it just means you may have to work for it a bit more. What i always do and always tell others to do is to go spend some money at the local bait shops. They always know how to get on fish even in tough times. They love your busienss and want you to catch fish so you will come back They are your best bet to find fish unless of course you want to dish out the cash for a guide
Cheers!
