I live in northern WI and I was wondering when some species of fish spawn. The weather up here has been pretty nice lately but we had a really cold winter. I mostly want to know when the Northern Pike, Largemouth Bass and Bluegill spawn. Thanks for any help.

Northern pike have already spawned. Bass will probably be on the beds in about 3 weeks, depending on what kind of weather happens. Muskies are spawning right now. Bluegills will be spawning in 3 or 4 weeks

About how deep of water do you think the pike bass and bluegill are going to be in?

The northerns have already spawned. They can spawn under the ice but a lot of times it's shortly after up until the water hits about 50 degrees. Largemouth will start to move up into spawning areas when the water hits 58-ish degrees and will start spawning in the mid to upper 60's. Bluegills generally spawn shortly after the LM bass do. They can also spawn multiple times a year but the first spawn is usually the biggest. I don't know exactly how far north you are, but I'm about an hour north east of Eau Claire and last night the water on a stained lake was 57. If the lake is clearer it won't usually warm up as fast and also the farther north you go it won't be as warm either. As for depth they spawn at, usually anywhere from a foot down to about 7. It depends on the lake and the conditions. Usually bluegills will be the shallowest. You'll be able to see large groups of beds unless the water is pretty heavily stained. 

I was wondering what depth you think the fish would be at right now?
