Re: minnesota trout fishing
Minnesota does have seasons.
You can fish trout from January 1st until September 30th I believe. It's all C&R during the winter months, so keep that in mind. They close it down for three months during the fall to allow for spawning to take place without people yanking fish off of the redds.
When you get to Minnesota, head to a local fly shop and pick up the DNR's 2011 map book which will show you all of the trout streams, as well as the public access available on those streams.
This coming year, from what I understand right now, will be the first with brand new regulations allowing C&R fishing on ALL designated trout waters, instead of just a select few that were open to winter angling. Verify this with the DNR before you head out after Jan. 1st, but the way it stands right now, the rules are going to go in effect by then.
