Hey there, I have been fishing in and around SE Minnesota and I'm not having much luck, just wondering what sort of flies are working around here?

Any help will be very much appreciated

Thank you!

http://www.minnesotaflyfishing.com/ has some info on the flys . you can also check out
http://mnflyfishing.com/ check out the hatch chart info and you can also ask in the forums

90 percent of the time they feed subsurface so Nymphs streamers and emergers will be your best shots.

some good nymph s are the pheasant tail nymph , the hairs ear nymph ,pink squirrel, copper john . wooly buggers

Consider getting these books...

This is a hatch chart for SW Wisconsin....SE Minn should be quite similar.
