The Great Waters Fly Fishing Expo, the Midwest's largest fly fishing event, will be held this weekend over three days, beginning Friday at Hamline University Walker Fieldhouse.

Fly shops, guides, top brands, outfitters and nonprofits will exhibit, along with representatives from fly fishing destinations in the Midwest and West. The show's emphasis is on fly fishing education, and free programs, seminars, casting demonstrations and fly tying instruction will be offered.

Proceeds will benefit habitat work undertaken by Minnesota Trout Unlimited.
