Grindstone Lake between Hinckley and Sandstone MN has a smelt run. I have not been there smelting in 9 years so you would have to do some checking on when there running up the river. The most common place is from the public access and there are usually a few people there.
People who fish for food, and sport be damned, are called pot-fishermen. The more expert ones are called crack pot-fishermen. All other fishermen are called crackpot fishermen. This is confusing. ~ Ed Zern, 1947
