Mille Lacs' troubled waters defy quick fixes
Stocking Mille Lacs with new walleyes seems like a neat fix for a broken lake that is one of the natural touchstones that makes Minnesota — Minnesota.
It worked for Leech Lake. It worked spectacularly for Red Lake, when its walleye population collapsed in the 1990s.
But artificially adding fish to Mille Lacs next spring would probably quell only the human problem that’s arisen from a painful blow to the state’s fishing culture. The natural ones that lie below the lake’s notoriously rough surface are far more complicated, say fish biologists.
