No fishing will be allowed during these periods in the specified areas. Signs will be posted at access points within the closed areas.

"The closures are necessary to protect adult walleye that have concentrated around historic spawning sites," said Henry Drewes, DNR Northwest Region fisheries manager. "It's always a difficult decision to close the areas and restrict recreation. Our first responsibility is to the long-term health of the fishery."

This is the first time since 2008 that so many locations have been closed on the opener, Drewes said. Prior to that, extensive closures occurred in 1996 and 1997. There are likely to be concentrations of spawning fish in other areas and anglers are encouraged to practice catch-and-release.

Although closed to fishing, there are no restrictions on boat travel through these areas.
