I didn't know if anyone else knew this but since Jan 1st of '19 you now need an additional permit that costs $25 to fish Wanahoo unless you live in the Wahoo area....
The Nebraska Game and Parks Commission, which has co-managed the lake and its surrounding recreation area since Lake Wanahoo opened in 2012, is turning over operations to the Lower Platte North Natural Resources District, which owns the 1,777-acre property. The transition begins Oct. 16, 2018 but state park entry permits will continue to be honored there until Dec. 31, 2018 when the co-management agreement expires.
That is in addition to the Park permit.....
