The Oneida Tribe of Indians of Wisconsin retained Ayres to design improvements to the Duck Creek fisheries by removing obstructions to desirable fish passages and providing barriers to undesirable fish movement. Critical to meeting these goals was modifying Dam 1 at Oneida Golf & Country Club in Green Bay and removing Dams 2 and 3 at Pamperin Park in Howard, Wisconsin.
Ayres provided design and engineering services and permitting assistance to support efforts by the Wisconsin Department of Natural Resources, U.S. Fish and Wildlife Service, and other stakeholders to improve Duck Creek. This involved developing undesirable fish movement barrier alternatives at Dam 1, designing modifications to Dam 1 and removal of Dams 2 and 3, completing a hydraulic evaluation of the effects of the dam modifications, preparing construction cost estimates, and coordinating permit submittals.
The modifications at the Golf & Country Club dam involved installing walls along the bank to help stop the migration of the round goby, an invasive species, while allowing the migration of northern pike, suckers, and other desirable fish coming from Green Bay.
