Bridge Street Dam Fishway Design

Aluminum Stoplogs for AIS Control

Total Budget: $1,983,000 BSD Costs: $1,300,000 Remaining Budget: $683,000

•  Design required close coordina*on with US Army Corps of Engineers, Wisconsin DNR, Ozaukee County, USGS Con* Labs Research Facility, US Fish & Wildlife Service, Village of Grajon, consultants, and local residents

•  Novel design incorporates an adapta*on of stream simula*on technology – basically building a stream inside a large culvert. Closed sec*on changes to an open channel upstream.

•  Maintains or arguably reinforces AIS risk management, <2% slope, landowner preferences, upstream AND downstream passage

•  Replaces failing abutment, provides ability to drawdown reservoir, and tangibly increases spillway capacity


Bridge Street Fishway AIS/VHSv Concerns •  State determina*on of “Great

Lakes boundary” dam

•  Permit: ac*ve trap and sort, 30 day hold for VHSv tes*ng, lake sturgeon passage only

•  Village rejected the permit cannot afford opera*onal cost

PASSIVE FISHWAY NOT APPROVED “GREAT LAKES BOUNDARY” DAM

•  Village es*mated cost to repair dam: $1,100,000. Par*ally paid by WDNR grant funds.

Total Budget: $1,983,000 BSD Costs: $1,300,000 $211,000 Remaining Budget: $683,000 $1,772,000
