1. InCom Working Group 127 Fish Passes Mark Cornish U.S. Army Corps of Engineers Rock Island District PIANC USA Annual Meeting 15 July 2008

2. Final Product Bottom Line Up-Front Document existing practices for the current state-of-the-science for fish passages that will aid designers when building and modifying existing locks and dams

3. One Team: Relevant, Ready, Responsive and Reliable Matters to be Investigated 1.Structural and non-structural fish passage methodologies 2.Effective bioresponse monitoring techniques for quantifying success 3.Biological and hydraulic computer simulations techniques 4.Requirements of migratory fish species on connectivity, habitat availability 5.Computer simulation techniques for predicting logitudinal connectivity (systemic changes) 6.Compare cost and economic benefit taking into account size of river and height of dam 1.Structural and non-structural fish passage methodologies 2.Effective bioresponse monitoring techniques for quantifying success 3.Biological and hydraulic computer simulations techniques 4.Requirements of migratory fish species on connectivity, habitat availability 5.Computer simulation techniques for predicting logitudinal connectivity (systemic changes) 6.Compare cost and economic benefit taking into account size of river and height of dam

Compare cost and economic benefit taking into account size of river and height of dam

20. Compare cost and economic benefit taking into account size of river and height of dam How much flow will be needed? How wide should it be? Will a fishway affect navigation? How can the design be optimize for fish? What size does the stone need to be?
