Estimated potential
production of three Lake Huron fishes in the Au Sable River between Mio and Foote
dams
•Whelan estimated >5 ft/mi gradient on a 1000+ cfs river would support
adult lake
sturgeon runs of 1900 fish per mile (Thuemler 1985; Auer 1995; Auer 1996).
•Estimated production from a 4.6 ft/mi gradient reach on Manistee River was 887,000 June YOY chinook
salmon and 24,800 September YOY steelhead per mile (Rutherford et al.
1997)
