- Abstract:
- We conducted a radiotelemetry study of spring–summer Chinook salmon at Bonneville Dam to evaluate if modifications made at the Cascades Island (CI) fishway to facilitate passage of adult Pacific lamprey and reduce maintenance requirements adversely affected passage of adult salmon. This report compares Bonneville Dam passage time metrics and CI entrance use and passage efficiency metrics collected in April-May 2009 with similar metrics calculated using spring Chinook salmon data collected in 1997-1998, 2000-2004, and 2006-2007. It also compares passage time metrics and CI entrance use and passage efficiency metrics from June 2009 with similar metrics from summer Chinook salmon radio-tagged in June 2002–2004.
