- Abstract:
- In 2010, we conducted a second year of radiotelemetry studies 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 2010 with similar metrics calculated using spring Chinook salmon data collected in 1997-1998, 2000-2004, 2006-2007 (pre-modification years), and 2009 (post-modification). It also compares these same metrics from June 2010 with results from summer Chinook salmon radio-tagged in June 2002–2004 and 2009.
