The Council’s 2009 amendments to the Columbia River Basin Fish and Wildlife Program call for the continuation of the fish passage related functions currently conducted by the Fish Passage Center. The primary functions are to provide technical assistance and information to fish and wildlife agencies in particular, and to the public in general, on matters related to water management, spill, and other passage measures. The Program also calls for the Fish Passage Center’s Oversight Board to ensure that the functions are implemented consistent with the Program. To do this, the Program specifies that the Oversight Board will work with the Center and the Independent Scientific Advisory Board (ISAB) to organize a regular system of independent and timely science reviews of the Center’s analytical products. This regular system of reviews includes evaluations of the Fish Passage Center’s draft annual reports, which began last year with our review of the Fish Passage Center’s 2009 draft Annual Report (ISAB 2010-4). Our review of the Fish Passage Center’s draft 2010 Annual Report follows below.
