At the Council’s June 17, 2009 request the ISRP reviewed the Yakama Nation’s Columbia River Fish Accord proposal titled Upper Columbia Nutrient Supplementation (2008-471-00). The project is intended to assess and characterize nutrient availability. If needed the project proponents will perform controlled experimental addition of limiting nutrients to enhance natural production of anadromous salmonids and their supporting ecological functions and limnological conditions in rivers in the Methow Subbasin. This proposal includes some methods that are not appropriate and does not provide sufficient detail in other areas to enable an evaluation of scientific merit. The ISRP requests a response.
