Abstract: During the past two decades there has been increasing resources expended on the restoration and enhancement of river and wetland ecosystems in the United States. More recently, increasing concern has been expressed by natural resource agencies and independent scientific reviews about the effectiveness of local restoration projects and the value of the cumulative effect of individual projects on the watershed aquatic ecosystem. Evaluation of these types of projects is complicated by the paucity of threatened and endangered species that these projects are designed to assist in recovery as well as the temporal and spatial variability associated with aquatic habitat requirements. The Red River Wildlife Management Area in Central Idaho has been developed as a research site to evaluate different restoration approaches and to develop performance evaluation methodology. A method is presented to link geomorphic analysis with sediment, water quality and hydrologic output from a river model with fish habitat needs.
