The October 2011 decommissioning of Condit Dam on the White Salmon River at river kilometer (rkm) 5.3 removed a significant fish passage barrier from the White Salmon River basin for the first time in nearly a century. This affords an opportunity to regain a potentially important drainage basin for Pacific lamprey (Entosphenus tridentatus) production. In anticipation of Pacific lamprey recolonization or reintroduction, aquatic resource managers, such as the Yakama Nation (YN), are planning to perform surveys in the White Salmon River and its tributaries. The likely survey objectives will be to investigate the presence of lamprey, habitat conditions, and habitat availability. In preparation for this work, a compilation and review of the relevant aquatic habitat and biological information on the White Salmon River was conducted. References specific to the White Salmon River were collected and an annotated bibliography was produced including reports containing:
•Spatial information about where various habitat surveys or monitoring have occurred over the past 20 years;
•Database information relevant to habitat attributes (for example, pools, riffles, or glides);
•Riparian surveys along major tributary streams;
•Water temperature and sediment information;
•Lamprey surveys, observations, and collections;
•Spawning gravel surveys; and
•Surveys that inventory habitat degradation or other environmental factors that may limit potential future productivity of lamprey.
