Nisqually Chinook Salmon and Steelhead Recovery Monitoring

This project will enable the Nisqually Tribe to conduct watershed scale effectiveness monitoring (priority 2) by collecting critical adult and juvenile Chinook VSP data through in-river trapping activities, spawning grounds surveys, and juvenile sampling throughout the Nisqually River and estuary. Adult live salmon counts will occur through trapping activities from July-November. The spawner surveys (i.e. live counts; and redd and carcass surveys), will generally from August to March and are inclusive of all salmon species. These surveys occur in the mainstem Nisqually River and Mashel (Nisqually Tributary) from the mouth to RM 3.5. Additionally, steelhead and other salmon counts will occur at the Centralia diversion fish ladder via a camera and sonar unit which requires oversight to ensure all necessary equipment is operational. Juvenile monitoring will consist of beach seining. This work will occur in the Nisqually nearshore/estuary and from the mouth of the Nisqually River to RM 3 during the months of February-October. The project primarily provides salary support for approximately 1 FTEs of tribal biologist time.

This project provides critical stock recovery information that assists in estimating changes to Nisqually Chinook VSP parameters as a result of harvest, hatchery, and habitat actions. The watershed scale monitoring components include: hatchery and natural Chinook distribution, abundance, and composition on spawning grounds; hatchery and natural composition in fishery; hatchery and natural composition in hatchery; and adult and juvenile Chinook life history diversity, age, and stock composition through genetic analysis (note: the analytical work is not funded by this project); juvenile Chinook distribution and abundance in recovering Nisqually Estuary. Additionally, the project will enable the Tribe to track steelhead adult abundance and distribution throughout the watershed.
