Monitoring adult spring-run Chinook salmon throughout the adult lifespan on Deer and Mill Creek

The California Department of Fish and Wildlife (CDFW) collects data on adult salmonids on Deer Creek and Mill Creek. Data is collected annually via redd surveys on Mill Creek and holding surveys on Deer Creek; video camera systems on both creeks collect data on upstream passage 24 hours a day, 7 days a week from February to August. Data from this monitoring is used to estimate adult escapement (upstream passage) abundance and timing, spawner abundance, and other important metrics for adult salmonids in the watershed. These data will also be used to inform the development of a juvenile production estimate (JPE) for spring-run Chinook salmon in the Sacramento River Watershed as required by Condition of Approval 7.5.2 of Incidental Take Permit No. 2081-2019-006-00 (ITP) issued by CDFW to California Department of Water Resources (DWR) for the long-term operation of the State Water Project. ## About This Federated Record This CNRA Open Data Platform record is based on metadata federated from the Environmental Data Initiative (EDI) Data Portal. Its purpose is to improve the discoverability of the data package through the CNRA Open Data Platform. The EDI Data Portal is the repository of record for this data package. Metadata, resource links, and supporting information displayed here may not reflect the latest updates available in EDI.
