Background Permit 181814R
CDFW is seeking to renew an enhancement permit under section 10a1A of the ESA for a period of 5
years that would allow take of both adult and juvenile Sacramento River winter-run Chinook salmon, CV springrun Chinook salmon, CCV steelhead, and sDPS North American green sturgeon in the Sacramento River and its tributaries. This permit renewal would cover four monitoring and rescue efforts carried out by CDFW: 1 Juvenile emigration monitoring, 2 adult trapping for the Steelhead Monitoring Program, 3 Upper Sacramento River restoration site monitoring, and 4 fish salvage and rescue operations.
Each project has its own objectives.
The Juvenile Emigration Monitoring will take place at Tisdale Weir, Knights Landing, the Feather River High Flow Channel, and the Delta Entry sites, with the goals to monitor juvenile salmonid outmigration in real time, provide summaries of timing, abundance, and size distribution, provide timing information to water agencies for better management decisions, and evaluate how environmental conditions flow, temperature, turbidity affect downstream movement. The objectives of the Central Valley Steelhead Monitoring will be conducted to estimate the steelhead population abundance, examine trends in abundance, and identify spatial distribution over time. The Upper Sacramento River Restoration Site Monitoring aims to evaluate the outcome of the Central Valley Project Improvement Act Section 3406b13
gravel augmentation and restoration projects through documentation of spawning activity, relative abundance of juvenile salmonids using the restored habitat, habitat attributes and quantities in restored sites, and habitat conditions and fish presence in control and preand post-construction sites. Efforts associated with the Central Valley Fish Rescues will involve the collection, tagging, and relocation of entrained listed salmonids and sDPS green sturgeon at the fish collection facility at Wallace Weir, the Colusa Basin Drainage Canal, behind Fremont and Tisdale weirs, the Sacramento River, Deer Creek, Mill Creek, Antelope Creek, and various urban streams. The rescue

program also assesses the magnitude of stranding and aims to document conditions resulting in high levels of stranding. CDFW staff will also monitor winter-run Chinook salmon redds that are at risk of being dewatered. In the event that a redd is likely to be dewatered, CDFW staff may physically modify the redd by hand to prevent complete dewatering and increase the likelihood of survival.
Under the various studies, juvenile salmonids and smolts would be observed via snorkel and video surveys and captured using rotary screw traps and beach seines. In addition, juvenile salmonids would be handled:
Anesthetized, measured, checked for marks or tags, tagged acoustic tags for spring-run Chinook salmon, passive integrated transponder PIT tags for steelhead, and elastomer tags for salmonids used during rotary screw trap efficiency trials, sampled for tissues, and released. A subsample of hatcheryorigin adipose fin clipped winter-run Chinook salmon and spring-run Chinook salmon juveniles and smolts would be sacrificed for coded wire tag CWT retrieval and analysis. In the case of rescues and relocations, fish may be collected and transported either via foot or transport truck, depending on the distance to the release location to more suitable habitat prior to release.
Adult salmonids would be observed via snorkel, video, or spawning surveys and captured using beach seines, fish weirs, and fyke traps. Adult steelhead may also be captured in rotary screw traps. In addition, adult salmonids would be handled as follows:
anesthetized, measured, checked for marks or tags, tagged floy tags for all adult salmonids, as well as PIT tags for steelhead, and acoustic tags for both springand winter-run Chinook salmon, sampled for tissues, and released. Tissues would be collected from any carcasses encountered.
Juvenile, subadult, and adult green sturgeon would be captured via hoop nets and fyke traps, anesthetized, tissue sampled, tagged PIT or acoustic, and released. Additionally, juvenile green sturgeon may be captured in rotary screw traps and adults may be encountered during monitoring at weirs.
Subadult and adult green sturgeon would also receive floy tags. Adult sturgeon may also be collected and transported live to more suitable habitat during rescue activities.
With the exception of the juvenile salmon CWT retrieval above, the researchers are not proposing to kill any of the fish being captured, but a small number of fish may be incidentally killed as an inadvertent result of these
