Monitoring juvenile Chinook salmon outmigration using rotary screw traps on Butte Creek
The California Department of Fish and Wildlife (CDFW) conducts juvenile salmonid emigration monitoring on Butte Creek at the Parrot-Phelan Diversion Dam near Chico, California. Monitoring is conducted annually from October through June utilizing an 8-ft diameter rotary screw trap (RST) and a diversion screen trap (DST). Data from this monitoring is used to estimate juvenile spring-run Chinook salmon (Oncorhynchus tshawytscha) abundance and passage, identify alevin emergence timing, document juvenile size at emigration, and document rearing and emigration patterns. This 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. Salmonid data collected from the Butte Creek RST, among other datasets, is also used by the Salmon Monitoring Team (SaMT) to understand the movement of juvenile salmon in the Sacramento River Watershed to estimate the number of winter-run and spring-run Chinook salmon that have entered the Sacramento-San Joaquin Delta (Delta). SaMT is a real-time operations monitoring team required by Condition of Approval 8.1.2 of the ITP which meets weekly from October through June, to provide advice for real-time management of SWP operations to DWR, CDFW, and the Water Operation Management Team (WOMT) to minimize take of winter-run and spring-run Chinook salmon in the Delta. Note: data within the current year’s monitoring season are considered provisional.
Monitoring juvenile Chinook salmon outmigration using rotary screw traps on the Sacramento River near Tisdale Weir
The Tisdale RST sampling site is operated by the California Department of Fish and Wildlife (CDFW) to obtain information on the temporal distribution, relative abundance, and composition of race and species of juvenile Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss) emigrating from the upper Sacramento River and tributaries to the Sacramento-San Joaquin Delta (Delta). The project collects data near the Tisdale Weir on the Sacramento River, using two paired rotary screw traps (RSTs) outfitted with two 8-ft diameter cones. The RST monitoring site at Tisdale Weir was established meet a requirement of the 2011 amendment to the reasonable and prudent alternative (RPA) of the 2009 biological and conference opinion (BO) on the long-term operations of the Central Valley Project (CVP) and State Water Project (SWP). The amendment required the Bureau of Reclamation (USBR) and the California Department of Water Resources (DWR) to fund a new juvenile salmonid monitoring site on the Sacramento River between Red Bluff Diversion Dam (RBDD) and Knights Landing. The purpose of the new site was to provide early warning of fish movement and determine survival of listed fish species leaving spawning habitat in the upper Sacramento River. CDFW issued ITP 2081-2019-066-00 to DWR on March 31, 2020, for the long-term operation of the SWP in the Delta. Condition 7.5.2 of the ITP requires the development and establishment of a spring-run Chinook salmon juvenile production estimate (JPE) to increase understanding regarding the impacts water operations have on the spring-run Chinook salmon population in the Sacramento River watershed and inform the development of minimization measures to reduce take of spring-run Chinook salmon at Delta fish salvage facilities. Data from the Tisdale RST will be used along with other datasets from juvenile salmonid monitoring programs in the Sacramento River Watershed to inform the development of JPE modeling approaches.

Monitoring juvenile Chinook salmon outmigration using rotary screw traps on the Lower Feather River
CDFW issued Incidental Take Permit No. 2081-2019-006-00 (ITP) to the California Department of Water Resources (DWR) on March 31, 2020, for the long-term operation of the State Water Project (SWP) in the Sacramento San Joaquin Delta (Delta). Condition 7.5.2 of the ITP requires the development and establishment of a spring-run Chinook salmon (Oncorhynchus tshawytscha) juvenile production estimate (JPE) to increase understanding of the impacts that water operations have on the spring-run Chinook salmon population in the Sacramento River watershed and to inform the development of minimization measures to reduce take of spring-run Chinook salmon at Delta fish salvage facilities. As a part of the JPE effort, CDFW began operating a new rotary screw trap (RST) monitoring station on the lower Feather River near River Mile 17, approximately 1 mile downstream of Star Bend Park and Boat Ramp near Olivehurst, in January 2022. This RST location represents the lowest point in the Feather River Watershed where juvenile salmon are sampled with an RST prior to entering the Sacramento River and includes salmon emigrating from the Yuba River. The expanded juvenile monitoring effort will help resource agencies and water managers identify numbers of salmon emigrating from the Feather River Watershed and contributing to the spring-run Chinook salmon population entering the Delta. Monitoring is conducted annually from October through June utilizing a pair of eight-foot rotary screw traps (RST). Data collected at the Lower Feather River RST site provides information on the temporal distribution, relative abundance, and race composition of juvenile Chinook salmon; and temporal distribution and relative abundance of steelhead trout (O. mykiss) emigrating from the Feather River and tributaries, including the Yuba River, to the Delta. Salmonid data collected from the Lower Feather River RST, among other datasets, is also used by the Salmon Monitoring Team (SaMT) to understand the movement of ju
Redd survey data of Chinook salmon in the Feather River
Since 2014, the California Department of Water Resources (DWR) has conducted annual Chinook salmon redd surveys. The objective of this data collection effort is to quantify and understand potential shits in redd distribution and potential habitat differences between historic and restored sites. The redd surveys are conducted in the uppermost 16 miles of the lower Feather River though have been concentrated in the uppermost two miles of the lower Feather River in, and adjacent to the Gravel Supplementation Areas (GSAs). Redd surveys are conducted less frequently in the 14 miles downstream of the GSAs. Surveys typically begin in mid-September at the onset of spawning and generally conclude at the end of November. This dataset represents an extensive time series that could be used to identify habitat conditions where Chinook salmon spawn, how these conditions have changed over time, especially in areas where restoration has occurred. These data were published to support the Healthy Rivers and Landscapes Program.

Monitoring juvenile Chinook salmon outmigration using rotary screw traps on Feather River
California Department of Water Resources (DWR) currently operates multiple eight-foot rotary screw traps (RSTs) in both the Low Flow Channel (LFC) and High Flow Channel (HFC) of the upper 21.5 river miles of the Lower Feather River. The LFC extends from the Fish Barrier Dam at river mile (RM) 67.2 to the Thermalito Outlet (RM 59). The HFC extends from the Thermalito Outlet to the confluence with the Sacramento River. This survey has been ongoing since 1997 with the objective of documenting general salmonid emigration attributes, such as timing, abundance and composition of salmon and investigating the influence of environmental factors thought to initiate emigration, such as flow, turbidity and water temperature. Data from this monitoring 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 Incidental Take Permit No. 2081-2019-006-00 issued by CA Department of Fish and Wildlife (CDFW) to DWR for the long-term operation of the State Water Project. Data within the current year’s monitoring season are considered provisional.
Monitoring juvenile Chinook salmon outmigration using rotary screw traps on the Sacramento River at Knights Landing
Since 1995, the rotary screw traps (RSTs) at Knights Landing have provided water management agencies an early warning of emigrating juvenile Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss) making their way to the Sacramento-San Joaquin Delta (Delta). Due to the proximity of the site to other major tributaries of the Sacramento River, such as the Feather and American Rivers, it is assumed that salmonids captured at the Knights Landing RSTs originate from the upper Sacramento River and its tributaries, a stretch of river that provides spawning and rearing habitat for all four runs of natural origin Chinook salmon: winter-run (State and federally listed as endangered), spring-run (State and federally listed as threatened), late fall-run and fall-run, as well as steelhead trout (federally listed as threatened). The near real-time information RST monitoring data provides on emigration timing and relative abundance for protected runs of juvenile Chinook salmon and steelhead improves the ability for resource agencies and water managers to implement protective measures that help them navigate through the maze of waterways in the Delta. By utilizing emigration data in adaptive management, reservoir releases, export rates, water transfers, and Delta Cross Channel Gate operations can be modified to minimize the risk of predation, entrainment, and take, thereby maximizing juvenile salmonid survival through the Delta. The primary goals of the Knights Landing Monitoring Program are to (1) Provide early warning of listed salmonids emigrating toward the Delta, (2) Document passage of emigrating salmonids including timing, relative abundance, and environmental conditions, (3) Develop passage estimates of salmonids emigrating through the lower Sacramento River above the Delta, and (4) Develop a long-term dataset on juvenile salmonid emigration to compare changes over time. The California Department of Fish and Wildlife (CDFW) issued ITP 2081-2019-066-00 to D
Monitoring juvenile Chinook salmon outmigration using rotary screw traps on the Sacramento River near Delta Entry
The California Department of Fish and Wildlife (CDFW) issued Incidental Take Permit No. 2081-2019-006-00 (ITP) to the California Department of Water Resources (DWR) on March 31, 2020, for the long-term operation of the State Water Project (SWP) in the Sacramento San Joaquin Delta (Delta). Condition 7.5.2 of the ITP requires the development and establishment of a spring-run Chinook salmon (Oncorhynchus tshawytscha) juvenile production estimate (JPE) to increase understanding of the impacts that water operations have on the spring-run Chinook salmon population in the Sacramento River watershed and to inform the development of minimization measures to reduce take of spring-run Chinook salmon at Delta fish salvage facilities. As a part of the JPE effort, CDFW began operating a new rotary screw trap (RST) monitoring station on the lower Sacramento River near River Mile (RM) 75, approximately 5 miles below the confluence of the Feather and Sacramento Rivers, in January 2022. This RST location represents the lowest point in the Sacramento River Watershed where juvenile salmon are trapped prior to entering the Delta and thus is also referred to as the “Delta Entry” site. The expanded juvenile monitoring effort will help resource agencies and water managers identify numbers of salmon emigrating from the Sacramento and Feather River watersheds and contributing to the spring-run Chinook salmon population entering the Delta. Data collected by the RST site at the Lower Sacramento River provides information on the temporal distribution, relative abundance, and race composition of juvenile Chinook salmon; and temporal distribution and relative abundance of steelhead trout (O. mykiss) emigrating from the upper Sacramento River and Feather River to the Delta. Salmonid data collected from the Lower Sacramento River RST, among other datasets, is also used by the Salmon Monitoring Team (SaMT) to understand the movement of juvenile salmon in the Sacramento River Watershed to estimate th
Monitoring juvenile Chinook salmon outmigration using rotary screw traps on Yuba River
California Department of Water Resources (DWR) currently operates multiple eight-foot rotary screw traps (RSTs) at Hallwood Boulevard RM 7.5. RST operations were conducted by CDFW and then under the direction of the Yuba River Management Team from 1999 to 2009 at the Hallwood Boulevard site; and resumed in 2022 by DWR. The Hallwood site will essentially sample all areas of the lower Yuba River upstream of Hallwood Boulevard. Additionally, the Hallwood site is located downstream of the bulk of adult Chinook salmon spawning areas and downstream of all known spring-run Chinook salmon spawning. Data are currently being used to inform the development of a juvenile production estimate (JPE) for spring-run Chinook salmon in the Sacramento River Watershed as required by Incidental Take Permit No. 2081-2019-006-00 issued by CA Department of Fish and Wildlife (CDFW) to DWR for the long-term operation of the State Water Project. Data within the current year’s monitoring season are considered provisional.
Anatoxin concentrations, algal assemblages, and water quality data for the South Fork Eel, Salmon, and Russian Rivers in northern California, 2022-2023
We collected this data to better understand the timing of peak benthic cyanobacterial mat occurrence (specifically taxa associated with anatoxin production, Microcoleus and Anabaena) and mat anatoxin concentrations in rivers. We sampled in northern California on the South Fork Eel, Salmon, and Russian Rivers biweekly in 2022, and the Salmon River biweekly and South Fork Eel weekly in 2023. During each sampling event, we conducted benthic cover surveys, measured in-situ water quality parameters (temperature, pH, dissolved oxygen, conductivity), and collected surface water samples and targeted cyanobacteria samples. In 2022 on all rivers and in 2023 at the Salmon River, we also collected distributed non-targeted periphyton samples to characterize full-reach community compositions. All sampling was completed in 150-m reaches upstream of sensors recording continuous dissolved oxygen, conductivity, and temperature data. We analyzed surface water samples for nitrate, ammonium, soluble reactive phosphate, total dissolved carbon, and dissolved organic carbon. We also analyzed surface water samples from 2022 for major anions (Cl, SO4, Br) and cations (Na, K, Mg, Ca). Targeted-cyanobacteria and non-target periphyton samples were analyzed for anatoxins (and two other classes of toxins, microcystins and cylindrospermopsins), relative abundance of algal taxa (via microscopy), ash-free dry mass, and chlorophyll-a. To estimate mean river depth within the dissolved oxygen footprint upstream of sensors, we kayaked portions of the river and collected river depth measurements. We also measured discharge at each river excluding the Salmon River (due to high discharge) and completed pebble counts at the South Fork Eel River to obtain sediment grain size distributions. Lastly, we estimated daily reach-scale river metabolism (gross primary productivity and ecosystem respiration) using data from dissolved oxygen sensors with the "streamMetabolizer" package in R at all sensor placements.
Hydrodynamic Model Output Used to Evaluate Chinook Salmon Movements and Distribution in the South Delta
This data release includes the output variables extracted from the UnTRIM Bay-Delta hydrodynamic model (hydrodynamic model) for use in evaluating the effects of hydrodynamics on the behavior of acoustically-tagged juvenile Chinook Salmon (Oncorhynchus tshawytscha) in the Sacramento-San Joaquin Delta. Work was funded by State Water Contractors (SWC) and completed by Anchor QEA; FlowWest, LLC; and University of Washington under a SWC 2023 Science Plan grant (study name Evaluation of the Influence of State Water Project and Central Valley Project on Chinook Salmon Movements and Distribution in the South Delta), contracted by SWC. Not all the hydrodynamic model output variables in the output provided with this memorandum were used in the final fish models used to analyze Chinook Salmon responses. Model output for additional variables and locations were included for completeness and to make these output files more broadly useful to researchers interested in other locations or variables in the Sacramento-San Joaquin Delta. Hydrodynamic model simulations were conducted for 2010, 2011, 2012, 2013, 2014, 2015, 2016, and 2017, with hydrodynamic model output variables provided at mostly the same locations for each period simulated. The years 2011 through 2016 were simulated previously for a prior project and model output provided through the Environmental Data Initiative (edi.1124.1). Files for these years were recreated from the prior simulations for this project to add an output location. Additional locations were added to the 2010 and 2017 simulations for the 2010 and 2017 hydrophone arrays, and thus 2010 and 2017 include additional model output, relative to 2011 through 2016. The model simulation for each year spanned the full period of Chinook Salmon detections in the telemetry data collected during that year.
Relative predation rates on juvenile Chinook Salmon in the lower Stanislaus River, California, 2012-2024 by habitat suitability informed by juvenile Chinook Salmon and black bass observations in the lower Stanislaus and Merced rivers, California, 2012-2017
Overview The purpose of this work was to estimate relative predation on juvenile Chinook Salmon rearing in tributaries of the San Joaquin River, California in relation to meso- and microhabitat factors. Predation rates were estimated using predation bioassays. Ranges of depth and velocity targeted by the bioassays were informed by habitat suitability indices developed prior to field efforts. Juvenile Chinook and Bass Habitat Suitability Indices The purpose of this dataset is to develop habitat suitability indices for juvenile Chinook Salmon (<120mm) on the lower Stanislaus River and nonnative black bass ( Micropterus spp.). on the lower Merced River, both tributaries of the San Joaquin. This data was used to identify target ranges of depth and velocity during predation fieldwork. Occupancy data was collected via snorkel surveys on the lower Stanislaus River in 2018 and 2019 and on the Merced River in 2012 and 2014-2017. Predation Tethering Bioassay Study The purpose of this field study was to estimate relative rates of predation of juvenile Chinook Salmon. Predation rates were estimated using assays of tethered hatchery Chinook Salmon deployed across a range of mesohabitats on the lower Stanislaus River. Habitat suitability was expected to vary across mesohabitats and across depths and velocities sampled within habitats. Cameras were deployed with tethers to identify predators for a subset of predation events happening within the first 1-2 hours of deployment. Assays were deployed monthly March-May in 2022 and 2024. A supplemental set of assays were deployed in May 2023 under wet water year conditions that varied strongly from conditions sampled in 2022 and 2024.
2021-2024 Juvenile Chinook Salmon Rearing and Growth on the Lower American River, California
The primary goal of the Central Valley Project Improvement Act is to at least double natural production of Chinook Salmon ( Oncorhynchus tshawytscha ) in California Central Valley (CCV) streams on a sustainable basis. Beginning in 2008, semi-annual gravel augmentation and off channel habitat enhancement projects were implemented on the Lower American River (LAR) by Reclamation and USFWS, in partnership with the Sacramento Water Forum, as part of the LAR habitat enhancement program. The overall vision for the habitat enhancement program is to restore ecosystem processes by rehabilitating and enhancing critical channel, floodplain, and riparian habitats for juvenile and adult anadromous salmonids, thus promoting the recovery of healthy and diverse Chinook Salmon and steelhead ( O. mykiss ) populations. Off channel rearing habitat has been identified as a limiting factor in meeting CCV salmon population goals. While numerous studies have documented positive relationships between off channel habitat and juvenile rearing on the LAR, it is not known how long juveniles remain in off channel habitat compared with the main channel, whether rearing in off channel habitat enhances growth compared with the main channel, whether the relative value of off channel habitat for juvenile production depends on how long it has been inundated, or whether juvenile diet in off channel habitat differs from that in the main channel. To better understand these relationships, we conducted a mark-recapture study under a range of hydrological conditions between 2021-2024 using passive integrated transponder (PIT) tagged wild juvenile Chinook Salmon coupled with seining surveys at five off channel restoration sites on the LAR designed for rearing, as well as nearby main channel control sites that were also suitable rearing habitat. First, we investigated whether side channel habitats in restored reaches support higher Chinook Salmon densities than main channel control habitats. Density was estim
Monitoring juvenile Chinook salmon outmigration using rotary screw traps on Deer and Mill creeks
The California Department of Fish and Wildlife (CDFW) conducts juvenile salmonid emigration monitoring on Mill and Deer Creek (Tehama County, CA) annually from October through June using rotary screw traps (RSTs). Data from this monitoring is used to estimate juvenile spring-run Chinook salmon (Oncorhynchus tshawytscha) (spring-run) abundance and passage, identify yearling outmigration timing and alert resource agencies of juvenile spring-run presence in the lower Sacramento-San Joaquin Delta. This data will be included in the development of a juvenile production estimate (JPE) for spring-run Chinook salmon in the Sacramento River 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. Salmonid data collected from the Mill and Deer RSTs, among other datasets, is also used by the Salmon Monitoring Team (SaMT) to understand the movement of juvenile salmon in the Sacramento River Watershed to estimate the number of winter-run and spring-run Chinook salmon that have entered the Sacramento-San Joaquin Delta (Delta). SaMT is a real-time operations monitoring team required by Condition of Approval 8.1.2 of the ITP which meets weekly from October through June, to provide advice for real-time management of SWP operations to DWR, CDFW, and the Water Operation Management Team (WOMT) to minimize take of winter-run and spring-run Chinook salmon in the Delta.
Monitoring adult Chinook salmon upstream passage on Yuba River
Adult salmonid data on the Yuba River is collected and managed by the Yuba Water Agency and the California Department of Water Resources. Upstream passage data is collected year-round at Daguerre Point Dam, 24 hours a day and 7 days a week. Data from this monitoring is modeled by Brian Poxon and Paul Bratovich to produce estimates of adult escapement (upstream passage) abundance. 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.

This data package is complimentary to edi.1504 and represents current RST monitoring on Deer and Mill creeks. Data within the current year’s monitoring season are considered provisional.
Genetic assignments for Spring Evolutionary Significant Unit reanalysis, Central Valley Chinook Salmon populations, CA, 2011-2024
Central Valley Chinook Salmon populations differ in their Endangered Species Act listing status. It is difficult to visually distinguish individuals from the different Evolutionarily Significant Units (ESU). As such, many of the salmon monitoring and evaluation efforts in the Central Valley and San Francisco Bay-Delta are hampered by uncertainty about population (stock) identification and proportional effects of management actions (Dekar et al. 2013; IEP 2019). Studies have identified that the current identification method (length-at-date models) of juvenile Chinook salmon (Fisher 1992) captured in the watershed vary in their accuracy, particularly for spring-run (NMFS 2013; Harvey et al. 2014; Merz et al. 2014). The inaccuracy of the size-based methods is likely due to differences in fish distribution during early rearing, habitat-specific growth rates, and inter-annual variability in temperatures and food availability that lead to overlap in size ranges among stocks. The primary objective of this project was the genetic classification (to genetic lineage; Evolutionary Significant Unit) of Chinook Salmon captured from State Water Project and Central Valley Project fish protection facilities and Interagency Ecological Program compliance monitoring programs. The genetic lineage was determined for sampled fish by comparing their genotypes to reference genetic baselines. Genetic methods, having less statistical uncertainty that size-based models for population identification, were intended to directly target (and reduce) one source of uncertainty in the estimation of loss (take) from water diversions (operations) and develop the information necessary for understanding stock-specific distribution, habitat utilization, abundance, and life history variation. This project supports recommendations from the Interagency Ecological Program’s Salmon and Sturgeon Assessment of Indicators by Life Stage and Interagency Ecological Program Science Agenda efforts to improve Central V
Sonde Data (2010-2014) from the Salmon Trout River in the Huron Mountains, Marquette Co., Michigan.
This dataset includes readings from a multi-parameter water quality sonde to continuously monitor chemical and biological conditions (water temperature, conductivity, dissolved oxygen, pH, turbidity) on the Salmon Trout River in Marquette, MI. This sensor was deployed May-Nov 2010, 2011, 2012, 2013 and 2014. This dataset includes cleaned raw data obtained with the sonde and may include time periods when readings were affected by sand accumulation/burial of the sensors.
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.
Chinook Salmon genetic assignments for the Central Valley Project (CVP) and State Water Projects (SWP), Sacramento and San Joaquin Delta Waters, CA, 2024-25
