Long-term adult and juvenile periwinkle snail (Littoraria irrorata) density in mid-marsh and creekbank plots from the Georgia Coastal Ecosystems LTER Fall Monitoring Program

This data set includes long-term observation of the abundance of periwinkle snail (Littoraria irrorata) at sampling sites within the Georgia Coastal Ecosystem (GCE) LTER study area. Visual counts of adult Littoraria were conducted within 0.5m x 0.5m quadrats in-line with permanent GCE vegetation plots. Juvenile Littoraria (1-4mm shell length) were found and counted by looking inside all leaf furls within a nested quadrat (0.25m x 0.25m). In each marsh zone at each GCE LTER permanent monitoring site, we counted the number of adult and juvenile snails in 8 creekbank and 12 mid-marsh replicate quadrats. This method was started in 2012 as a new part of the annual GCE monitoring and supplements the invertebrate data that has been collected since October 2000. This data set includes observations from 2012 to 2023 and will be updated annually to include the prior year observations.

Juvenile Salmonid Emigration Monitoring in the Lower American River, California.

Overview Operation of rotary screw traps on the Lower American River is part of a collaborative effort by the U.S. Fish and Wildlife Service, Pacific States Marine Fisheries Commission, and the California Department of Fish and Wildlife. The primary objectives of the study are to collect data that can be used to estimate the passage of juvenile fall-run Chinook Salmon Oncorhynchus tshawytscha and to quantify the raw catch of steelhead Oncorhynchus mykiss as well as winter, spring, and late fall runs of Chinook Salmon. Secondary objectives of the trapping operations focus on collecting biological data on juvenile salmonids and gathering environmental data that will be used to develop models that correlate environmental parameters with salmonid size, temporal presence, abundance, and production. The data package contains seven datasets including: raw catch, trap operation, environmental, and trap efficiency data. Raw Catch – Chinook Dataset This dataset covers ALL Chinook Salmon captured by the rotary screw traps. This spreadsheet includes biological data on: 1) unmarked fall-, spring-, and winter-run Chinook Salmon 2) marked (adipose clipped OR "fin clip") hatchery origin Chinook Salmon 3) recaptured marked fall-run (BBY OR "Pigment / Dye", Photonic Dye, and VIE OR "Elastomer") Chinook Salmon utilized in trap efficiency trials. Raw Catch – Steelhead Dataset This dataset covers ALL steelhead captured by the rotary screw traps. This spreadsheet includes biological data on: 1) unmarked (natural origin) steelhead 2) marked (adipose clipped OR "fin clip") hatchery origin steelhead 3) recaptured marked steelhead utilized in trap efficiency trials.

USFWS Red Bluff Diversion Dam Rotary Screw Trap Juvenile Fish Monitoring Database

The United States Fish and Wildlife Service (USFWS) has conducted direct monitoring of juvenile Chinook Salmon Oncorhynchus tshawytscha passage at the Red Bluff Diversion Dam (RBDD), river kilometer (RKM) 391 on the Sacramento River, in Northern California since 1994 (Johnson and Martin 1997). Martin et al. (2001) developed quantitative methodologies for indexing juvenile Chinook passage using rotary-screw traps (RST) to assess the impacts of the United States Bureau of Reclamation’s (USBR) RBDD Research Pumping Plant. Absolute abundance (passage and production) estimates were needed to determine the level of impact from the entrainment of salmonids and other fish community populations through RBDD’s experimental ‘fish friendly’ Archimedes and internal helical pumps (Borthwick and Corwin 2001). The original project objectives were met by 2000 and funding of the project was discontinued. From 2001 to 2008, funding was secured through a CALFED Bay-Delta Program grant for annual monitoring operations to determine the effects of restoration activities in the upper Sacramento River aimed primarily at winter Chinook Salmon*. The USBR, the primary proponent of the Central Valley Project (CVP), has funded this project since 2010 due to regulatory requirements contained within the National Marine Fisheries Service’s (NMFS) Biological Opinion for the Long-term Operations of the CVP and State Water Project (NMFS 2009 and 2019). The project began sampling in 1994 with (4) 2.4-m diameter RST’s which sampled through March of 2020. From March 25, 2020 through June 25, 2020, in order to protect employee health and safety during the Coronavirus global pandemic (COVID-19), sampling ceased. Just prior to resuming sampling operations in July of 2020, (4) 1.5-m diameter and one 2.4-m diameter RSTs were re-installed across the transect at the RBDD site. This new five-trap configuration provides a solution to sampling a location that has become shallower since the RBDD gates were permanen

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.

Distribution and habitat use of juvenile steelhead and other fishes of the lower Feather River

Understanding how fish presence is related to habitat features is useful in restoration planning and monitoring as better information about how fish use habitat may lead to more impactful restoration projects. The California Department of Water Resources (DWR), conducted a two-year study of microhabitat and mesohabitat in Feather River. The goal of this study was to identify relationships between habitat conditions (depth, substrate, velocity, and cover) and where juvenile Chinook salmon and steelhead occur. Snorkel surveys were conducted monthly March through August in 2001 and 2002 across 29 different sites, which were selected at random (13 in Low Flow Channel, and 16 in High Flow Channel). Each sampling section covered an area 25 meters long by 4 meters wide, running parallel to riverbank. These data were published to support the Healthy Rivers and Landscapes Science Program.

Juvenile Tree Responses to Soil Warming at Harvard Forest since 1995

The main goal of this study is to assess eastern tree species’ growth, survivorship, and phenological responses to soil warming in order to forecast future changes in forest succession and carbon dynamics. From 2003 through 2010, we determined that shade-tolerant, normally slower-growing species benefitted most from warming. We are continuing to study species-species responses to investigate the duration of and mechanisms behind species- and functional group responses to climate warming. Monitoring long-term demographic and physiological responses of juvenile trees with and without soil warming will allow us to model future eastern tree species successional shifts under warmer climate conditions.

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.

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.

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.

Endurance swimming performance and physiology of juvenile Green Sturgeon (Acipenser medirostris) at different temperatures, CA, 2022

This dataset provides information on the endurance swimming performance and physiological responses of juvenile Green Sturgeon (Acipenser medirostris), reared and tested at the University of California, Davis, in 2022. Fish were acclimated to two temperature treatments (13°C and 18°C) for 14 days prior to swimming trials. Endurance tests were conducted at 47–53 days post-hatch (DPH) in modified swim tunnels at fixed water velocities (25–55 cm s⁻¹) to measure time-to-fatigue (End.min), station-holding behavior (Station_holding), and swimming type (Swim.type). Fish morphometrics (e.g., weight, fork length, total length) were recorded before trials. Post-swim physiological analyses included whole-body measurements of cortisol, glucose, lactate, and protein. Tissue homogenates were processed to determine concentrations normalized to fish weight (e.g., Cortisol_ng_g, Glucose_ug_g, Lactate_ug_g). Standard curves showed high assay linearity (R² > 0.98) and low variability (CV < 10%). This dataset contributes to understanding sturgeon endurance and physiological stress under different environmental conditions, providing insights into their resilience to temperature and flow changes relevant to river management and conservation efforts. Variables include: species, developmental stage (DPH), rearing and trial conditions (tank, temperature, velocity), fish morphometrics (weight, fork length, total length), and physiological metrics (cortisol, protein, glucose, and lactate).

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
