Endangered Species Project
Lead
California Department of Pesticide Regulation [DPR]
Description
In California, DPR has been studying endangered species protection issues with federal funding since 1988. DPR activities include mapping sites occupied by federally listed species, evaluating pesticide exposure risks to inhabited sites, classifying risk and developing protection strategies to minimize risk as needed. There are currently 359 federally listed species in California including federally protected endangered and threatened species, proposed endangered, proposed threatened and Category 1 candidate species (that await only administrative processes to become protected species). Collectively, the federally listed species may occupy about 16 million acres, or about 16 percent of the land area of the state, albeit at very low densities. Of all federally listed species in California, the San Joaquin kit fox has by far the greatest overlap with agricultural areas, accounting for about 10 million acres in 14 counties, mostly in the agriculturally rich southern San Joaquin Valley. Other species that are interspersed with agricultural areas include birds, mammals, reptiles, amphibians, crustaceans and many plants.

Description
The Passage Assessment Database (PAD) is an ongoing map-based inventory of known and potential barriers to anadromous fish in California, compiled and maintained through a cooperative interagency agreement. The PAD compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. The database is set up to capture basic information about each potential barrier. It is designed to be flexible. As the database grows, other modules may be added to increase data detail and complexity.

Telemetered Stream Gauge Stations [Surface Water Monitoring]
Lead
U.S. Bureau of Reclamation [USBR]
Description
A network of stream gauges record and telemeter river stage information. Flow measurements by field crews help calibrate and confirm calculations. Data from stream gage telemetry requires careful consideration as field conditions and equipment malfunctions can provide erroneous readings. A more accurate assessment of actual flow rates requires a review of the flow record and processing to account for actual conditions.

Description
The Smelt Larva Survey provides near real-time distribution data for longfin smelt larvae in the Delta, Suisun Bay and Suisun Marsh. Sampling takes place within the first two weeks in January and repeats every other week through the second week in March. Each 4-day survey consists of a single 10-minute oblique tow conducted at each of the 35 survey locations (see map) using an egg and larva net. The 505-micron mesh net is hung on a rigid frame shaped like an inverted-U, which in turn is attached to skis to prevent it from digging into the bottom when deployed. The net mouth area measures 0.37 m2. The conical net tapers back from the frame 3.35 m to a 1-liter cod-end jar, which collects and concentrates the sample. Immediately after each tow, juvenile fishes are removed, identified, measured and returned to the water immediately, and the remaining larvae are preserved in 10% formalin for later identification in the Lab in Stockton.

Spring Kodiak Trawl Survey
Lead
California Department of Fish and Wildlife [CDFW]
Description
The Spring Kodiak Trawl Survey (SKT) has sampled annually since its inception in 2002. The SKT determines the relative abundance and distribution of spawning delta smelt (Hypomesus transpacificus). The SKT samples 40 stations each month from January to May. These 40 stations range from San Pablo Bay upstream to Stockton on the San Joaquin River, Walnut Grove on the Sacramento River, and the Sacramento Deep Water Ship Channel. Each 'Delta-wide' survey takes approximately 4 - 5 days per month to complete. Historically, 'Delta-wide' surveys were followed by a 'Supplemental' survey two weeks later to intensively sample areas of highest delta smelt concentration to estimate the proportion of male and female delta smelt that were in pre-spawning, spawning and spent maturation stages. Beginning in 2008, in an effort to minimize take of spawning adults, routine 'Supplemental' surveys were discontinued and are now only conducted under the recommendation of the Smelt Working Group and the approval of managers.

Breeding Waterfowl Surveys
Lead
Pacific Flyway Council
Description
The California breeding population survey is modeled after the continental breeding survey. Though most of the wintering waterfowl in California breed outside of the state, California still has a significant number that both breed and winter here. CDFW and California Waterfowl Association (CWA) biologists conduct the California survey. Surveyed areas include wetland and agricultural areas in northeastern California, throughout the Central Valley, the Suisun Marsh, and some coastal valleys. CDFW biologists and warden-pilots use a fixed-wing aircraft to fly all of the transects while CWA completes the "ground" portion of the survey using a helicopter. This survey also utilizes a visibility correction factor. For the most part, ducks that only winter in California comprise most of the harvest, but CDFW augments the continental survey assessment with the estimates of California's breeding population for developing hunting regulation recommendations.

Yolo Bypass Fish Monitoring
Lead
California Department of Water Resource [DWR]
Description
California Department of Water Resources (DWR) has operated a fisheries monitoring program in the Yolo Bypass, a seasonal floodplain and tidal slough, since 1998. The objectives of the Yolo Bypass Fish Monitoring Program (YBFMP) are to: (1) collect baseline data on lower trophic levels (phytoplankton, zooplankton, and aquatic insects), juvenile fish and adult fish, hydrology, and water quality parameters;(2) investigation of the temporal and seasonal patterns in chlorophyll-a concentrations, including whether high concentrations are exported from the Bypass during agricultural and natural flow events and the possibility of manipulating bypass flows to benefit listed species like Delta Smelt (Hypomesus transpacificus) and Chinook salmon (Oncorhynchus tshawytscha). The YBFMP operates a rotary screw trap and fyke trap, and conducts biweekly beach seine and lower trophic surveys in addition to maintaining water quality instrumentation in the bypass. The YBFMP serves to fill information gaps regarding environmental conditions in the bypass that trigger migrations and enhanced survival and growth of native fishes, as well as provide data for IEP synthesis efforts.

Continuous Monitoring of Water Quality & Suspended-Sediment Transport [Bay-Delta]
Lead
U.S. Geological Survey [USGS]
Description
Our group at the USGS continuously monitors suspended-sediment concentration (SSC), turbidity, dissolved oxygen, temperature, salinity, and water level at many sites throughout the San Francisco Bay (Bay) and the Sacramento-San Joaquin Rivers Delta (Delta). Our work began in 1988 to explore the spatial and temporal variability of water quality and sediment transport and to provide decision makers, resource managers, and the public with the most up-to-date knowledge. Topics we study include water quality, sediment transport, water clarity, erosion and deposition, sediment-associated contaminants and habitat quality, wetland restoration, and sea level rise.

National Water Use Science Project [NWUSP]
Lead
U.S. Geological Survey [USGS]
Description
The USGS National Water Use Science Project (NWUSP), a component of the Water Availability and Use Science Program (WAUSP), facilitates the 5-year compilation of water use estimates for the United States as part of the National Water Census (NWC). The NWC, implemented as part of the SECURE (Science and Engineering to Comprehensively Understand and Responsibly Enhance) Water Act (Subtitle F of Public Law 111-11, the Omnibus Public Land Management Act), provides data and tools designed to support water managers in the accurate assessment of water availability at regional and national scales (https://water.usgs.gov/ watercensus/). Water managers across the United States require more complete, timely, and accurate water-availability information to support policy and decision-making, specifically, data associated with water withdrawals and consumptive use. Recognizing the limitations of current water-use data, the SECURE Water Act authorized a program that supports activities related to data collection and methods research and development at the State level. The USGS Water-Use Data and Research program (WUDR) will provide financial assistance through cooperative agreements with State water resource agencies to improve the availability, quality, compatibility, and delivery of water-use data that is collected or estimated by States. The Act requires that these State water use and availability datasets be integrated with appropriate datasets that are developed and/or maintained by the USGS.

Central Valley Joint Venture [CVJV]
Lead
U.S. Fish and Wildlife Service [USFWS]
Description
The Central Valley Joint Venture (CVJV) is a self-directed coalition consisting of 21 State and Federal agencies, private conservation organizations and one corporation. This partnership directs their efforts toward the common goal of providing for the habitat needs of migrating and resident birds in the Central Valley of California. The CVJV was established in 1988 as a regional partnership focused on the conservation of waterfowl and wetlands under the North American Waterfowl Management Plan. It has since broadened its focus to the conservation of habitats for other birds, consistent with major national and international bird conservation plans and the North American Bird Conservation Initiative. The Central Valley Habitat Joint Venture was formally organized in 1988 and was one of the original six priority joint ventures formed under the NAWMP. Renamed the Central Valley Joint Venture in 2004, the Management Board now consists of nineteen public and private members. The CVJV is currently administered through a coordination office within the U.S. Fish and Wildlife Service, and is guided by a Management Board that receives input and recommendations from a variety of working committees.

SAIL [Coordinated Enhanced Acoustic Telemetry Program]
Lead
U.S. Bureau of Reclamation [USBR]
Description
These monitoring efforts can provide critical information on juvenile salmonid distribution and survival, which inform biologists and managers interpretations of the exposure and intensity of CVP and SWP water operation risks on tagged populations in Central Valley rivers and the Bay- Delta. Understanding salmon survival and migration dynamics in the Delta and its tributaries is critical to the recovery of ESA-listed species, and sport and commercial fisheries management. For example, estimating the population size of endangered Sacramento River Winter-run Chinook (SRWRC) as they enter and exit the Delta is considered critical for informing Delta water management actions (Interagency Ecological Program (IEP) SAG 2013). “The use of realtime acoustic receivers that immediately transmit acoustic tagged (AT) fish detections needs to be included in the expanded network” (Johnson et al., in press). Tracking the fate of individual tagged fish will be accomplished with AT and used to develop estimates of survival and movement for other non-AT fish also part of that group. Population level sampling programs will use survival estimates generated by AT and applied to other mass marked (coded wire tagging) groups to develop improved capture efficiency for these sampling programs. Objectives: • Deploy and service field monitoring acoustic telemetry stations at locations important to fish and water management. • Implant, transport, and release acoustically tagged juvenile ESA-listed wild and hatchery juvenile salmonids. • Analysis and synthesis to support production and development of new metrics for understanding the survival, distribution, and entrainment of juvenile salmonid along the Sacramento River and its floodways, as well as, the Bay-Delta. Six-Year Steelhead Study Continuation Reclamation’s Proposed Action for ROC on LTO Section 4.10.5.12.3 Additional Measures includes a San Joaquin Basin Steelhead Telemetry Study -- Continuation of the 6-Year Steelhead telemetry study for the migration and survival of San Joaquin Origin Central Valley Steelhead. This investigation involves undertaking experiments utilizing acoustically-tagged salmonids to confirm proportional causes of mortality due to flows, exports, and other project and non-project adverse effects on steelhead smelt out-migrating from the San Joaquin Basin and through the southern Delta. This study is to coincide with different periods of operations and focus on clipped hatchery steelhead (Oncorhynchus mykiss). The period of interest is between February 15 and June 15, which coincides with a majority of O. mykiss outmigration from the Stanislaus River and recoveries of steelhead smolts in the Mossdale fish monitoring efforts. This period is to include changes in CVP/SWP operations that include reductions in exports, reductions in reverse flows in Old and Middle rivers (OMR), and San Joaquin River pulse flows to assess the influence of flow and exports on juvenile steelhead survival. This study is designed to evaluate juvenile steelhead route selection at channel divergences in the south Delta and along the mainstem San Joaquin River, and how these behaviors influence survival in specific reaches and through the Delta to Chipps Island.

Standard Operating Procedure for Diagnosing and Addressing Predator Detections in Salmon Telemetry Data
Lead
University of Washington [UW]
Description
Tag predation is a complicating factor in juvenile salmon telemetry studies that can bias results, delay timely reporting, and prevent effective data synthesis. This project addresses the problem by (1) characterizing predatory fish movement patterns from existing telemetry data in the Delta; (2) developing a standard operating procedure for diagnosing and handling detections of predated tags in salmon telemetry studies; and (3) implementing the recommendations in a software package in Program R that includes code, a “library” of expected predator behaviors, and example vignettes. The R package will be freely available for download at www.cbr.washington.edu.

White Sturgeon Telemetry Synthesis
Lead
Cramer Fish Sciences
Description
Acoustic telemetry studies are expensive and logistically demanding. A new study to tag and monitor 315 White Sturgeon would require a massive field effort by a large team, but by pooling and leveraging existing datasets, this sample size and analysis will be achieved at a fraction of the cost and effort. In recognition of the efficiencies gained by this approach, the Delta Stewardship Council’s Science Program lists the synthesis and analysis of existing telemetry datasets in Science Action Area (SAA) 2. This project directly addresses SAA 2 by capitalizing on existing White Sturgeon telemetry data through the synthesis of three existing large telemetry dataset to understand system-wide White Sturgeon movements. This contract will synthesize existing long-term acoustic telemetry datasets in order to address high priority research questions for the management of White Sturgeon in the San Francisco Estuary system. These questions include: 1. What is the periodicity of spawning migrations by tagged White Sturgeon, and how do these estimates compare to those from previous, single-basin studies? 2. What is the scope and variability of inter-basin movements exhibited by tagged adult White Sturgeon across years? 3. Is there individual fidelity to specific migration routes or sites within each river basin? 4. Do White Sturgeon migrating through the Yolo Bypass experience delays in reaching spawning grounds relative to fish using the mainstem Sacramento River or San Joaquin River routes? 5. Is the onset of upstream migration movement by individuals associated with a characteristic flow rate or event? This contract will serve as a model for future telemetry synthesis studies by adhering to best practices in scientific computing for reproducible, transparent research, and by making all parts of the data and analysis accessible to the broader Delta research community.
