This is an ongoing Bonneville Power Administration funded project to annually collect, PIT tag, and release wild Chinook salmon parr in up to 15 streams of the Salmon River drainage in Idaho and subsequently monitor these fish through in-stream monitoring sites and downstream dams. The overall study objectives are to assess the migrational characteristics and estimate parr-to-smolt survival for Snake River wild spring/summer Chinook salmon smolts at Lower Granite Dam, characterize parr and smolt survival and movement out of natal rearing areas of selected streams and examine the relationships between fish movement, environmental conditions within the streams, and weather and climate data. This project also collects parr-to-smolt growth information on previously PIT-tagged wild Chinook salmon parr at the Lower Granite Dam sort-by-code PIT detection system each spring. A goal of this study is to characterize run-timing of wild fish to determine if consistent patterns are apparent and to provide daily information for real-time management decisions during the smolt out-migrations. Up to 6 water quality parameters collected hourly in 16 streams of the Salmon River basin in Idaho.

Adult salmonid data collected from various areas within the Klamath basin watershed. Various tributaries are monitored using video systems (Bogus Creek, Shasta River, Scott River), other areas are monitored using redd/carcass surveys, and Iron gate Hatchery adult returns. The main purpose of the data is to estimate escapement of fall Chinook slamon, although data on other species (steelhead, coho salmon) also collected. For more information on the various collection methods, please view the specific metadata document included with the data download. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000381.

The BCPITTAGS database is used to store data from an Oncorhynchus mykiss (steelhead/rainbow trout) population dynamics study in Big Creek, a coastal stream along the Big Sur coast in Monterey County, California. The Landscape Ecology team at the Fisheries Ecology Division in Santa Cruz, CA is investigating the life history of this relatively small O. mykiss population to determine its significance in the persistence of the larger South-Central California Coast Steelhead Distinct Population Segment (DPS), which includes anadromous O. mykiss populations from the Pajaro River up to (but not including) the Santa Maria River, to see how these small coastal streams with little human-related impacts may contribute to DPS viability and resiliency. The database stores data from mark-recapture surveys, fish movement data collected via instream PIT tag readers, and stream environmental data. The data will be assimilated into a stage-structured population model, where stages include life history stage and location. Movement and survival rates will be determined and analyzed using data from the stationary PIT tag readers and mobile tracking devices.

This data release includes 3 child items with tracking data for caribou, a terrestrial mammal that inhabits Alaska and Canada. Child Item 1: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Denali Herd, Alaska, 2010-2018" Child Item 2: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999" Child Item 3: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Nelchina Herd, Alaska, 1999-2002"

This data release includes 2 child items with tracking data for Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. Child Item 1: "Argos Satellite Tracking Data for Yellow-billed Loons (Gavia adamsii) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Yellow-billed Loons (Gavia adamsii) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

These data were compiled to test hypotheses regarding drivers of movement of brown trout. Objectives of our study were to test whether the degree of movement varied in response to placement of a weir in Bright Angel Creek, fall timed flooding events, or simply seasonal changes. These data represent summarized capture histories of brown trout in terms of states based on physical locations, data on removal efforts in Bright Angel Creek, and summaries of effort in the mainstem Colorado River. These data were collected at several locations along the Colorado River in Glen and Grand Canyon, including Bright Angel Creek from 2011 to 2018. These data were collected by U.S. Geological Survey, National Park Service, and Arizona Game and Fish. These data can be used to test hypotheses regarding drivers of brown trout movement in the Colorado River in its Grand Canyon segment.
