Observations and summaries of juvenile coho salmon abundance and survival, stream surveys, and habitat surveys, East Fork Lewis River, Southwest Washington, 2017
This folder contains data in three parts. The juvenile coho salmon abundance and survival data consists of fish survey data and the associated analysis, including documentation of the analysis code, methods, and protocols used. Habitat survey data consists of both reach-level (~100 meter sections) and continuous (watershed scale) surveys. The summaries item and its contents include summaries produced from fish and habitat surveys conducted in Mason Creek, tributary of the East Fork Lewis River, SW Washington, during summer of 2017.
Habitat stream survey data collected in Mason Creek, tributary of East Fork Lewis River, SW Washington, during summer of 2017
The protocol for the habitat surveys are outlined in the file entitled "Fish Rescue Field Protocol_2017_FINAL VERSION_2017-06-01.pdf". The habitat dataset is stored in an Access database entitled "FishRescue_HabitatData_2017.accdb" and consists of both reach-level (~100 meter sections) and continuous (watershed scale) surveys.
Stream habitat characteristics, energy development metrics, and fish catch per unit effort data for 91 sites (100m stream reach) sampled in the summers of 2012 and 2013.We sampled four streams in the Dry Piney Drainage (Dry Piney, Beaver Dam, Black Canyon, and North Black Canyon), five in the Fogarty Drainage (North and South Fogarty, North and South Pine Grove, and Sawmill) and four in the South Beaver Drainage (North Beaver, South Beaver, Middle Beaver, and Spring).
Summary drainage basin and low-flow characteristics in gaged Hawaii streams and summary rainfall projections for the late 21st century and associated changes in low flows and usable habitat for native stream fauna in gaged and ungaged Maui, HI streams
The spreadsheets associated with this metadata file represent: (Tab 1) Streamflow and drainage basin characteristics of selected gaged steams in Hawaii used to develop statistical models to estimate surface-water availability during low flow conditions and for varying rainfall conditions. For gaged streams on Maui, two sets of projected rainfall conditions for the late 21st century and associated estimates of changes in low flows and usable habitat for native stream fauna are also provided. (Tab 2) Drainage basin characteristics of ungaged streams on Maui used to apply the statistical models, two sets of projected rainfall conditions for the late 21st century, and associated estimates of changes in low flows and...
Comprehensive map of regionally-important aquatic networks for the Rensselaer Plateau. Aquatic networks represent long, hydrologically-connected two-dimensional landscape-level areas with a centralized stream system plus closely associated buffer areas that most strongly influence the ecology of that system.
Human impacts occurring throughout the DOI Northeast Climate Science Center, including urbanization, agriculture, and dams, have multiple effects on streams in the region which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results of a current condition assessment of stream habitats based on fish response to human land use, water quality impairment,...
Stream habitat characteristics and relative abundances of the Yellowcheek Darter (Nothonotus moorei) at select riffle sites among the four headwater forks of the Little Red River in Arkansas
The Yellowcheek darter (YCD), Nothonotus moorei (Robison and Buchanan 2020), is endemic to the headwater tributaries (a.k.a. ‘forks’) of Little Red River system (South Fork, SF; Middle Fork, MF; Archey Fork, AF; and Beech Fork, BF) in north central Arkansas. Large portions of critical stream habitat in each stream fork were inundated in 1964 with the construction of Greers Ferry Dam, and the YCD is now restricted to relatively short, free-flowing stretches of each fork upstream of the dam. YCD were once reported as the most abundant riffle species in these headwater tributaries (Robison and Harp 1981), however, multiple status surveys and collection efforts in the decades since dam construction have documented a...
Summaries of fish and habitat surveys for juvenile coho salmon in Mason Creek, tributary of the East Fork Lewis River, SW Washington, during summer of 2017
This folder and its contents include summaries produced from fish and habitat surveys conducted in Mason Creek, tributary of the East Fork Lewis River, SW Washington, during summer of 2017. First, estimates of abundance and survival for juvenile coho salmon were generated for three time periods (early, middle, and late) during the summer of 2017 and reported in the file "Estimates of juvenile coho summer abundance and survival_MasonCreek_2017.xlsx". Second, summaries of the continuous habitat surveys can be found in the file "FinalStats_MasonMill2017_FishRescue.xlsx". Specifically here, the total length of stream habitat by habitat type (flowing, fragmented, dry) and the frequency and area of stream pools are summarized...
