title: Data for "Juvenile Pacific salmonid habitat use in two Puget Sound lowland rivers"

description: This dataset represents habitat measurements (Habitat_data_2023_04_25.csv) and fish sampling (Fish_data_2023_04_25.csv) from the Snoqualmie and Green rivers in the Puget Sound region of Washington State, USA. Using a cataraft mounted with a boat electrofisher, these data were collected between late winter and late spring from 2016 through 2022. Measurements were of 25-m-long transects along six different edge habitat types in the two rivers. The edge habitats represented in this dataset are ‘armored banks’, ‘biorevetment banks’, ‘unarmored banks’, ‘bars’, ‘backwaters’, and ‘side channels’. These data were collected as part of monitoring of eight habitat restoration or bioengineered bank stabilization projects in the Snoqualmie and Green rivers, along with three more general studies of fish-habitat relationships in the two rivers. These data are analyzed and presented in the journal article “Juvenile Pacific salmonid habitat use in two Puget Sound lowland Rivers”, published in the Transactions of the American Fisheries Society (https://afspubs.onlinelibrary.wiley.com/doi/10.1002/tafs.10457). All data were collected by the King County Water and Land Resources Division, Science and Technical Support Section.Habitat data were collected during the day and include measurements of the width of low-velocity habitat (≤ 0.45m/s) and water depth along each transect. Fish sampling occurred after darkness fell the evening following habitat data collection. Fish data include the number of each species sampled at each transect and the number of seconds each transect was electrofished.

For Green River sampling events, flows are from the Green River near Auburn USGS gage (#12113000). For Snoqualmie River sampling events, flows are from the Snoqualmie River near Carnation USGS gage (#12149000).Event_notes (text) – Notes about individual sampling events.Transect_ID (integer) – A unique numeric identifier for each sampled transect. This identifier can be used to join the habitat dataset with the fish dataset.Unit_ID (text) – An additional identifier for each sampled transect. This identifier is not unique across sampling events and may or may not be unique within a sampling event.Edge_type (text) – The edge habitat type sampled. Either ‘armored bank’, ‘biorevetment bank’, ‘unarmored bank’, ‘bar’, ‘backwater’, or ‘side channel’.Transect_type (text) – Classification of transects as either ‘control’, ‘reference’, or ‘treatment’ for sampling of habitat restoration and bioengineered bank protection projects.Transect_notes (text) – Notes about sampling of individual transects.Time_surveyed (integer) – The number of seconds that a transect was electrofished.Species (text) – Three letter codes representing the fishes caught at each transect. A blank cell indicates that no fish were caught in that transect. Species codes: BBH = brown bullhead catfish (Ameiurus nebulosus); BCP = black crappie (Pomoxis nigromaculatus); BGS = bluegill sunfish (Lepomis macrochirus); CHK = chinook salmon (Oncorhynchus tshawytscha); CHM = chum salmon (Oncorhynchus keta); COH = coho salmon (Oncorhynchus kisutch); COT = cottids (Cottus sp); CUT = coastal cutthroat trout (Oncorhynchus clarkii clarkii); DAC = unknown dace (Rhinichthys sp); GSF = green sunfish (Lepomis cyanellus); LMB = largemouth bass (Micropterus salmoides); LMP = unknown lamprey; LND = long nose dace (Rhinichthys cataractae); LSS = large scale sucker (Catostomus macrocheilus); MIN = unknown minnow (Cyprinid); MWF = mountain whitefish (Prosopium williamsoni); NPM = northern pike minnow (Ptychocheilus oregonensis); PIN = pink salmon (Oncorhynchus gorbuscha); PMM = peamouth minnow (Mylocheilus caurinus); PSS = pumpkinseed sunfish (Lepomis gibbosus); RBT = rainbow trout (Oncorhynchus mykiss); RKB = rock bass (Ambloplites rupestris); RSS = redside shiner (Richardsonius balteatus); SPD = speckled dace (Rhinichthys osculus); STH = steelhead (Oncorhynchus mykiss); SUN = unknown sunfish (Lepomis sp); TRT = unknown trout; TSB = three-spine stickleback (Gasterosteus aculeatus); YLP = yellow perch (Perca flavescens).Age (text) – The estimated age classification for salmonids. 0+ = sub-yearling juvenile; 1+ = yearling or older juvenile.Hatchery_mark (text) – Whether or not salmonids had marks or fin clips indicative of hatchery origin.Number (integer) – The number of fish observed. 1 if a fish was measured or &gt; 1 if the number represents a sum of multiple fish that were counted and not individually measured. A blank cell indicates that no fish were caught in that transect.Length (integer) – The fork length or total length of a sampled fish.Fish_notes (text) – Notes regarding individual sampled fish.<br>The “Habitat_data_2023_04_25.csv” comma separated value file contains the following fields:Project (text) – The name of the project or sampling effort.River (text) – The name of the river where the sampling took place (Snoqualmie or Green).Date (date) – The date sampling took place (mm/dd/yyyy).Event_notes (text) – Notes about individual sampling events.Transect_ID (integer) – A unique numeric identifier for each sampled transect.
