Datasets used to calculate spawning, instream, and floodplain rearing habitat areas for Chinook Salmon and Steelhead

Instream ({watershedname}_instream)

Datasets containing the Weighted Usable Area (WUA) in square feet per 1000 feet as a function of flow in cubic feet per second for Fall Run (FR), Spring Run (SR), Winter Run (WR), and Steelhead (ST) depending on species occurance and modeling availability.

Typical data structure for streams:

  • flow_cfs - flow value in cubic feet per second

  • FR_spawn_wua - Spawning WUA in square feet per 1000 feet

  • FR_fry_wua - Fry (up to 50 mm) WUA in square feet per 1000 feet

  • FR_juv_wua - Juvenile WUA in square feet per 1000 feet

  • watershed - Name of watershed

Floodplain ({watershedname}_floodplain)

Datasets containing the total inuncated area in acres as a function of flow in cubic feet per second for Fall Run (FR), Spring Run (SR), Winter Run (WR), and Steelhead (ST) depending on species occurance and modeling availability.

Typical data structure for streams:

  • flow_cfs - Flow value in cubic feet per second

  • FR_floodplain_acres - Total inundated area in acres for Fall Run

  • SR_floodplain_acres - Total inundated area in acres for Spring Run

  • ST_floodplain_acres - Total inundated area in acres for Steelhead

  • watershed - Name of watershed
