Format

dataframe with 30 rows and 11 variables:

flow_cfs

integer flow value in cubic feet per second

FR_spawn_WUA

fall run spawning WUA in square feet per 1000 feet

LFR_spawn_WUA

late-fall run fry spawning WUA in square feet per 1000 feet

ST_spawn_WUA

steelhead spawning WUA in square feet per 1000 feet

watershed

name of watershed

Central Valley Floodplain Evaluation and Delineation (CVFED) HEC-RAS hydraulic model refined for use in the NOAA-NMFS Winter Run Chinook Salmon life cycle model

Details

The spawning WUA were derived from a FWS River2D model. The study is broken into several segments: Keswick to A.C.I.D. (3.5 mi), A.C.I.D. to Cow Creek (18.5 mi), Cow Creek to Battle Creek (8.5 mi), Battle Creek to Red Bluff (22.5 mi), and Red Bluff to Deer Creek (23.5 mi). The Upper Sacramento fall run spawning WUA values include the spawning that occurs in the Upper and Upper-mid Sacramento River (Keswick to Deer Creek). The Late-Fall Run, Winter Run, and Steelhead spawn from Keswick to Battle Creek. The A.C.I.D. boards are in April 1st - October 31st
