Delta STARS Shiny app
The Delta STARS (S
ravel Time, a
imulation) Model is an individual-based simulation model that predicts survival, travel time, and routing of juvenile salmon migrating through the Sacramento-San Joaquin River Delta. The model's structure and parameters are based on a recent analysis (Perry et al. 2018
) that relates individual survival, travel time, and routing of late-fall Chinook salmon to daily Sacramento River flows at Freeport
and Delta Cross Channel operations
. Delta STARS developed by USGS Quantitative Fisheries Ecology Section; deployed by SacPAS.
Loss and Salvage Predictor Realtime forecast of Loss and Salvage is made from approximately December to mid-June
Predicts loss and/or salvage of endangered steelhead and winter run Chinook salmon at the CVP and SWP pumping facilities at the southern end of the Sacramento-San Joaquin Delta. Model developed by Tillotson et al. 2022
Egg Growth Model Spawning to Emergence
The salmon egg growth modeling process begins with egg deposition at the time of spawning. Development rate and survival can be modeled by various methods to determine fry emergence from the gravel. This tool allows the user to control temperature inputs, redd/carcass/adult counts and survival details for egg development modeling.
Shinyapps developed by SacPAS in support of various tools and models.
