Blended Scenario Overview

This page gives descriptions and model inputs of all the R2R blended scenarios

Scenario	Description	Model inputs
Baseline	The “baseline scenario” represents the status quo and current management.	Flow data - 2019 CalSim BiOp Temperature data - modeled consistent with 2019 CalSim BiOp Habitat data - existing SIT DSM habitat + planned restoration projects. The methodology for incorporating restoration projects to current SIT habitat data can be here.
Kitchen Sink	Recovery scenario that includes habitat, hydrology, harvest, and hatchery management actions.	Habitat Theoretical Maximum habitat inputs Food Subsidies Predation Reduction Hydrology Functional Flows (FF) in all years Harvest Harvest only hatchery fish (ocean/commercial) all years Intelligent CRR harvest (in-river/tribal, recreational) all years Hatcheries Terminal hatchery/ocean outplanting (current release output number) all years
Dry Year Focus	Recovery scenario that focuses on management actions in dry years.	Habitat Floodplain Habitat (rice fields) - dry years Food Subsidies - dry years Hydrology Ecological Functional Flows (EFF) - dry years Harvest No harvest of dry year cohorts (ocean/commercial, tribal, recreational) Harvest only hatchery fish (ocean/commercial, tribal, recreational) all years Hatcheries Terminal hatchery/ocean outplanting (current release output number) all years
Habitat and Hatcheries Focus	Recovery scenario that focuses on habitat, hatchery, and harvest actions.	Habitat Theoretical Maximum habitat inputs - all years Food Subsidies - all years Predation Reduction - all years Hydrology Current Operations Harvest Intelligent habitat harvest (ocean/commercial, in-river/tribal, recreational) - all years Hatcheries Terminal hatchery/ocean outplanting (current release output number) all years
