Abstract California faces cycles of drought and flooding that are projected to intensify, but these extremes may impact water users across the state differently due region's natural hydroclimate variability complex institutional framework governing deliveries. To assess risks, this study introduces a novel exploratory modeling informed by paleo climate‐change based scenarios better understand how impacts propagate through Central Valley's system. A stochastic weather generator, conditioned on tree‐ring data, produces large ensemble daily sequences flood conditions under Late Renaissance Megadrought period (1550–1580 CE). Regional climate changes applied data drive hydrologic projections for Sacramento, San Joaquin, Tulare Basins. The resulting streamflow ensembles used in an stress test using Food‐Energy‐Water System model, highly resolved, model storage conveyance throughout California's Valley. Results show megadrought lead unprecedented reductions inflows at major reservoirs. Both junior senior rights holders experience multi‐year periods curtailed deliveries complete drawdowns groundwater assets. When dynamics combined with change, risks depletion reservoir sustained curtailment multiple years increase. Asymmetries risk emerge depending source, rights, access banks.
