F-CO on the San Joaquin River System
Forecast-Informed Operations (F-IO)
12
Forecast-Informed Operations (F-IO) is a program to optimize water and flood operations reservoirs
F-IO benefits:
Will reduce flood risk downstream of the reservoirs
Can provide water supply enhancement
13
To implement F-IO:
Improved seasonal reservoir inflow forecasts
Dynamic/variable reservoir flood control diagram (FCD) that allows pre-releases
Development and use of ensembles in forecasting
Detailed engineering analysis to understand & document the potential benefits and feasibility of F-IO
CEQA and NEPA compliance
Approval of USACE and Congress to change the FCD

Partnership between DWR/USACE/CNRFC invaluable for F-CO
F-CO is a cost effective way to improve flood protection
F-IO requires willing participation from reservoir operators
Any changes to the provision in the water control manuals, whether to improve flood control, water supply, or other purposes, must be enacted by Congress.
