Proven Track Record
CRAFT is now live and delivering impressive results. Prior to launch, an eight-year hindcast demonstrated strong performance across 18 reservoirs, including 100% accuracy for Lake Shasta every year since 2018.
CRAFT changed how we plan. We can move in November, not wait for March.
