Bradley Lake inflow computed from NWS APRFC CHPS forecast and water balance model that accounts for inputs from major tributaries BRUA2 and Upper Battle Creek diversion, and precipitation.

The National Weather Service prepares its forecasts and other services in collaboration with agencies like the US Geological Survey, US Bureau of Reclamation, US Army Corps of Engineers, Natural Resource Conservation Service, National Park Service, ALERT Users Group, Bureau of Indian Affairs, and many state and local emergency managers across the country.
