SACRAMENTO, CALIF. — The Bureau of Reclamation’s Mid-Pacific Region and the California Department of Water Resources have made Central Valley water management planning software, CalLite 2.0, available for public use. CalLite 2.0 can be used to simulate the hydrology of California’s Central Valley, reservoir and project operations, delivery allocation decisions, delta salinity responses to river flow and export changes, and habitat-ecosystem flow indices.

The model, which is designed to support studies of the federal Central Valley Project and the State Water Project, can be applied to assist in the screening of a variety water management options and to educate decision makers on system responses. The tool is designed for use in a variety of stakeholder processes for improved understanding of water system operations and future management changes.
