• GSA’s shall utilize information provided, as available, by the Department…or other data of comparable quality, to develop the water budget:

• Historical water budget information: • Mean annual temperature • Mean annual precipitation • Water year type • Land use.

• Current water budget information: • Temperature • Water year type • Evapotranspiration • Land use.

• Projected water budget information: • Population • Population growth • Climate change • Sea level rise.

• The Department shall provide the California Central Valley Groundwater-Surface Water Simulation Model (C2VSIM) and the Integrated Water Flow Model (IWFM) for use by Agencies in developing the water budget.
