- A water supply assessment, which projects how much water will be available in the state over the next 50 years

- A water demand forecast, which projects how much water will be needed in the state over the next 50 years

- A gap analysis, which identifies the difference between the water supply and the water demand

- A strategy to close the gap, which includes a mix of conservation measures, water reuse projects, and new water sources
