<br /> 2. California Aqueduct includes Central Valley transfers and storage program supplies conveyed by the aqueduct.
<br /> 3. Colorado River Aqueduct includes programs and Exchange with SDCWA conveyed by the aqueduct-

<br /> 5. Total demands are adjusted to include Exchange with SDCWA.
<br /> 6.2.6.2 MET's Drought Risk Assessment Results
<br /> For its Drought Risk Assessment (DRA), MET assessed the reliability of each individual water supply source
<br /> over the five-consecutive-year drought through a modeling method using the same historical hydrologic
<br /> conditions as the water service reliability assessment: 1922 to 2021. MET used the five consecutive years
<br /> of 1988 to 1992 to complete its DRA, because this represents the driest five-consecutive year historical
<br /> sequence for MET's supply. The results indicate that MET's SWP and CRA supplies alone cannot meet
<br /> demands during this five-year drought period without additional actions. MET's 2025 UWMP therefore
