<br />WATER SUPPLY ASSESSMENT FEBRUARY 13, 2023
<br />23
<br />(October 2019). The projected regional demand is adjusted to account for water conserved by
<br />best management practices from active, code-based, and price-effect conservation.
<br />Supply analysis includes Colorado River supplies, SWP supplies, and existing proposed storage
<br />programs through Metropolitan’s service area. Colorado River Aqueduct (CRA) supplies include
<br />supplies that would result from existing and committed programs and from implementation of
<br />the Quantification Settlement Agreement (QSA) and related agreements. State Water Project
<br />(SWP) supplies are estimated using the 2019 SWP Delivery Capability Report distributed by the
<br />California Department of Water Resources (DWR) in August 2020. Regarding storage,
<br />Metropolitan assumed the current (2020) storage levels at the start of simulation and used the
<br />median storage levels going into each of the five-year increments based on the balances of
<br />supplies and demands. See Table 7 below showing Metropolitan’s ability to meet growing
<br />demands in normal, single-dry, and multiple-dry year climate scenarios.
