water shortage mitigation plan phases

Phase I: Drought Alert (Moderate) — Mild indication that shortage conditions may be impending.

Phase II: Drought Warning (Severe) — Drier-than-normal conditions are present and will create a surface water shortage if dry conditions persist.

Phase III: Regional Supply Shortage (Extreme) — A surface water shortage is underway brought on by persistent low-flow conditions that will lead to surface water supply exhaustion if low-flow conditions persist.

Phase IV: Water Supply Crisis (Critical) — Surface water supply is exhausted.
