This article begins by presenting the commonly used drought management metrics of “safe yield” and “days of supply remaining”, and goes on to discuss a risk‐based drought management plan that incorporates forecasting to offer a less expensive and more reliable alternative. The key to improved operating efficiency is for a utility to incorporate forecasting into its operating rules to account for seasonal changes, storage levels, and future inflow and demand. The article discusses developing drought triggers and risk management approaches that have been used by several East Coast cities.
