April’s Water Supply Outlook is Published

The ICPRB Section for Cooperative Water Supply Operations on the Potomac (CO-OP) has issued its first Water Supply Outlook for this year. The outlook, issued monthly between April and October, assesses low-flow conditions in the Potomac basin and the water supply system’s ability to meet drinking water demands. For April, the report projects a one to four percent probability that the natural flow of the river will drop below 600-700 million gallons per day, at which time releases of stored water may be needed to meet demand and environmental flowby targets. The low probability is factored from above average groundwater levels, river flow, and precipitation. The wet conditions in the first quarter of the year build on last year’s record-breaking precipitation. Learn more…
