Orange County water supply reservoir water levels Available information as of 9:00 AM, Thursday, May 28, 2009 Lake Orange • Water level is full and spilling • Water storage capacity is at 100% (475 million gallons) • Approximately 141 days of water supply remaining (at Capacity Use specified release rate). • The Hillsborough gage indicates that current Eno River flows are at approximately 12 cfs (7.76 mgd). This flow represents a level that is approximately 60% of the historical median flow level (21 cfs) for this day of the year. • At this time of year, seasonal rains have ended and there is very little base flow to the Eno. How late in the year Capacity Use restrictions and manual releases from the reservoirs are initiated is based on the hit or miss nature of the thunderstorms which break up the 7-day low flow (below 10 cfs daily average) period that triggers the maximum withdrawal and minimum stream flow requirements • Orange Alamance continues the operation of its water plant five days a week (Monday- Friday) with average withdrawals of 300,000 gallons per day.
