Orange County water supply reservoir water levels Available information as of 1:00 pm, Thursday, August 30, 2007: Lake Orange • Water level is approximately 48" below full. • Water storage capacity remaining is approximately 63% (235 million gallons) • Approximately 103 days of water supply remaining (at Capacity Use specified release rate) • We are still in Stage 2 as defined by the Eno River Capacity Use Agreement West Fork Reservoir • Water level is 30" below full. Water storage capacity remaining is approximately 88.6%. More than 232 days of water supply are remaining (assuming Town's current daily demand and releases for streamflow augmentation) As of this afternoon, Hillsborough's Town Engineer has increased its release amount from the reservoir from 2.7 cubic feet per second (cfs) to approximately 4.0 cfs. This is four times their required release rate of 1.0 cfs for August. This part of a continued effort to ameliorate the drought effects on Lake Orange.
