<br />Orange County water supply reservoir water levels <br />Available information as of 10:00 AM, Thursday, September 10, 2009 <br />Lake Orange <br />• Water level is 12" below spilling <br />• Water storage capacity is at 89.5% (467 million gallons) <br />• Approximately 131 days of water supply remaining (at Capacity Use specified release rate). <br />• The Hillsborough gage indicates that current Eno River flows are at approximately 2.8 cfs <br />(1.81 mgd) and supplemental flow from Lake Orange supplemental flow from Lake Orange <br />has increased slightly over the last two weeks. This flow represents a level that is <br />approximately 33% of the historical median flow level (8.5 cfs) for this day of the year. <br />• At this time of year, seasonal rains have ended and there is very little base flow to the Eno. <br />We have experienced little thunderstorm activity over the last two weeks, so the remaining <br />storage in both Lake Orange and the West Fork Reservoir are dropping faster over this <br />period than has been the case for most of the summer. Stage I Capacity Use restrictions on <br />withdrawals and requirements for minimum instream flow have been in effect for <br />approximately two months. <br />• Orange Alamance continues the operation of its water plant five days a week (Monday- <br />Friday) with average withdrawals of 350,000 gallons per day, an increase of 50,000 gpd <br />since last year. <br />West Fork Reservoir (as last reported 9/1/2009) <br />• Water level is 9" below full <br />• Water storage capacity remaining is approximately 97.1 <br />• Approximately 293 days of water supply remaining, assuming Town's current 30 day <br />average water consumption rate (1.25 mgd). <br />• Hillsborough's minimum release for instream flow is 1.0 cfs (0.64 mgd), though the Town <br />has been releasing 2.4 cfs to less the impact of releases on Lake Orange. <br />OWASA Reservoirs (as last reported 9/9/2009) <br />• Water level at Cane Creek Reservoir is 4'-3" below full. <br />• Water level at University Lake is 2'-1" below full. <br />• Total remaining water storage capacity is approximately 79.3% (2.83 billion gallons) <br />• Approximately 308 days of water supply remain with no additional rainfall (at the current 30- <br />day average daily demand [9.17 million gallons per day]) <br />• OWASA's year-round water conservation requirements are in effect <br />
