Orange County water supply reservoir water levels Available information as of 1:00 PM, Thursday, October 18, 2007 Lake Oran6e • Water level 83.5" below spilling. • Water storage capacity remaining is 42.1% (199.7 million gallons) • Approximately 75 days of water supply remaining (at Capacity L1se specified release rate) • Current Eno River flow at the Hillsborough gage is 2.2 cfs (1.42 mgd). This is approximately 0.5 cfs above minimum flow required by the Eno River Capacity Use Agreement, but well belo~~~ the median flow for this time of year. • Stage 4 Eno River Capacity Use withdrawal restrictions have been in effect since September 28~'. Stage 5 withdrawal restrictions go into effect when the water level reaches 89" below spilling. Given the current rate at which the water level is dropping and without the rainfall necessary to either raise water levels or slow the rate of subsidence, it is anticipated that Stage ~ restrictions will go into effect within the next 10 days. ~~est Fork Reservoir (as of 10/12/07} • t~'ater level is 60" below spilling • Water storage capacity remaining is 69.1% • Approximately 228 days of water supply remaining {assuming Town's current release rate (3.3 cfs, 2.13 mgd) and demand. • Since 9i'11/07, the Town has been releasing a level of flow into the river sufficient to meet or exceed that which is required for its own use and its minimum instream flow release. • Hillsborough's water customers are not currently under any prohibitions or restrictions on water use. Hillsborough's «~ater conservation ordinance calls for voluntary restrictions will go in place when remaining storage falls to 180 days of l~~ater supply. However, it is possible that the Hillsborough Board will call for voluntary restrictions before that time in answer to Governor Easley's call for statewide water conservation. O«'ASA Reservoirs • Water level at Cane Creek Resei-~~oir is 117.8" below full • Water level at University Lake is 92.5" below full • Total remaining water storage capacity is approximately ~ 1.5 • Approximately 175 days of water supply remaining {at current 30-day average daily demand [8.9 million gallons per day]) • On September 27, 2007 OWASA (followed by the local governments having jurisdiction over OWASA customers) declared a "Stage I Water Shortage", a mandatory regulation of uses of water considered extraneous which will be in effected until terminated. The O«~'ASA Board of Directors has called a special meeting for Oct. 18t~', at 7:00 PNI to discuss declaring a "Stage II Water Shortage". Stage II provisions add additional restrictions to those of Stage I, including increased conunodity surcharges to water use in excess of specified flows (800 gallons per day residential, down from 1000 gallons per day residential), no spray irrigation except for those selling plants, only commercial vehicle washing operations where 50% of water is recycled.
