041 stream reservoirs (Corporation Lake and Lake Ben Johnston) rather than Lake Orange. This was not approved because of the variable water level at these reservoirs. During times of prolonged drought they are dependent for water on releases from Lake Orange. A second alternative is to retain Lake Orange water level as a primary indicator for action but also, under specified condi- tions, use the flow volume and rate in the Eno River as an additional or substitute factor. The Manager, in consultation with the N. C. Division of Water Resources recommends the latter. If approved the concepts to be incorporated into Article 3 of the ordinance would include defining the water supply stages as: 1. NORMAL STAGE - when Lake Orange is 80% to 100% of usable storage and instream flow, as measured the Hillsborough U. S. Geological Survey Gage, is in excess of 1.1 MGD. 2 . ALERT STAGE - when Lake Orange usable storage is between 70% and 80% or in instream flow is in excess of 1.1 MGD. 3 . WARNING STAGE - when Lake Orange usable storage is between 50% and 70% and instream flow is less than 1.1 MGD. 4. DANGER STAGE - when Lake Orange usable storage is 40% to 50%. 5. EMERGENCY STAGE - when Lake Orange usable storage is 30% to 40%. 6. CRISIS STAGE - when Lake Orange usable storage is 10% to 30% (10% and below is considered not usable) . An ordinance incorporating these changes is being drafted by the County Attorney and will be ready for Board review December 16, 1986. IMPACT: The change would refine the administration of the ordinance and provide more clarity to the citizenry which is affected by the conservation measures. Restrictions could be scaled back from mandatory to voluntary conservation if approved. RECOMMENDATION(S) : Approved the ordinance as revised.
