Introduction
Jordan Lake operates with two independent accounts for the volume of water within the
reservoir pool. These accounts are for water supply and water quality augmentation.
These separate pools are analagous to separate checking accounts in a bank.
Funds are added or subtracted from each account without affecting the balance in the other
account. Similarly, water that flows into Jordan Lake is assigned to the two pools
based on the percent of the total flow. Water that flows out of the lake, either through
the dam (water quality augmentation) or through water supply intakes, is subtracted from
the appropriate volume of storage within the pool.
Need for a Basin Model
A model of the Cape Fear River Basin is needed to assist decision makers involved in
the allocation and interbasin transfer processes, as well as providing a sound basis for
management of the lake during droughts. Without a functioning model, the
impacts of proposed IBT's and efficient drought management of the pool must be left
inevitably to subjective estimation, ie. guesswork.
