Storaqe Accounts

Storage accounts. which will be located either in the
permanent pool or in the flood control pool. or both. depending
on the reservoir storage scenario employed; will be made
available in the following amounts:

In Scenario A. there are storage accounts representing the
original 1979 requests for 305 a.f. of space plus 50 a.f. each
for Mt. Carbon and Lakewood. These six accounts are within the
permanent pool. The state would store under its rights in
priority to the extent that space is available (vacant) and
release water from its account whenever any entity was able to
store under its rights.

In Scenario B. those same six storage accounts remain
within the pcrm~nent pool and an additioual five stO[dY~
accounts are located within the flood control pool. which rides
on top of the permanent pool. It is suggested that Agencies
operate off the top or from the flood control account first
prior to operating in the permanent pool. The state would
operate as in Scenario A. The study consultant could also
recommend that the state have an actual storage account of a
certain size if such appeared to be a more desirable
alternative in terms of minimizing fluctuations. This account
would be in the flood control pool.

In Scenario C. there are no storage accounts in the
permanent pool. Rather. there are seven storage accounts (one
for each entity) for 2625 a.f.. all located in the flood
control Fool. The state would operate as in Scenario Band
have some type of account.

Scenario D is the same as Scenario C. except that the state
would now have an actual account for 2000 acre feet and would
not attempt to operate solely to minimize vacant storage space.
