65 Dam operation during floods and spills

(1) The operation of Keepit Dam during times of flood and spilling of water is to be undertaken in a manner that maintains the safety of dam infrastructure.

(2) Providing it is consistent with subclause (1), operation :

(a) should leave the storage at full supply level at the completion of the flood or spilling of water,

(b) during floods should ensure the general rate of increase of outflow from the water storage does not exceed the rate of increase of inflow to the water storage, and

(c) should aim to lessen downstream flood damage, where possible.

Note: Split Rock Dam has a free overflow spillway and as such there are no flood operation procedures.
