(1) An annual high flow tally and an annual supplementary water tally shall be kept for the purpose of making available water determinations for supplementary water access licences in this water source.

(2) At the start of each water year the annual high flow tally and the annual supplementary water tally shall be set to zero.

(3) For each day during the water year when flows are sufficient to permit extraction of water by supplementary water access licences in accordance with clause 51 a volume, calculated according to the following formula, shall be added to the annual high flow tally:

"C" is the lesser of the daily flow at flow reference site 3 and 2,040 megalitres.
"D" is the volume of water extracted by supplementary water access licences on that day.
