29 APRIL NEW ZEALAND GAZETTE 1085

(b) For Lake Te Anau, above 202.7m, in accordance with the following maximum durations, minimum intervals, and specified ratios for the ranges of levels set out:

(3) Where the ratio derived from dividing the interval between the lake level moving below a particular range of level and returning to that range of level by the duration that the lake was in that range of level immediately prior to the interval:

(a) Results in a ratio greater than or equal to the specified ratio, then the guidelines are deemed to be complied with;

(b) Results in a ratio less than the specified ratio, then subject to subclause (4) of this clause, the interval occurring after a particular duration shall be added to that duration along with the duration occurring after that interval, in order to determine the duration for which the specified ratio must be achieved.

(4) The period of duration within any range of level, including accumulations as provided for in paragraph (b) of subclause (3) of this clause, shall not exceed the relevant maximum duration.

6. The Low Operating Ranges—(1) Subject to subclause (2) of this clause, the Low Operating Ranges are:

(a) For Lake Manapouri levels from 175.86m to 176.8m, with an absolute minimum level of 175.86:

(b) For Lake Te Anau from 200.86m to 201.5m, with an absolute minimum level of 200.86:

(2) For the purposes of the Low Operating Ranges outlined in subclause (1) of this clause, the Corporation shall use its best endeavours to:

(a) Not exceed the maximum durations for the individual ranges of levels specified;

(b) Avoid lake levels below 201.1m for Lake Te Anau, and below 176.2m for Lake Manapouri, during the equinoctial periods (March, April, October and November);

(c) Not continuously exceed a period of 365 days, twice the maximum duration specified for any particular range of level; and

(d) Ensure the rates of drawdown do not exceed the natural rates of drawdown averaged over four days, being 0.05m per day for Lake Manapouri, and 0.03m per day for Lake Te Anau.

(3) The parties record that:

(a) In the period of natural record the level of Lake Manapouri has been below the absolute minimum level of 175.86m; and

(b) These guidelines are based on the mean of three extreme events during the period of natural record and may result in low ranges of level being experienced more often than would have occurred naturally.

7. Gate Opening and Closing Procedures—(1) The Parties have agreed upon and adopted gate opening and closing procedures which are designed amongst other things:

(a) In the case of the Lake Te Anau Control structure, to reduce or eliminate scour action on the upper Waiau River banks, to facilitate repair following periods of extremely high flow, and to facilitate the successful spawning of salmonids; and

(b) In the case of the Lake Manapouri Control structure, to reduce potentially dangerous increases in river flow downstream of the gates, to bypass flood flows from the Mararoa River in such a manner as to prevent dirty debris-laden water from entering Lake Manapouri.

(2) It should be noted that the procedures referred to in subclause (1) of this clause are modified from time to time by agreement between the Parties.

8. Benchmarks—For the purposes of this notice:

(a) The level of Lake Te Anau at any time shall be determined by reference to the Department of Survey and Lands Information Benchmark Z58, national grid co-ordinates (176 284) yards east (319 170) yards north, which is adjacent to the lake water level recorder and staff gauge, which benchmark shall be deemed to represent a height 205.127 metres above mean sea level; and

(b) The level of Lake Manapouri at any time shall be determined by reference to the Department of Survey and Lands Information Benchmark Z47, National grid co-ordinates (170 051) yards east (305 873) yards north which benchmark shall be deemed to represent a height of 208.910 metres above mean sea level.

9. Consequential revocation—The notice entitled “Manapouri-Te Anau Development Act 1963” dated 1 March 1990 and published in the Gazette of 8 March 1990 at pages 701/702, is hereby consequentially revoked.

Signed at Wellington this 14th day of April 1993.
