What it does
The Lakes Sorell and Crescent Conservation Act 1901 is a Tasmanian water‑allocation and cost‑sharing statute that confers on the responsible Minister the power to construct, operate and maintain works to conserve or divert water from two interconnected lakes (Lake Sorell and Lake Crescent) and the Rivers Interlaken and Clyde. Its core mechanical function is to subordinate the State’s diversion rights to a prior daily entitlement of 100,000 cubic yards held by the Trustees of the River Clyde for the purposes of the Clyde Water Act 1898. Only after that priority volume is available to the Clyde trustees may the Minister divert up to 90,000 cubic yards per 24 hours for delivery to the Trustees of the Midland Water District under the Midland Water Act 1898. The Act also authorises the Minister to construct direct channels from either lake to the River Clyde, but in that case a separate meter must be installed at the intake and the Minister’s take is again limited to 100,000 cubic yards per day for Clyde‑district purposes. Conservation of the lakes is permitted only when the flow in the River Clyde at a gauge near Bothwell exceeds 100,000 cubic yards per 24 hours, and the power to conserve continues while that threshold remains exceeded.
The Act creates a distinctive hybrid of public works and trustee‑based cost recovery. The capital cost of all works is initially paid from parliamentary appropriations (section 8). However, the two trustee bodies are then required to pay annual interest of 5 per cent on defined portions of that capital cost into the Public Account. The Clyde trustees pay 5 per cent on half the cost of any works that conserve water in the lakes, plus 5 per cent on the whole cost of any works that convey water directly from Lake Sorell to the River Clyde. The Midland trustees pay 5 per cent on half the cost of conservation works and on the whole cost of all works that divert water from the lakes to the delivery point for the Midland Water District. The Auditor‑General certifies the capital cost and each trustee’s proportionate share, and that certificate is binding and final. The Minister must maintain all works in proper repair, with expenses borne by the two trustees in the same proportion as the interest obligations under section 9. Landowners whose property is harmed by the construction of works or by any exercise of the Minister’s powers are entitled to compensation, determined as if in a disputed claim under the Land Acquisition Act 1993.
