Plans to restore water flows in the Ashburton River have been stymied by a lack of information. Currently there is no way of ascertaining how much water is abstracted or by whom; some water-takes close to the river even have no minimum flow conditions. The Ashburton Water Management Zone Committee is trying to raise flows in the river and in 2012 endorsed a plan to restore flows to a minimum of 6000 litres a second at the State Highway One recording site by 2023. At the same time a longer term goal of 10,000l/s was set for 2033. No new consents to take water from the river will be allowed until this goal is reached. However, consensus is yet to be
reached as to how to achieve these targets. Environment Canterbury senior planner Don Vattala told the committee there was “huge over allocation” as a result of consents being given at a time when there was no allocation plan in place for taking water from the river. As a result the zone committee inherited a historical allocation that was well in excess of what the river can provide. A significant number of irrigating farmers abstracting groundwater from wells hydraulically connected to the river have no minimum flow conditions attached to their consents – a fact which did not sit well with ECan commissioner David Caygill. He said a better understanding of what wells were hydraulically connected to the river was required to proceed with

the next phase of the plan. Mr Vattala said if allocation was set now it would be 50 per cent of the seven-day minimum average flow levels – equating to 6700l/s rather than the 22,195l/s currently allocated, which averages out at 16,440l/s year round. The proposed targets represent 80 per cent of the current seven-day minimum average, set to achieve the long-term goal of 10,000l/s or 50 per cent to reach the lower goal of 6700l/s. Retired hydrologist John Waugh said the problem extended beyond those wells closer to the river reaching further out on to the plains.
