Good inflows to Lake Glenmaggie in recent months and the wet outlook have led to controlled releases to safely manage capacity in the storage. SRW had a target date of 1 October to fill the storage.
Southern Rural Water (SRW) confirmed that with the current storage level at 98% (updated 12 October), and above-average inflows and predicted rainfall for the rest of spring, spill entitlement has been declared for all Macalister Irrigation District customers.
Manager Water Supply, Gavin Prior said that water ordered and used from the start of the season through to Thursday 29 October (updated) will now become spill entitlement. “This means water used to this date is considered over and above customers’ 100% allocation. After 29 October, we will continue to review spill entitlement on a regular basis,” he said.
He said that the spill was a welcome boost to MID customers. “We announced 100% allocation at the start of the season, to give customers the confidence to plan their irrigations in advance. Customer demand has not been as high as usual for this period due to the conditions. With a few warm days this will increase,” he said.
Given the wet conditions and predictions of above-average spring rainfall across Lake Glenmaggie’s extensive catchment, SRW made controlled releases in recent months, according to its release management plan. Manager Headworks, Ed Smith, said that the goal of the plan is to ensure the storage is full when customers need it, while protecting the integrity of the dam and minimising the risk to communities downstream, from flooding.
Lake Glenmaggie daily storage levels can be found on the Lake Glenmaggie page. SRW will continue to manage the volume of water stored in Lake Glenmaggie based on predicted rainfall and catchment conditions.
