Successful Waiau River Bar Opening Amidst Bluecliffs State of Emergency

Civil Defence Controller Simon Mapp has provided an update on the local State of Emergency in Bluecliffs, highlighting a significant development in the community’s defense against erosion. On Thursday, 22nd February, contractors for Environment Southland completed a crucial operation by cutting into the gravel bar at the mouth of the Waiau River, a measure taken to mitigate the erosion threatening properties in the Western Southland coastal community.

This strategic intervention, part of the broader efforts under the local State of Emergency declared for Bluecliffs, was aimed at realigning the river’s path into the sea. The goal is to delay further erosion by modifying the natural flow, thus protecting the frontage of the community’s properties. Over the past two weeks, approximately 30,000 cubic meters of material were moved to accomplish this task.

Controller Mapp expressed his gratitude towards everyone involved in the operation, acknowledging the challenging battle against nature’s forces. “The team has performed commendably under difficult circumstances,” he said, reflecting on the struggle to work with and against natural elements.

The effectiveness of the bar opening will be assessed over the coming days, with increased river flow and weather conditions playing critical roles in this evaluation. Meridian Energy has also played a part by managing water release from Manapouri Lake’s control structure, ensuring the safety of contractors during the operation.

The community is urged to exercise caution, especially near the newly opened bar east of Bluecliffs, and to adhere to restricted access points for safety. The complexity and technical nature of the bar opening, combined with the dynamic environmental conditions at Bluecliffs, leave the long-term success of this intervention uncertain.

Looking ahead, the focus will shift to ongoing conversations with the community about the future of the area and the commencement of material removal at the tip site, which is expected to begin in the coming weeks.

Summary Points:

• Environment Southland’s contractors have completed the opening of the Waiau River bar as part of the Bluecliffs State of Emergency efforts.
• The operation aims to realign the river to delay erosion threatening properties in Western Southland.
• The effectiveness of the intervention will be evaluated in light of increased river flow and upcoming weather conditions.
• The community is advised to avoid the dangerous area near the new opening and adhere to safety restrictions.
• Future plans include further community engagement and the start of material removal at the tip site.
