Sharing water for a sustainable future
Water is one of our most valuable resources in the Hills and Fleurieu. It supports farms, wildlife and communities and it’s something we all share. Managing it responsibly is essential to keep our landscapes healthy and productive.
Dams play an important role in storing and distributing water, but changes to dams can have far-reaching impacts. Altering a dam without approval can reduce water availability for neighbours, dry up creeks, and put pressure on native ecosystems.
Due to the high number of existing dams and the potential impacts on environmental flows, a moratorium has been in place across the Mount Lofty Ranges since 2013. This means new dams cannot be built, and existing dams cannot be enlarged. Other modifications to existing dams generally require a permit. This measure helps ensure water is shared fairly between farms, communities and the environment.
Late summer and early autumn are an ideal time to inspect dams, as lower water levels make it easier to spot issues such as erosion, cracks or structural wear. While this is a good opportunity for maintenance, it’s important to understand which works are allowed and which require approval.
“Every drop counts,” said Paul Wainwright, Team Leader Water Resources, Landscapes Hills and Fleurieu. “Water is a shared and finite resource. Thinking downstream and seeking the right approvals helps ensure our limited water resources are managed fairly and carefully across the region.
“Not every activity needs a permit - some minor works can be carried out by following approved Recommended Practice Guidelines. But if you’re unsure about your obligations, it’s best to contact your local landscape board before starting any work.
“These guidelines help landholders manage water responsibly without unnecessary red tape. Before you start, however, it’s important to check what applies to your situation,” he said.
Permits and Recommended Practice Guidelines aren’t just about compliance - they’re about fairness and sustainability. They help protect waterways, ecosystems, wildlife, and primary production, and ensure that everyone downstream gets their fair share. By following the rules, you’re helping the whole catchment flourish.
