🌿 Understanding the MacKenzie River – and what’s happening right now 💧
We have recently had some enquiries about the MacKenzie flows and water availability, so we wanted to share an update, and a bit of local context.
First, to clear up a common mix-up we often hear:
👉 MacKenzie Creek is actually the town, while the MacKenzie River is the waterway.
💧 Current conditions
With very low inflows into Lake Wartook over the past few years, maintaining a constant flow down the MacKenzie River would impact water availability for future years for all users including stock and domestic supply.
At present:
❌ We are not watering the lower MacKenzie River (from Distribution Heads Weir to the Wimmera River) due to low storage levels in Lake Wartook.
💧 Any flows released now would likely be lost into sandy riverbed soils before reaching this lower section.
✅ Watering is focused upstream of the Distribution Heads (Laharum) where it can be used more efficiently and to support important drought refuges.
The good news is that flows can return to the lower river when Lake Wartook levels improve and rainfall increases water availability. Encouragingly, inflows from Bungalallay Creek in October-November 2025 did reach the lower MacKenzie River.
With the recent rain, we’re hopeful conditions will continue to improve 🌧️
📜 A little history
The MacKenzie River rises in the Grampians (Gariwerd) and flows north-west to the Wimmera River, forming an important part of the region’s landscape. For thousands of years, it has been significant to Traditional Owners, providing water, food and connection to Country.
Since European settlement, it has also played a key role in:
💧 Supporting Horsham’s water supply (with Lake Wartook built in the early 1900s)
💧 Agriculture and communities across the Wimmera
💧 Sustaining local ecosystems
Like many rivers in the Wimmera, the MacKenzie River is naturally variable, and managing water means balancing environmental needs with essential town supply, especially during extended dry periods.
🤝 Let’s keep the conversation going
We understand how important the MacKenzie River is to local communities.
If you’d like to discuss this further, please contact our office to make an appointment, we’re always happy to chat.
Thanks for your continued care and interest in the MacKenzie River 💙
