Targeting big cod in Lake Eildon?

THE pursuit of big Murray cod in Lake Eildon has entered a new era with the rapid advancements in LiveScope sonar technology. Once a game of patience and intuition, modern anglers now have access to real-time imaging that reveals underwater structures, fish movement, and even how cod react to different lure presentations. LiveScope: The Cutting Edge of Sonar Technology LiveScope, developed by Garmin, has revolutionised the way anglers approach fishing. Unlike traditional sonar, which provides historical data, LiveScope offers live, forward-facing imaging, allowing anglers to watch fish behaviour in real-time. This is especially useful when targeting big cod, as their ambush feeding strategy means they often hold tight to structure, waiting for the perfect moment to strike. New developments in LiveScope+ and LiveScope XR have significantly improved: • Target separation – Clearer distinction between fish and submerged structure. • Depth range – The XR model extends visibility to greater depths, ideal for deeper sections of Lake Eildon. • Image clarity – Enhanced resolution makes it easier to detect large fish near snags. This allows anglers to not only locate fish but to also watch their reaction to different lures and retrieve styles, fine-tuning their presentation in real-time. Lake Eildon Cod: Current Conditions & Techniques As we move through March 2025, the water level in Lake Eildon remains stable, with clearer water in main arms and slightly murky conditions in feeder creeks after recent rain. Water temperature sits around 21–24°C, which is still within the active range for big Murray cod. Using LiveScope, anglers have been locating cod holding in deeper water (6-10m) near submerged timber and rocky drop-offs. During low-light periods (early morning and dusk), shallow flats and points have been productive. Key techniques include: • Large Swim baits (200-300mm) – Cod have been seen tracking swim baits for long distances before committing, making real-time observation crucial. Adjusting retrieve speed has been the difference between a follow and a strike. • Slow-Rolled Spinnerbaits – Heavy 1-2oz spinnerbaits with large single Colorado blades have been effective in deep timber. Watching how cod react to these baits on LiveScope has helped anglers refine their retrieves. • Surface Lures at Night – Big paddlers and wake baits have drawn explosive surface strikes when cod are seen rising towards structure in shallower areas. LiveScope has dramatically changed the way cod fishing is approached in Lake Eildon, taking much of the guesswork out of the equation. However, while technology helps find fish, understanding behaviour, water conditions, and lure presentation remains key. If you’re targeting big cod this season, upgrading to the latest sonar tech could be the edge you need.
