Lake Argyle is a massive man-made reservoir in the Kimberley region of Western Australia, located approximately 75 kilometres by road from Kununurra via the Victoria Highway. Created in 1971 when a dam was built across a gorge in the Carr Boyd Ranges to harness the Ord River, it is Australia's largest man-made lake and is technically classified as an inland sea given its scale. The lake holds around 10,000 gigalitres of water and contains approximately 70 unique islands, with depths reaching 45 to 48 metres in places.

The lake is officially classified as "Partially Smooth Waters," meaning conditions are relatively calm year-round, making it accessible to paddlers of varying experience levels. However, the sheer size of the lake demands respect — it is vast enough that the horizon can barely be seen from some points, and open-water crossings in a small craft require careful planning. A significant hazard throughout the lake is submerged dead trees, particularly when water levels are low. Many are visible, but others lurk just below the surface and pose a serious risk to watercraft. Paddlers are strongly advised to purchase a navigation chart from the resort before heading out.

The lake is home to an estimated 35,000 freshwater crocodiles, and paddlers should be aware of their presence at all times. Saltwater crocodiles are not a known concern in relation to the lake itself. Wildlife encounters can include wallabies on the lake's islands and large flocks of birds.

For sea-kayak-style craft, the lake offers excellent island-hopping opportunities and exploration of numerous side gorges and bays. A popular paddling alternative is the Ord River below the dam wall — a roughly 55-kilometre trip downstream to Kununurra, passing through gorges inaccessible by vehicle.

Kayak, canoe, and stand-up paddleboard hire is available at the lake through operators based at the Lake Argyle Resort area. Rental packages include the watercraft, paddle, and life jacket. Maritime regulations require all paddlers to wear life jackets at all times, and a safety briefing is provided before entering the water. Half-day and full-day hire options are available. The Discovery Holiday Parks resort on-site also offers equipment hire and can provide maps and safety information. A boat ramp is available for those launching their own craft.
