Swimming in Lake Argyle

With water temperatures hovering around 30 degrees Celsius in summer and 21 degrees Celsius during winter, swimming is possible in the freshwater of Lake Argyle all year-round.  

Outside of your own boat, access to the lake is possible at the Lake Argyle boat ramp or via a short walk from the village that leads to the water’s edge. 

The Lake Argyle Swim

Since 2006 the Lake Argyle Swim has been held in the lake, starting with a small group of fundraising swimmers from New South Wales, growing into one of the Kimberley’s favourite community-based sporting events.

Is it safe to swim in Lake Argyle?

Although Lake Argyle is home to the world’s largest population of Johnston River Freshwater Crocodiles (Crocodyllus Johnstoni), these prehistoric creatures are timid and generally considered not dangerous to humans. The locals at Lake Argyle who swim in these waters respect the fact this is the Crocodiles’ natural habitat.   

Like all wildlife, Freshwater Crocodiles should not be interfered with in any way. Freshwater Crocodiles should not be fed, caught or approached as they may become aggressive when in a compromised situation. Although Freshwater Crocodiles eat insects and small fish there have been instances where accidental injury is caused through mistaken identity or unnecessary handling.   

Freshwater Crocodiles are often found in secluded bays and inlets with gravel or sandy banks where they may nest or bask in the sun. These areas should be avoided if looking for a place to swim or camp.  

Several of the daily Lake Cruises stop for a refreshing swim some distance from the shore in the deeper waters of the lake where crocodiles are not likely to be present. 

Are there Saltwater Crocodiles in Lake Argyle?

Freshwater Crocodiles can only live in freshwater, whereas Saltwater Crocodiles (Estuarine Crocodiles –Crocodyllus Porosus) can survive in fresh or saltwater. While ‘salties’ can survive in Lake Argyle, only the occasional small one has been found entangled in fishermen's nets, the largest being approximately 1.5 metres long!  

It is believed these are only small individuals that have travelled long distances overland during a big wet season and have ended up in the lake. There is no evidence of Saltwater Crocodiles breeding in Lake Argyle. The Locals consider the water safe, but swimming remains an activity undertake at your own risk.
