Many natural rivers in Australia dry up during the winter. The Tully River is different. Daily releases from the 88 MW Kareeya Hydro power station keep the water rushing down the gorge every day of the year.
Does the Tully River have rapids all year round?
Yes. The Kareeya Hydro power station releases water daily, guaranteeing flow regardless of the season.
This means you can book a tour in the middle of the dry season and still experience Grade 3 and 4 rapids. The dam controls the river level, making the Tully River a highly reliable rafting destination.
When is the wet season on the Tully River?
The wet season runs from December to April.
During these months, heavy rainfall adds to the dam releases. This creates even more powerful flows and larger waves. The water temperature is also warmer during this period.
Is it better to raft in the wet season or dry season?
Both seasons offer excellent rafting, but the wet season provides slightly larger rapids and warmer water.
If you want the maximum thrill, aim for December to April. If you travel between May and November, the dam releases ensure you still get up to 3 hours of turbulent water.
How cold is the water in the Tully River?
The water is tropical, but it can feel cool during the winter months (June to August).
Because the water comes from a deep dam, it remains relatively cool. The wet season offers warmer water temperatures. You wear a life jacket or wetsuit over your swimwear to stay comfortable while on the river.
Will my trip get cancelled due to water levels?
Cancellations due to low water are extremely rare because the dam regulates the flow.
The power station must release water to generate electricity. This ensures the river always has enough depth for standard inflatable rafts carrying up to 7 passengers.
What time of day does the tour operate?
Full-day tours generally pick up late morning to align with the scheduled water releases.
Pickup times from Cairns and Mission Beach vary by operator, and some start as early as 6:30 am. Tours are timed to the daily dam release.
