Important river crossing information

The Okuku River normally flows at an average of 1 ½ cm3/sec through the low rainfall months surrounding summer (December to May) making it easy to cross as it is only approximately 1 to 1 ½ feet deep. Through the higher rainfall months surrounding winter the average river flow climbs but still regularly offers low and safe fordable flow rates of 3 to 5 cm3/sec. Be aware that this river can rise at an alarming rate, it frequently floods to 25 cm3/sec+ and in a heavy storm it has been recorded to flow at over 260 cm3/sec! If the flow is up you can often still find shallow paths to cross in some of the braided sections downstream of the ford keeping in mind that floods often change these braided locations and they may not be available all of the time. Admitting defeat and turning back may be your only option in cases when the river unexpectedly rises and/or flood water has removed braids and cut channels too deep to cross. Where to draw the line is entirely dependant on your comfort level of water crossings, here are some rough guidelines for safety:

Rough guidelines for safe crossing

  • 1 to 3 cm3/sec : Easy and safe to cross
  • 3 to 5 cm3/sec : Safe to cross, may get a little deep/swift in sections
  • 5 to 8 cm3/sec : Can be challenging, you may need use braids to get across
  • 8 cm3/sec + : Potentially unsafe to cross

The above recommendations may be a little conservative for those that are comfortable with big river crossings, but better to keep this on the safe side.

To find the Okuku flow rates visit the Ecan website and use the Okuku Fox Creek flow report. The flow station is situated at the end of Taaffes Glen Road by the Fox Creek tributary spilling from the Okuku Range.

Other attributes of the Okuku river

  • The river base is often lined with large boulders brought down in floods
  • When the flow is high it can be discoloured making the bottom hard to see and hard to avoid boulders
  • Due to the valley gradient the river can often be quite swift above 5 cm3/sec
