River crossings
Most river crossings are conducted safely and successfully, however unfortunately not all crossings go so well.
When attempting a river crossing, these three crucial decisions will help you to reduce the risk:
1. Should you cross?
Crossing alone is hazardous and it is not recommended that you get yourself into a river crossing situation if you are alone.
2. Where should you cross?
Never cross a river in flood – 80% of river crossing drownings have occurred when the river has been in flood.
Check the speed of the river, look downstream for run out hazards and see if there are good entry and exit points
Avoid crossing on a bend, above a place where another stream joins the river and where the water is dirty and cloudy.
3. How should you cross?
Check your clothing and equipment.
Avoid loose bulky clothes.
Wear your boots or shoes (DO NOT WEAR AT THE BEACH).
Try to keep the gear you are carrying in your pack/day pack dry. Make sure that it is all in plastic bags.
When crossing always:
keep your body side on to the current;
take small shuffling steps;
move diagonally downstream with the current to conserve your energy;
have a leader to control the crossing make sure that everyone can hear instructions before you get into the river;
have the strongest people at the upstream end to break the flow for the others;
have the upstream person just slightly ahead of the person next downstream and so on down the line.
If the crossing does not go as planned:
Stay linked up and back up slowly out of the river. Do not break the link until everyone is into very shallow water.
Swimming - Thomas
Swimming spots in rivers can be great places in summer. If you pick your spot carefully and check it out each time you swim there you can keep yourself and your friends safe.
Swimming in a river is different from swimming in a pool or in the sea. Swimmers often underestimate the power of the river or overestimate their own abilities.
The river bottom is irregular and can change from day to day. It is often difficult to tell how deep a certain part of the river is. Many people are seriously injured each year jumping into water that is too shallow.
Stay safe when swimming in rivers by:
Learn swimming and swimming survival skills.
Always swim as part of a group.
Check for hazards both where you are swimming and downstream.
Do not mix swimming with alcohol or drugs.
Check out any jumping spot thoroughly before jumping. Do this by getting in the water and physically checking the depth and the whole landing area. Do this every time you visit a jumping spot to check that nothing has drifted into the landing zone since you were last there.
Floods - Coby
A significant danger occurs when our rivers, creeks and streams flood. Debris and fast flowing currents can cause banks to become unstable and even a small rise in the water level can dramatically change the way a river flows.
When inland waterways are in flood it is important to keep out of the water wherever possible and keep well away from river and creek banks, they can become weak and subject to collapsing.
