Creek
A natural watercourse, usually smaller than a river, that carries water along a channel. A creek may flow year-round, only after rain, or be dry for long periods.
In Australian bushwalking, creek commonly means a small stream or its channel, including one that is dry when you visit. Some named creeks are substantial waterways, so the name does not tell you how deep, fast or safe the water is. Creeks usually follow lower ground and collect runoff from surrounding slopes and gullies. Flow can change quickly after rain, including rain upstream that you cannot see.
In the wild
"The track follows the creek through the valley before crossing at the bridge."
Why it matters
Safety: Never enter floodwater or cross a swollen or fast-flowing creek. Depth, current, slippery rocks, submerged debris and unstable banks can be hard to judge. Use a safe bridge or an alternative route; turn back if conditions are uncertain. Check weather, flood warnings and park alerts, including conditions upstream. Avoid camping in creek beds or on low banks. Untreated creek water may contain pathogens; carry adequate water and use an appropriate treatment method. Treatment does not make chemically contaminated water safe.
Rex's tip: A blue line is a clue, not a promise of a drink or a safe crossing. If it's flooded, forget it.
