The Ōhinetamatea River, also known as Saltwater Creek, is a river located in the Westland District of New Zealand's West Coast region. It originates on the northern flank of the Copland Range and flows northwards. A significant feature of this watercourse is a 72-meter-high waterfall located approximately 700 meters from its source. The river's overall length is about 1,700 meters. Topographic map sheets for the area are available from Bivouac Outdoor. The general coordinates for Saltwater Creek are -43.50213758. The river's proximity to the Copland Range suggests a scenic, mountainous setting, though the short length and presence of a major waterfall indicate that navigable sections for paddling are likely limited and require careful scouting and expert local knowledge regarding put-in and take-out locations to avoid hazardous areas.
