Harding Dam is a crucial drinking water source for the West Pilbara Water Supply Scheme, which provides water to Karratha, Dampier, Roebourne, Wickham and Point Samson.

To protect water quality, it is important that visitors to the dam avoid the 2 kilometre reservoir protection zone around the high water mark of Harding Dam, where access is not permitted. Only bushwalking is allowed within the source protection area around the catchment.
