The Carson River is a remote and ecologically significant waterway flowing through the Kimberley region of Western Australia, situated near the southwestern boundary of the Drysdale River National Park. This river system is characterized by its isolation and diverse freshwater habitats, supporting a unique assemblage of native fish species. The river's course features distinct upper and lower sections, each with different ecological characteristics that influence fish distribution. Access is challenging due to the rugged terrain and its location within a vast, sparsely populated region, making it a destination for adventurous anglers seeking a wilderness fishing experience.
