The Hura-Mafa River came into being when the Great Spirit Mata Nui's camouflage system was accidentally activated during the Great Cataclysm and created the island of Mata Nui. The river ran northward from Mount Ihu to Naho Bay, emptying into the bay by means of the Naho Falls.
The river was cleared by the reawakened Bohrok swarms, and was wiped from existence by Mata Nui reawakening.
- Track two of the BIONICLE Power Pack was titled "Hura-Mafa Flow," after the river.
- In BIONICLE: Encyclopedia Updated the Hura-Mafa River is misspelled as "Hufa-Mafa River."
