It originates in the muskeg of north western Alberta, flows west to British Columbia, then curves northward and returns to Alberta, where it follows a north-northeast course towards the Northwest Territories. After passing over two main waterfalls, the Alexandra Falls and Louise Falls, it flows through the town of Hay River and discharges into the Great Slave Lake. From there, its waters are carried to the Arctic Ocean by the Mackenzie River.
Hay River has a total length of 702 km and a drainage area of 48,200 km².
Tributaries of the Hay River are the Chinchaga River, Meander River (in South Slavey: Tahchee), Steen River, Melvin River and Little Hay River. The Hay River effectively flows through the Hay-Zama Lakes. Rainbow Lake is a widening of the river itself.
Communities in the Hay River basin include Rainbow Lake, Zama City, Steen River, Indian Cabins (in South Slavey: Dzêtú) in Alberta and Enterprise and the homonymous Hay River in the Northwest Territories. There are two first nations communities in the river basin: Chateh and Meander River.
At the Alberta/Northwest Territories border, the annual discharge is 3,630,000 dam3. The only official campground along the river is at the 60th Parallel Campground.
