The Todd River flows southeast from the MacDonnell Ranges past Alice Springs, then into the western Simpson Desert, where it becomes a tributary of the Hale River and eventually drains toward Lake Eyre in South Australia.

Quick Scoop: Where Does the Todd River Flow To?

Think of the Todd River as one of Australia’s most famous “usually-dry” rivers, carving a path through the Red Centre before fading into the desert and, in big water years, joining a much larger inland drainage system.

1. Start: MacDonnell Ranges

  • The river begins in the MacDonnell Ranges in central Australia.
  • From there it drops down toward the Alice Springs area, crossing rocky country and desert landscapes.

2. Through Alice Springs

  • It flows past the historic Alice Springs Telegraph Station and then runs right through the middle of Alice Springs.
  • The river then squeezes through a narrow gap in the hills called Heavitree Gap at the southern edge of town.

Locals often treat a flowing Todd as an event – people head to bridges and the riverbank to watch the rare water surge through town.

3. Into the Desert

  • After leaving Alice Springs, the Todd continues into the western part of the Simpson Desert, across very arid country where it is dry most of the time.
  • In this region, it is an ephemeral river, meaning it only carries water after significant rain.

4. Final Destination: Lake Eyre System

  • Further downstream, the Todd becomes a tributary of the Hale River.
  • The Hale River then carries this flow onward in the direction of Kati Thanda–Lake Eyre in South Australia, which is the ultimate inland basin the Todd is part of in major flood years.

Mini FAQ

  1. Does the Todd River always reach Lake Eyre?
    • No. Because it flows so rarely and the climate is so dry, water often soaks into the ground or evaporates before travelling the full path, but hydrologically it belongs to the Hale–Lake Eyre system.
  1. Why is it famous if it’s usually dry?
    • It’s iconic for Alice Springs, central to local culture, and even hosts events like the Henley-on-Todd “boat race” in the dry riverbed.

TL;DR: The Todd River runs from the MacDonnell Ranges through Alice Springs and Heavitree Gap, out into the Simpson Desert, then feeds the Hale River, which ultimately drains toward Lake Eyre in South Australia.
