The Kedumba River, a perennial river that is part of the Hawkesbury-Nepean catchment, is located in the Blue Mountains and Macarthur regions of New South Wales, Australia.
The Kedumba Creek rises on the eastern side of Walford Park, Katoomba and flows generally south over the Katoomba Cascades, Katoomba Falls, and off the Blue Mountains Range, becoming the Kedumba River below the Three Sisters flowing through the Jamison and Kedumba valleys within the Blue Mountains National Park, before reaching its confluence with the Coxs River within Lake Burragorang. The river descends over its 20km (10miles) course.[1]
