The Watts River rises below Mount Vinegar in the Yarra Ranges, a part of the Great Dividing Range, within the Watts River Reference Area, near the settlement of Somers Park, north-east of Healesville.

[4] After flowing over the dam spillway, the river flows generally west by south, joined by Meyers Creek,[5] before reaching its confluence with the Yarra River south of Healesville.

[3] Watts River became part of Melbourne's water supply system in 1891, with the construction of a diversion weir and the Maroondah Aqueduct.

[3] In the Aboriginal Woiwurrung language, the name of the river is Broong-ku-galk, with galk meaning "timber" or "sticks".
