In 1893, Donnelly's Creek weir and the adjacent Sawpit weir
were built to divert water from tributaries of the Watts River to the Maroondah aqueduct. Donnelly's Creek added four and
a half million gallons per day to the Maroondah system. Sawpit Creek Weir operated until it was decommissioned and partially
dismantled in 1988.
DONNELLEY'S CREEK WEIR
It is constructed on Donnelly's Creek and is about 1 metre high, 750mm thick and 15 metres long. It is built of bluestone
and concrete with a metal gate section in the centre. The control wheel for the take-off valve is at the western end of the
weir. A picnic area has been established and visitor facilities include toilets, picnic tables, barbeques and car park.
The Weir remains part of Melbourne Water's distribution system.
Outflow is via an undergrouind pipe which connects to the Maroondah Aqueduct.
