Melton Reservoir (also known as Exford Weir) is located on the Werribee River approximately 6kms south of Melton.

VicRoad Reference - Map 97 G4.

The Melton recreational area is open from 8.30am to 4.30pm daily.
Recreational facilities

Boating is not permitted upstream of the railway bridge for safety reasons. The water here is shallow and has numerous submerged snags including trees and fencing. Passive recreation, including walking and fishing, is encouraged.

Downstream of the railway bridge, boating is restricted to members of the Melbourne Runabout and Speed Boat Club, which has strict controls to ensure safe boating on such a narrow water body. There is no other boating access in this area because of the steep banks and abutment to private land.

All of our recreational facilities including Melton Reservoir have a carry in out policy, meaning any litter you bring to the recreational reserve must be taken home with you.

Camping, firearms and horses are not permitted. Dogs must be on leads at all times.

Please check if there are any current Blue Green Algae warnings before planning any visits.
The Melton Reservoir is the main regulation storage for the Werribee Irrigation District.

It forms part of a three stage storage system in the Werribee basin. If necessary, water in Pykes Creek and Merrimu storages can be released for storage at Melton before distribution to the Werribee Irrigation District.

Releases from Melton flow into the Werribee River, and irrigation supplies are then diverted into the Werribee Irrigation District via a weir located north of the Werribee township.

The reservoir was initially constructed between 1913 and 1916 to store 21,000 megalitres (ML) of water for irrigation at Werribee. The embankment was raised in 1937 and vertical lift spillway gates were installed. This increased the capacity to 23,500 ML. Since then siltation has reduced its total volume back to 14,340 ML.

Major upgrade works were undertaken from 1988 to 1994 to allow the dam to pass the Probable Maximum Flood (PMF). The primary spillway was remodelled with the removal of the flood gates, construction of a fixed crest, and the spillway chute deepened. As this spillway could only pass about 20% of the PMF, a secondary spillway was required. As a result the main embankment had its crest capped in concrete and concrete steps were provided on the downstream face to enable it to act as a secondary spillway.

Capacity   14,364 ML    
Dead storage   141 ML    
Surface area   230 ha    
Full supply level   82.56 m AHD    
Catchment area   1,114 km2    
Maximum height   35.4 m    
Length   181 m    
Crest length   130 m    
Discharge capacity *   147,000 ML per day    
Crest length   181 m    
Discharge capacity   60,000 ML per day    

* Melton Dam was upgraded to withstand overtopping in 1994. The secondary spillway is the dam embankment itself.
