About Sullivans Dam
Sullivans Dam was built to expand Dunedin’s municipal water supply to hill suburbs. Construction began in May 1913 and the reservoir officially opened on 15 July 1916. The dam sits in a forested catchment protected from livestock, preserving water quality while supporting recreational use.
The reservoir holds both stocked rainbow trout and a population of brown trout. Calm waters and surrounding bush create a tranquil fishing environment. The site remains an active part of the city’s water infrastructure while offering public access for outdoor activities.
Native bush and some pine forest surround the water. Grassy areas near the dam provide space for picnics. The location’s dual role as a working reservoir and recreational spot adds historical and environmental interest for visitors.
Trout Fishing
Anglers target rainbow trout that are regularly stocked and brown trout that enter via a pipe. The daily bag limit is one fish. Bait fishing is not permitted due to public health rules. Focus on deeper water at the southern end or weedy shallows near the inflow. Early morning and evening sessions often produce the best results. Always check current Otago Fish & Game regulations before visiting.
Walking and Hiking
The Cloud Forests of Leith Track begins at the northern end of the dam and winds through native bush toward Leith Saddle. The track connects with the Escarpment Track and other routes in the Dunedin Skyline Walk network. Short loops around the reservoir suit casual walkers, while longer options lead to lookouts with city views. Parking is available on Leith Valley Road near the dam wall.
History and Construction
City Councillor Archibald J. Sullivan proposed the dam in 1909 to improve supply for growing suburbs. Work started in May 1913 despite labour shortages during World War I. The completed structure opened on 15 July 1916 and continues to contribute to Dunedin’s water network. Its engineering reflects early twentieth-century infrastructure planning in a challenging forested valley.
What Visitors Often Say
Anglers appreciate the calm setting and stocked trout but note the strict one-fish limit and no-bait rule. Walkers enjoy the short bush tracks and peaceful atmosphere around the water.
Many visitors describe the dam as a convenient half-day outing from Dunedin with easy parking and scenic forest surroundings. Some mention arriving early to secure a spot on busy weekends.
