The Lostock Dam Experience

1. Camp

Camping is available at a nearby caravan park with powered and unpowered sites on the banks of the Paterson River just downstream from the dam wall. Facilities include barbecues, picnic shelters, kiosk, showers and toilets. The lake foreshores are perfect for picnics, bushwalking and spotting local wildlife.

2. Water sports

Water sports include sailing, canoeing, kayaking and swimming. A boat ramp is located near the dam wall. There is a speed limit to prevent water skiing and fast power boating on the relatively small lake.

3. Fishing

Facts & History

Lostock Dam is situated on the Paterson River, a major tributary of the Hunter River, about 65 kilometres north of Singleton and about 65 kilometres north-west of Maitland in the NSW Hunter Valley. The dam is about 225 kilometres north-west of Sydney.

Lostock Dam has a capacity of 20,200 megalitres, making it one of the smaller NSW water storages.

The dam is named after the town of Lostock which lies about 2 kilometres downstream.

Why the dam was built

Lostock Dam was built in the early 1970s to provide a reliable supply of water for agriculture in the Paterson Valley following the drought of 1964-66.

Dairying, cattle grazing and vegetables are the main agricultural industries supported by irrigation. Lostock Dam also provides water for town supplies, industry, domestic and stock use along the Paterson River, as well as environmental flows.

The dam’s small 277 square kilometre catchment includes farming country in the upper reaches of the Paterson River, and areas of state forest and national park in the Mount Royal Range.

How the dam was built

Lostock Dam is a rock-fill embankment with a clay core. A concrete-lined flip bucket spillway is located just west of the dam wall. The wall is 701 metres long and 38 metres high.

To prevent water leaking through cracks in the rock foundation of the dam wall, holes up to 27 metres deep were drilled into the foundation and filled with a mixture of cement and water pumped in under pressure.

Construction began in 1969 and finished in 1971.

Later improvements

In 2010 mini hydro-electric power facilities were installed that generate on irrigation and environmental flows.
