Cotter Dam

Cotter Dam, a striking concrete arch structure on the Cotter River, is a surprising oasis just a short drive from Canberra's city centre. Surrounded by bushland and part of the Cotter Reserve, it offers a refreshing escape for swimming, picnicking, and gentle walks. The dam's history dates back to 1915, supplying water to the capital, and today its lookout and visitor area provide a serene spot to appreciate engineering heritage and natural beauty.

Highlights & What to See

• Cotter Dam Lookout: Walk across the dam wall for panoramic views of the reservoir and the valley below. Interpretive signs explain the dam's construction and role in Canberra's water supply.
• Swimming and Picnicking: On hot days, the designated swimming area below the dam is a favourite for locals. Grassy banks and barbecues make it an ideal picnic spot.
• Cotter Reserve Walking Trails: Explore short bushwalks along the river, including the Cotter Loop Track (1.5 km) which offers birdwatching and river glimpses.
• Historic Cotter Precinct: Nearby, the original Cotter River settlement includes a historic bridge and remnants of early infrastructure, adding a layer of cultural interest.

Suggested Time to Spend

Most visitors spend 1–2 hours here, combining a walk across the dam with a swim or picnic. If you're keen on the longer walking trails, allocate half a day. The site is best visited in late morning to enjoy the calm waters before the afternoon crowds arrive, especially on weekends.
