Blowering Reservoir is a large impoundment on the Tumut River located a short drive south of Tumut in the Snowy Valleys region of New South Wales. At 1,628,000 megalitres — roughly three times the volume of Sydney Harbour — it is one of the largest dams in NSW. The reservoir was created as part of the Snowy Mountains Hydro-Electric Scheme and stores water released from upstream for electricity generation and irrigation in the Murrumbidgee Irrigation Area. The dam wall itself is 747 metres long and 114 metres high, giving a sense of the scale of the impoundment.

For paddlers, the reservoir offers over 70 kilometres of water when combined with nearby Talbingo Dam, making it a substantial destination for canoeing and kayaking. The foreshore is fringed by rugged bushland associated with Kosciuszko National Park, and the surrounding landscape includes forested hillsides and valley views. The Blowering Falls walking track climbs the hillsides above the reservoir and provides changing views of the water from above.

Several boat ramps are available at camping grounds around the lake foreshore, providing multiple access points. Paddlers should be aware that the reservoir is also heavily used by motorised watercraft including water-skiers and jet skis, which is a significant consideration for trip planning. Safety guidance at the site specifically calls out wearing a life jacket, supervising children, watching for underwater hazards, and maintaining safe distances from other vessels.

The dam is stocked with Murray cod, golden perch, silver perch, and also holds brown and rainbow trout, redfin, catfish, river blackfish, and Macquarie perch. The dam and its tributaries are closed to trout fishing between the June and October long weekends, a regulation that may affect paddlers who fish. Camping facilities are available around the foreshore, supporting multi-day trips. Entry to the dam area is free and the site is open 24 hours.
