Lake Bellfield is a reservoir situated in the eastern Grampians near Halls Gap in Victoria, approximately three hours from Melbourne. The lake receives inflow from Fyans Creek and serves as the primary water source for the Wimmera Mallee Pipeline system, supplying towns including Halls Gap and Pomonal, farms, and environmental wetlands across roughly 10% of Victoria. Its catchment sits within a protected national park, which contributes to generally high water quality.

Paddling is permitted on the lake, with canoes, kayaks, and paddleboards all suitable for use. Powerboats with internal combustion engines are not allowed; however, electric motors are permitted. Fishing from the dam wall is prohibited, and dogs are not permitted at the lake. The boating authority for Lake Bellfield is GWMWater. A boat ramp is available, though at least one visitor has noted it is not particularly well-appointed.

The lake is considered calm water suitable for beginners, and late spring through early autumn is generally regarded as the best period for paddling, when weather is mild and water levels are adequate. The Halls Gap Lakeside Tourist Park is located directly adjacent to the 800-metre dam wall and provides convenient access to the water. Toilets are available at the lake's observation tower and viewing area. Campfires are permitted only in the designated picnic area, subject to Country Fire Authority restrictions.

Wildlife is a notable feature of paddling on Lake Bellfield. Kangaroos are commonly seen at the water's edge, and birdlife including pelicans, herons, and eagles can be spotted while on the water. The lake sits within the Grampians National Park landscape, with the surrounding ranges providing a distinctive backdrop.

Canoe and kayak hire is available through local operators in the Grampians region, including Nelson Boat Hire, so paddlers do not need to bring their own equipment. Guided tours are also offered by operators such as Bright Adventure Company for those seeking instruction or a structured experience. The lake is stocked with fish including brown and rainbow trout, redfin, and salmon, meaning anglers may share the water, particularly during warmer months when recreational use increases.
