The North Lake Lonsdale Boat Ramp is located off Sandbar Road at Lake Lonsdale, a large shallow reservoir on Mt William Creek situated about 20 minutes north-west of Stawell in Victoria.

The ramp is protected by a rock wall that provides shelter from south-west winds and associated wave action. In 2022, a second concrete lane was added to the ramp, doubling its capacity at busy times.

Rock beaching alongside the ramp was also installed to help control erosion. The project was funded through the Better Boating Fund and delivered by Grampians Wimmera Mallee Water.

Lake Lonsdale supports a range of on-water activities on its northern side, including boating, water skiing, and fishing, with redfin among the species targeted by anglers.
