Lake Moawhango is a small lake located with the New Zealand Army's Waiouru Training area. It is fed by tributaries running off the slopes of Mt Ruapehu, and feeds water into the Tongariro River Hydro scheme via the Moawhango Tunnel. The lake is dammed at the southern end.

Lake Moawhango contains a large population of wild rainbow trout, and while these are easily caught, they very rarely exceed 2 lbs in size.
