The Blue Lake is drained by the west branch of the Sabine River, which is part of the Buller River system. It is fed by a short upper segment of the Sabine, which in turn is fed by underground seepage through the landslide debris impounding the much larger Lake Constance. Blue Lake is roughly boomerang shaped, running north then northwest, with each arm of the lake stretching some 200 metres (700 ft). Its waters are cold, ranging from 5 to 8 °C (41 to 46 °F)
