The current level of Lake of the Woods is 322.66 m (1058.6 ft), a 30th percentile level for this time of year. The average lake level declined by 1 cm (0.5 in) over the past week. With the lake level slightly higher than expected for early December, Lake of the Woods outflow can be increased while still targeting end-of-winter levels set in the Regulation Strategy. Temperatures are also expected to climb above freezing this week and ice has just started forming on the Winnipeg River.
Lake of the Woods authorized outflow will increase to 300 m3/s on Thursday, December 7. This flow increase will cause levels on the Winnipeg River to rise by approximately 5 cm (2 in) downstream of the Norman Dam, 2 cm (1 in) at the Dalles and will cause very little level change at Minaki.
