2010 Water Levels
Conditions were looking drought-like in the spring of 2010. In fact, Manitoba Hydro received calls early in the summer from lake users who wanted the lake level to be increased.
Over the summer, however, precipitation was heavy and inflows into Lake Winnipeg increased dramatically.
Manitoba Hydro's control facility at Jenpeg has been at maximum discharge since July 1. Lake levels would have been up to 60 cm (2 feet) higher going into the October storm, but Jenpeg discharged an extra 30 to 50 per cent over the summer.
Despite the increased outflow capacity, Lake Winnipeg is about 48 cm (1.6 feet) above the long-term average for this time of year simply because more precipitation fell and flowed into the lake than could flow out of it.
