The Water Security Agency says the area from Little Bear Lake to over Creighton has received more than 400 mm of rainfall since April 1st. Over the past three days, it has ranged from 10 to20 mm with higher amounts where thunderstorms occurred, such as near Trade Lake where accumulations of 40 mm were seen. The result of this has been very high flows and lake levels across the Churchill River and Lower Saskatchewan Riven basins. Cumulative rainfall since April 1st is near record. The Agency says high river and lake levels can be expected for the rest of the summer and, in some cases, into the fall and winter. In most areas, flows and water levels have peaked or are expected to peak slightly lower than previous historical highs. However, flows and levels in the Lower Churchill River, including Reindeer River and Churchill River near Sandy Bay, have exceeded previous historical highs.
