From the Lake of the Woods Control Board: Precipitation for the past two months has been the lowest for this time of year since the 1980s in the Lac Seul and Lake of the Woods basins. Refill of both Lake of the Woods and Lac Seul has therefore been mostly due to snow melt and the very high groundwater that persisted since last fall?s extreme rainfall. These flows are now declining with the lack of precipitation and refill has stalled. The Board directed flow reductions from both lakes in late April and early May. Although May and June are typically the wettest months of the year in the basin, lake and river levels will remain lower than normal unless average or greater precipitation occurs over the next few weeks. With the current outflow rates, the Board aims to maintain storage and ensure supply for river flows later in the summer if dry conditions continue. Most current weather forecasts (up to 16 days) have below normal precipitation across the basin. LOWDSA NOTE: June 7th received 53.4 mm (2.1inches) of rain with much more on June 8th overnight (data not yet listed at publishing). There's more on the way with forecasted thunderstorms and rain this evening. - Environment Canada |

The current level of Lac Seul is 355.28 m (1165.6 ft), a 20th percentile level for this time of year. The average lake level increased by 9.5 cm (3.5 in) over the past week and is expected to increase by 9 to 15 cm (3.5 to 6 in) over the next week. Lac Seul authorized outflow is 100 m³/s with no scheduled changes. |
