Conditions throughout the basin are slowly improving as the extremely wet conditions seen in April and May are being replaced with drier conditions so far in June. Precipitation since the beginning of the month has remained at or below average for all areas of the basin. The map and table shown below indicate that total basin mean precipitation amounts for the first two weeks of June were less than 10 mm (0.5 in) for most of the basin and no more than 25 mm (1 inch) for northern portions of the basin. These amounts correspond to a range of 17th to 32nd percentile, which is less than normal.

These much drier conditions have caused all tributary flows to drop significantly and most are now approaching high normal levels for this time of year. With less water in the system, all major lake inflows have also peaked and are steadily trending downward. As lake inflows are approaching lake outflows, the rise in lake levels are also gradually decreasing.

In the short term, these decreases in flows and levels are highly dependent on continued dry conditions with even moderate rainfall pausing the return to normal conditions. As the basin continues to drain and tributary conditions return to normal, the lake levels will follow suit and continue to drop. This process will take many weeks and high lake levels for the major lakes and rivers are expected to continue throughout July and into August.

The current level of Lake of the Woods is 324.05 m (1063.1 ft), over 95th percentile level for this time of year. The average lake level rose by 6.5 cm (2 in) over the past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open and no additional actions can be taken to limit lake level rise.

The level of Lake of the Woods is expected to remain quite stable over the next 7 days with a decrease of less than 1 cm (0.5 in) or an increase of up to 2 cm (1 in), depending on the rainfall received across the region. Should weather be favourable, the lake level may be near a peak. However, a return to normal summer levels will likely take many weeks. A return to wet weather could result in a second, higher peak.

As the lake gradually stabilizes, the outflow from the lake will change little. This should result in the level of the Winnipeg River between Kenora and Minaki to also stabilize, with any local precipitation adding temporarily to levels in this stretch of the river. The Winnipeg River level rise over the next 7 days below Norman Dam is expected to be no more than 1-2 cm (0.5 in) with less rise further downstream from Kenora, reaching less than 1 cm (0.5 in) at Minaki. 

The current level of Lac Seul is 356.83 m (1170.7 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 6 cm (2.5 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.

The current level of Lake of the Woods is 324.03 m (1063.1 ft), over 95th percentile level for this time of year. The average lake level rose by 6 cm (2.5 in) over the past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open and no additional actions can be taken to limit lake level rise.

The level of Lake of the Woods is expected to rise by approximately 5-8 cm (2-3 in) over the next 7 days, depending on the rainfall received across the region. Should weather be favourable, a peak may be reached by the end of June followed by a gradual drop. However, a return to normal summer levels will likely take many weeks and will be delayed should there be a return to wet weather.

As the lake continues to rise, the outflow from the lake will very gradually rise. This should result in the level of the Winnipeg River between Kenora and Minaki also gradually rising, with any local precipitation adding temporarily to levels in this stretch of the river. The Winnipeg River level rise over the next 7 days below Norman Dam expected to be 3-6 cm (1-2 in) with less rise further downstream from Kenora, reaching 1-2 cm (1 in) at Minaki. 

The current level of Lac Seul is 356.82 m (1170.7 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 7 cm (3 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.

The current level of Lake of the Woods is 324.01 m (1063.0 ft), over 95th percentile level for this time of year. The average lake level rose by 7 cm (3 in) over the past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open and no additional actions can be taken to limit lake level rise.

The level of Lake of the Woods is expected to rise by approximately 3-7 cm (1-3 in) over the next 7 days, depending on the rainfall received across the region. Should weather be favourable, a peak may be reached by the third week of June followed by a gradual drop. However, a return to normal summer levels will likely take many weeks and will be delayed should there be a return to wet weather.

As the lake continues to rise, the outflow from the lake will very gradually rise. This should result in the level of the Winnipeg River between Kenora and Minaki also gradually rising, with any local precipitation adding temporarily to levels in this stretch of the river. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 1-2 cm (1 in).  Outflow from the Whitedog dam is expected to increase very gradually as it passes the water coming from the Norman dam, plus any local inflows.

The current level of Lac Seul is 356.80 m (1170.6 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 8 cm (3 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.

The main body of Lac Seul is expected to either drop by 1 cm (1/2 in) or rise by 2.5 cm (1 in) over the next 7 days depending on the amount of rainfall received.

Flows and levels on the English River downstream of Lac Seul, including the level at Grassy Narrows, are expected to continue declining as local tributary flows continue to fall.  The level of the Winnipeg River at Boundary Falls is expected to continue dropping over the coming week.

The rate of level decline on the lakes and rivers could slow if the region experiences higher than expected rainfall over the coming week.  However, the overall declining trends are not expected to change over the next week.

The current level of Lake of the Woods is 323.99 m (1063.0 ft), over 95th percentile level for this time of year. The average lake level rose by 8 cm (3 in) over the past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open and no additional actions can be taken to limit lake level rise.

The level of Lake of the Woods is expected to rise by approximately 6-10 cm (2-4 in) over the next 7 days, depending on the rainfall received across the region. Should weather be favourable, a peak may be reached by mid-June followed by a gradual drop. However, a return to normal summer levels will likely take many weeks and will be delayed should there be a return to wet weather.

As the lake continues to rise, the outflow from the lake will very gradually rise. This should result in the level of the Winnipeg River between Kenora and Minaki also gradually rising, with any local precipitation adding temporarily to levels in this stretch of the river. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 1-2 cm (1 in).  Outflow from the Whitedog dam is expected to increase very gradually as it passes the water coming from the Norman dam, plus any local inflows.

The current level of Lac Seul is 356.78 m (1170.5 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 12 cm (5 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.

The main body of Lac Seul is expected to rise by 2-6 cm (1-2 in) over the next 7 days with the rate of rise continuing to slow if drier weather persists through the forecast period.

Flows and levels on the English River downstream of Lac Seul are expected to remain steady or continue declining as local tributaries have been declining over the past week.  The level of the English River at Grassy Narrows  is expected to continue dropping over the coming week if the drier weather persists through the forecast period.

The level of the Winnipeg River at Boundary Falls  is expected to continue dropping over the coming week if the drier weather persists through the forecast period.

The current level of Lake of the Woods is 323.97 m (1062.9 ft), over 95th percentile level for this time of year. The average lake level rose by 11 cm (4 in) over the past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open and no additional actions can be taken to limit lake level rise.

The level of Lake of the Woods is expected to rise by approximately 5-7 cm (2-3 in) over the next 7 days, depending on the rainfall received across the region.

The current level of Lac Seul is 356.76 m (1170.5 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 13 cm (5 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.

The main body of Lac Seul is expected to rise by 4-6 cm (2-3 in) over the next 7 days with the rate of rise continuing to slow if drier weather persists through the forecast period.

Flows and levels on the English River downstream of Lac Seul are expected to remain steady or begin declining as local tributaries have been declining over the last several days.  The level of the English River at Grassy Narrows appears to have peaked and is beginning to decline.  This trend is expected to continue over the coming week if the drier weather persists through the forecast period.

The level of the Winnipeg River at Boundary Falls near the Manitoba border appears to have peaked and is beginning to decline.  This trend is expected to continue over the coming week if the drier weather persists through the forecast period.

The current level of Lake of the Woods is 323.93 m (1062.8 ft), over 95th percentile level for this time of year. The average lake level rose by 11 cm (4 in) over past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950.

The main body of Lac Seul is expected to rise by 9-12 cm (4-5 in) over the next 7 days with the rate of rise slowing if drier weather lasts through the forecast period. The level at Hudson appear to be cresting and may begin to decline if the drier weather continues.

Manitoba Hydro has provided the following forecast information for the Winnipeg River in Manitoba.

Record precipitation over the past two months has been observed in all sub-watershed regions except for Lac La Croix and Rainy-Namakan, where 2014 was slightly greater. The inflows to these lakes, however, have been much higher in 2022 due to the later snowmelt in April and continued above-normal precipitation almost every week for the past two months.

This precipitation has led to the development of record flows in most areas of the entire Winnipeg River drainage basin in Ontario, Manitoba and Minnesota. In addition to damages such as road and bridge washouts in many areas, damage to shorelines and shoreline structures is occurring across the region on both small and large rivers and lakes. Many communities have declared states of emergency with homes, businesses, and community infrastructure such as sewage treatment plants at risk. This is a full regional flooding event that is without precedent on record, and beyond the capacity of any dams in the system to manage. Many water level gauges across the region have reported new records for lake and river water levels and river flows.

Total inflow from April 1-May 31 set a new record for all of the major lakes in the Winnipeg River drainage basin (Namakan Lake, Rainy Lake, Lake of the Woods and Lac Seul).

Rainfall over the past several days once again saw a rise in tributary flows in many areas.

This added water will further delay a return to normal water levels, which could be many weeks out for most areas of the watershed.

The current level of Lake of the Woods is 323.89 m (1062.6 ft), over 95th percentile level for this time of year. The average lake level rose by 10 cm (4 in) over past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950.

The level of Lake of the Woods is expected to rise by approximately 9-12 cm (4-5 in) over the next 7 days, the rate depending on the rainfall received across the region. With drier weather the rate of rise should slow, but timing of the peak will depend on rainfall this month. Lake of the Woods water levels will likely remain above the Legislated Operating Range for many weeks. Record lake levels are possible and will depend on rainfall across the watershed in the next couple of weeks.

As the lake continues to rise, the outflow from the lake will very gradually rise. This should result in the level of the Winnipeg River between Kenora and Minaki also gradually rising, with any local precipitation adding temporarily to levels in this stretch of the river. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 2-4 cm (1-2 in).

The current level of Lac Seul is 356.64 m (1170.1 ft), over 95th percentile level for this time of year. Lac Seul inflow is very high, resulting in a rise of 17 cm (7 in) over the past week. The lake is nearing the Flood Reserve, a range of water levels above the normal operating range defined by federal Order-in-Council that corresponds to a key level for dam safety concern for the Ear Falls dam. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled. The outflow has risen in recent days with lake level rise, but will be reduced to 800 m³/s on June 2.

The main body of Lac Seul is expected to rise by 11-14 cm (4-6 in) over the next 7 days with the rate of rise slowing if drier weather lasts through the forecast period.

Extremely high flow conditions are occurring across many areas of the Winnipeg River drainage basin in Ontario, Manitoba and Minnesota following record high precipitation since the start of April and early May. While flows in most natural rivers in the basin are dropping, many remain above previous all-time records. Forecasts indicate that inflows to all major lakes will rise for 2-3 days in response to the early week precipitation before falling again. Water levels will remain high for at least several weeks across most areas of the drainage basin even with dry conditions. Wet weather will prolong the duration of high water levels.

The current level of Lake of the Woods is 323.85 m (1062.5 ft), over 95th percentile level for this time of year. The average lake level rose by 9 cm (4 in) over past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950.

The level of Lake of the Woods is expected to rise by approximately 15-21 cm (6-8 in) over the next 7 days, the rate depending on the rainfall received on Monday and Tuesday as a series of thunderstorms and showers pass through the region. Continued rise beyond the 7-day forecast window is expected though the rate of rise should slow with drier weather. The timing of the peak cannot be predicted at this point and will depend on rainfall. Lake of the Woods water levels will likely remain above the Legislated Operating Range for many weeks. Record lake levels are possible and will depend on rainfall across the watershed in the next couple of weeks.

As the lake continues to rise, the level of the Winnipeg River between Kenora and Minaki is also expected to rise, though recently the level of Minaki has declined slightly, likely due to local tributary decline. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 2-4 cm (1-2 in). This estimate is approximate given uncertainty in the local flows entering the river from tributary areas and the rainfall on Monday and Tuesday. The river will continue to gradually rise as long as Lake of the Woods continues to rise and daily fluctuations, up or down, are possible depending on how prevailing winds affect the local level of Lake of the Woods above the dams.

The current level of Lac Seul is 356.60 m (1169.9 ft), over 95th percentile level for this time of year. Lac Seul inflow is very high, resulting in a rise of 19 cm (8 in) over the past week. The lake is nearing the Flood Reserve, a range of water levels above the normal operating range defined by federal Order-in-Council that corresponds to a key level for dam safety concern for the Ear Falls dam. To avoid exceeding this range , additional outflow increases took place last weekend, with outflow now at 827m³/s. This is a very high outflow, last reached in 2008. Depending on the rainfall totals early this week, further increases are possible and will be announced on this Notice Board.

The main body of Lac Seul is expected to rise by 15-22 cm (6-9 in) over the next 7 days. Higher or lower rainfall amounts then currently forecast could see a rise outside of this forecast range.

Extremely high flow conditions are occurring across many areas of the Winnipeg River drainage basin in Ontario, Manitoba and Minnesota following record high precipitation since the start of April and early May. While flows in most natural rivers in the basin are dropping, many remain above previous all-time records. Forecasts indicate that inflows to all major lakes will continue to be exceptionally high, but falling, through the weekend until additional rainfall arrives arrives late Sunday into Monday. The response of rivers to this system will depend on rain, how much falls and where. Water levels will remain high for at least several weeks across most areas of the drainage basin even with dry conditions. Wet weather will prolong the duration of high water levels.

The current level of Lake of the Woods is 323.81 m (1062.4 ft), over 95th percentile level for this time of year. The average lake level rose by 11 cm (4 in) over past week. The lake level has risen above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950.

The level of Lake of the Woods is expected to rise by approximately 7-15 cm (3-6 in) over the next 7 days, the rate depending on the rainfall received. Inflow to Lake of the Woods is expected to continue to fall until the rainfall beginning on Sunday, followed by a brief rise, then a return to falling flows. There is the possibility of much higher rainfall over this period, which would cause inflows to rise sharply. Continued rise beyond the 7-day forecast window is expected. The timing of the peak cannot be predicted at this point and will depend on rainfall. Lake of the Woods water levels will likely remain above the Legislated Operating Range for many weeks. Record lake levels are possible and will depend on rainfall across the watershed in the next couple of weeks.

The level of Lake of the Woods is above the top of the Legislated Operating Range, 323.47 m (1061.25 ft). The International Lake of the Woods Control Board has been activated and is working with the Canadian Lake of the Woods Control Board to approve any actions taken with respect to Lake of the Woods. Under Canada-US Treaty, upon reaching a lake level of 323.39 m (1061.0 ft), outflow from the lake must be regulated to avoid exceeding a level of 323.85 m (1062.5 ft). The dams in Kenora have been fully opened since the level of the lake was at an elevation of 323.24 m (1060.5 ft). No additional actions can be taken by the Boards to limit the rate of lake rise, which will depend on rainfall over the coming weeks.

As the lake continues to rise, the level of the Winnipeg River between Kenora and Minaki will also rise. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 2-4 cm (1-2 in). This estimate is approximate given uncertainty in the local flows entering the river from tributary areas and the weekend rainfall. The river will continue to gradually rise as long as Lake of the Woods continues to rise and daily fluctuations, up or down, are possible depending on how prevailing winds affect the local level of Lake of the Woods above the dams.

The current level of Lac Seul is 356.54 m (1169.7 ft), over 95th percentile level for this time of year. Lac Seul inflow is extremely high, resulting in a rise of 37 cm (15 in) over the past week. The lake is nearing the Flood Reserve, a range of water levels above the normal operating range defined by federal Order-in-Council that corresponds to a key level for dam safety concern for the Ear Falls dam. To avoid exceeding this range , additional outflow increases took place last weekend, with outflow now at 802 m³/s. This is a very high outflow, last reached in 2008. An additional outflow increase, to 850 m³/s, that was scheduled for Friday, May 27 was canceled. However, depending on the upcoming rainfall, further increases are possible over the next week and will be announced on this Notice Board.

The main body of Lac Seul is expected to rise by 15-25 cm (6-10 in) over the next 7 days. Higher or lower rainfall amounts then currently forecast could see a rise outside of this forecast range.

The flow increases from Lac Seul that took place last weekend will take some time to work down the English River, with an estimate of about two weeks to reach Nutimik Lake.

Manitoba Hydro has provided the following information on the Winnipeg River through the Whiteshell.
