Water management updates

Weather

Rainfall amounts for September and October have contributed to 25-75 % less precipitation compared to the long-term averages. The months of September and October contributed to values that are less than 50-75 mm than the long-term mean. The 5-day forecast suggests a temperature trend above freezing mark and about 3-16 mm of rain.

Outlook

The extended low amounts of precipitation have decreased flows and water levels at most locations. The most recent rain fall events were spatially variable and not significant, as a result currently, flows remain below average and receding across the Trent-Severn Watershed. The current forecast indicates that water levels and outflows may continue to decline and are subject to change depending on amounts of rain in the forecast.

The Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Haliburton and Northern Areas

The extended trend of below-average precipitation has impacted the watersheds across the entire Trent-Severn Waterway, including the reservoir lakes. Most lakes are well below long-term average water levels. Most of the reservoir lakes remain at their respective winter set dam configuration. The Gull River reservoirs are 35% full, and the Burnt River reservoirs are 35% full. The Central Reservoirs are 40% full. The Gull and Burnt River flows are significantly below average.

Kawartha Lakes and the Otonabee River

The Kawartha Lakes are near average and are subject to the gradual seasonal drawdown. The Otonabee River is below average for this time of year.

Rice Lake and the Lower Trent

Rice Lake is slightly above average, and the Lower Trent is currently being sustained by the minimum flows out of the Otonabee River.

Severn River

Lake Simcoe's water levels are below average but on the rule curve and stable. Lake Simcoe outflows remain minimized. Flows on the Black River and Severn River are significantly below average.

Weather

During the last 3 weeks Trent-Severn watersheds have received 50-100% above normal amount of rain. Water levels were generally higher than normal in advance of the forecasted system as not all watersheds have recovered completely from the last significant rain event. As a result of the wide-spread system named Tropical Depression Beryl the watersheds received anywhere 35-75 mm of rain. The impacts from the above average amounts of precipitation received remain across the system. Flows and levels are above normal for this time of the year across all locations.

The Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Haliburton and Northern Areas

Water levels and flows remain high in northern areas. Most lake levels on the Gull River, Burnt River system, and Central Lakes are near full and are increasing. Lake levels are monitored on a 24 hour basis and water management operations are being conducted based on the current watershed conditions, lake levels, estimated runoff amounts and forecasted rainfall. The flows on Burnt River are above average and increasing and are expected to be sustained by the enhanced runoff from precipitation and operations in reservoirs. The flows on the Gull River are significantly above average for this time of year.

Kawartha Lakes and the Otonabee River

Water levels in the Kawartha Lakes are above full level conditions across the system due to sustained and elevated inflows from the Haliburtons areas and the received amounts of rainfall. Flows on the Otonabee River are above average for this time of year. The lake levels and flows are expected to continue rising into the weekend.

Rice Lake and the Lower Trent

Water levels on Rice Lake, Upper and the Lower Trent River are above average for this time of year. The lake levels and flows are expected to continue rising into the weekend.

Severn River

Lake Simcoe water levels are above average, above full, and expected to increase from the received rain amounts. Black River flows are above average and increasing. Lake Simcoe outflows have been increased and will be managed in consideration to Black River flows and Severn River inflows trend. Flows on the Severn River are high and are likely to remain high.

Weather

Over the past 7 days, the watersheds have received 35 - 85 mm of rain which significantly exceeds the normal precipitation for the month of June. The last 25 days have seen precipitation values in excess of 50 % above normal, which has increased water levels and flows across the entire system. The 5-day forecast suggests continued average daytime temperatures with 10-25 mm of rain. Please check the website of your local conservation authority or the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry for the most up-to-date watershed conditions. The weather forecast suggests that there is a risk of further thunderstorms towards the end of the week across the Trent-Severn.

Haliburton and Northern Areas

Due to the recent rain, the Gull, Burnt, and Central Lakes are full to slightly overfull. Flows on the Gull have not peaked and will increase due to adjustments and current levels upstream. The Burnt River is expected to peak within the next 24 hours.

Kawartha Lakes and the Otonabee River

The Kawartha Lakes levels are above average and expected to increase further due to recent rain. The Otonabee River flow is higher than normal and will remain high due to the recent rain.‎

The current forecast indicates that water levels and outflows will recede and remain on average at most locations. The fluctuations in levels vary and highly depend on the amount of snow and any significant changes in temperature forecasts.

The Trent-Severn Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Ice on Shorelines

The temperature variations around the freezing mark makes ice weak along the shoreline, which is then easily broken and moved by windy conditions. The areas subject to the greatest impact are those facing the primary wind direction. In the event of strong wind conditions, the public should be aware of possible onshore ice movement leading to shoreline damage. The current forecast winds are moderate over the next 36 hours, with wind gusts as high as 55 km/hr.

Haliburton and Northern Areas

Most reservoirs have water levels below average for this time of year. The snow pack is present and is near the average for this time of year. Lake levels are monitored daily and assessed in relation to estimated runoff amounts. The flows on Gull and Burnt Rivers are near average and receding.

Weather

The 5-day forecast suggests 15-30 mm of mixed precipitation, with most of the precipitation falling mainly on Thursday night into Friday morning. Air temperatures are expected to drop significantly on Friday afternoon below 0°C across the entire Trent and Severn Watersheds.

Outlook

Flows remain high after the series of recent events that amounted to over 100 mm of mixed precipitation and solid accumulation across the TSW watersheds. The current forecast indicates that water levels and outflows will continue to remain high at most locations. The fluctuations in levels vary and highly depend on the amount of snow remaining and any significant changes in temperature forecasts.

The Trent-Severn Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Hours of Operation

Please note: Station opening and closing times, as well as first and last lockage, are not guaranteed and may be affected by water management duties, maintenance activities or other types of navigation interruptions.

Weather

Over the past 7 days, the watersheds have received 50 - 100 mm of rain which significantly exceeds the normal precipitation for the month of May and early June. The last 25 days have seen precipitation values in excess of 50-75 % above normal, which has increased water levels and flows across the entire system. Please check the website of your local conservation authority or the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry for the most up-to-date watershed conditions. The weather forecast suggests that there is a risk of further thunderstorms towards the end of the week across the Trent-Severn.

Severn River

The Black River has not peaked, but water levels and flows are high on the Severn River and will remain high until water levels decrease on Lake Simcoe and Sparrow Lake. Flows across the navigation channel will increase during the night to reduce levels on the system. The public should consider these overnight flows as non-navigable. Therefore residents are advised to exercise extreme caution if travelling outside Parks Canada’s hours of operation.

Weather

The 14-day forecast suggests a high-temperature trend for the watersheds of the Trent-Severn Waterway system. There is up to 30 mm of rainfall forecasted for the next 5 days. Most of the rainfall forecasted is associated with thunderstorms and could be highly variable from one location to another.

Outlook

The watersheds of the Haliburton reservoirs experienced earlier than normal freshet, which in combination with warmer air temperatures has resulted in the loss of most of the winter snowpack by late March and the recession of runoff by early April. Assuming seasonal average precipitation going forward, the public can expect lake levels to remain near full during the month of May, and seasonal averages through the summer. Currently, flows are below average across the Trent-Severn watersheds.

The Trent-Severn Water Management team will be actively monitoring conditions. All watershed condition updates will be released by your Conservation Authority.

Weather

The weather forecast for next 5 days is predicting a moderate mixed precipitation event of 20 mm combined with plus temperatures approaching 10 degrees and above zero at night.

Outlook

Recent weeks warm temperatures have primed the snow to be ready to run off and current above zero temperature trend resulted in the ongoing snowmelt in the southern watershed. Haliburton snowpack remained stable with no significant losses and tracks close to seasonal averages. Water levels and outflows are expected to remain elevated at all locations due to the precipitation and snow melt. Trent Severn Water Management team will be active and the changing conditions will be closely monitored. Any watershed conditions updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Haliburton and Northern Areas

Most of the reservoir lakes remain at their respective winter set dam configuration. Operational activities in some reservoir lakes are conducted in anticipation of localized melt. Water levels on the lakes in general are well below average and are levelling off and/or slightly increasing. Flows on the Gull and Burnt Rivers remain on average for this time of year and will likely increase with the rainfall and warm temperatures. Current snowpack is measured to vary from above average in some areas to average for this time of the year and is expected to slowly recede with warm temperatures and localized melt.

Kawartha Lakes and the Otonabee River

Water levels on the Kawartha Lakes are well below average, but are expected to level off due to the forecasted rain and ongoing snow melt. Water flows on the Otonabee River are above average for this time of year. Flows will likely remain higher as a result of the mild temperatures and precipitation.

Flows on the Severn River are on average and will continue to increase with additional discharge from Lake Simcoe and additional inflows generated by the mild temperature and rain.

Weather

The weather forecast for early next week is changing significantly from day to day. A 20 to 30 mm of mixed precipitation event is forecasted across next 5 days.

Outlook

Precipitation amounts for September to December 2021 have contributed to 100-125 % more precipitation relative to normal. Rainfall and warm temperatures earlier in the month have generated active snow melt which, in combination with the above normal precipitation amounts, resulted in raising the flows and water levels across the watersheds. With currently forecasted air temperatures below zero, water levels and outflows are expected to crest and slowly recede at all locations. However, there is a measure of uncertainty associated with this. Depending on the exact amounts of precipitation over the next 5 days, whether it falls as rain or snow and whether air temperature is above or below zero, local snow melt and snow melt runoff may occur, impacting the watershed response. Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Ice on shorelines

The temperature variations around and above the freezing mark makes ice weak along the shoreline which is then easily broken and moved by windy conditions.

Weather

Significant rainfall occurred over past 2 days and resulted in total precipitation over that time period of about 60-100 mm which increased water levels and flows across the system. Some rainfall forecast is expected today with a potential accumulation of 10-20 mm and higher in the areas of localized thunderstorm activity.

Outlook

Due to the localized nature of the rain events some areas have received 150% of the normal monthly precipitation in September. The impacts from the above average amounts of precipitation received remain across the system. Flows and levels are above normal for this time of the year across all locations.

Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Weather

The five day weather forecast is predicting a low system which may result in total of 30-40 mm of rain and heavier amounts in localized areas impacted by thunderstorms.

Outlook

During the last 3 weeks Trent-Severn watersheds have received close to 100 mm above normal amount of rain. Due to the localized nature of the rain events some areas have received twice the monthly precipitation. The impacts from the above average amounts of precipitation received remain across the system. Flows and levels are above normal for this time of the year across all locations.

Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Weather

Rainfall amounts for March-May have contributed to 40-55 % less precipitation compared to the long term mean value for spring season. The month of May contributed to values that are less than 50-75 mm than the long term mean. The 5 day forecast suggests 15-25 mm of rain and above 20 C day time air temperatures. Most of the rainfall forecasted is associated with thunderstorms and could be highly variable from one location to another.

Outlook

The spring of 2021 has presented a unique set of challenges for the water management program of the Waterway. The early melt and exceedingly dry conditions resulted in the minimal flows experienced since early April until present across the system and the low levels in all flow-through lakes. The dry conditions resulted in additional strain on some of the Haliburton Reservoirs more than others. Every effort is made to ensure that water management decisions are carefully considered, acknowledging Parks Canada’s responsibility to balance the needs of all users in the system.

Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Operations for Lake St. John in preparation for increased flows on the Black River are complete. Water levels and flows are expected to increase everywhere on the Severn River.

Weather

The 7-day forecast is indicating temperatures close to zero degrees Celsius and low precipitation amount. This week's weather event resulted in a small precipitation event of 5 mm combined with temperatures approaching above 10 degrees and above zero at night. The warm-up and cool-down period was estimated to be approximately 36 hours in length. The brief warm spell is followed by more seasonal temperatures.

Outlook

Rainfall and warm temperatures have, for the most part, primed the snow to be ready to run off and also resulted in the ongoing snowmelt in the southern watershed. Water levels and outflows are expected to remain elevated at all locations due to the precipitation and snowmelt.

Weather

The 7 day forecast is indicating temperatures above zero degrees Celsius and a low precipitation amount of approximately 5 mm.

Outlook

The watersheds of the Haliburton reservoirs experienced earlier than normal freshet, which in combination with warmer air temperatures has resulted in the loss of the most winter snowpack during late March and melt runoff recession in early April. Given the normal amount of April precipitation, the public can expect the current lake levels to gradually rise during the month of May, achieving seasonal averages heading into summer. Currently, flows are close to average and receding across the Trent-Severn Watershed.

Haliburton and Northern Areas

In general, water levels in the Haliburton Reservoirs are below average. The Gull River flows are slightly above average. The Burnt River flows are below average and receding.

Weather

The 7 day forecast is indicating temperatures close to zero degrees Celsius and mixed precipitation amount of approximately 10 mm.

Outlook

The watersheds of the Haliburton reservoirs experienced earlier than normal freshet which in combination with warmer air temperatures has resulted in the loss of the most winter snowpack. The melt event generated higher than seasonal inflows and resulted in higher lake levels of the reservoirs. Given the remaining potential for seasonal rains in April and May, the public can expect lake levels to be held to current levels or lower to accommodate precipitation and to mitigate flooding while gradually achieving seasonal averages heading into summer. Currently flows have peaked and receding across the Trent-Severn Watershed. The weather forecast suggests that flows and levels should remain steady.

Ice on Shorelines

The freshet has increased water levels and as a result has moved the ice sheet on most lakes. As the ice sheet is not attached at the shoreline it can be moved by windy conditions. The areas subject to the greatest potential ice impact are those facing the primary wind direction. In the event of strong wind conditions the public should be aware of possible onshore ice movement leading to shoreline damage.

This weather resulted in high inflows which have increased water levels on lakes and river reaches. The weather forecast suggests that elevated flows and levels should remain steady.

Ice on Shorelines

The recent precipitation event has increased water levels and as a result has moved the ice sheet on most lakes. As the ice sheet is not attached at the shoreline it can be moved by windy conditions. The areas subject to the greatest potential ice impact are those facing the primary wind direction. In the event of strong wind conditions the public should be aware of possible onshore ice movement leading to shoreline damage. Also of concern is some of the colder temperatures that are forecasted for beginning of next week. With high outflows on Otonabee and Trent Rivers there is a possibility of the formation of frazil ice and potential ice jams.
