Water Management Update
Water levels on lakes continue to rise, as we head into the late spring season and opening of navigation on the Trent-Severn Waterway.
The Kawartha Lakes are full at navigation levels. This allows the increase of flows through dams south of Peterborough, though these flows remain below average.
The Haliburton reservoir lakes and Lake Simcoe are below summer levels, but increasing with the spring rains.
Parks Canada teams remain vigilant in their water management responsibilities as preparations are made to open the Trent-Severn Waterway for navigation on May 15th for the 96th consecutive year.

Water Management Update
The spring freshet continues. Snowpack in the Haliburton area has now "fully matured", meaning the composition has changed to ice crystals as it does late in the season, and is melting.

Water Management Update
This spring has been characterized so far by its late arrival and cooler temperatures. Water levels in lakes have been below average levels when, in other years, lakes would already be rising significantly. However, the spring freshet is now underway: snowpack across the watersheds has begun to melt and lakes across the system are rising as a result. Rainfall will allow this trend to continue.

Water Management Update 
The snow pack that remains across the southern portions of the watersheds has "fully matured", meaning the composition has changed to ice crystals as it does late in the season. This process has not yet happened in the snow present in the northern areas of the Trent-Severn watersheds.

Water Management Update
This winter, severe cold, leading to thicker ice, and a lack of mid-winter snow melt throughout Ontario contributed to below average water levels along Ontario Waterway systems and lake and river flows continue to be lower than usual for this time of year.
