Advisories

April 14, 2026 - Reservoirs under Flood Warning 
All reservoirs are expected to fill or overfill this week with at least another 30mm of rainfall expected. Double digit temperatures will increase snowmelt.
Haliburton Area: The remaining snowpack and lake ice are melting quickly and adding to the flows from significant rainfall. All lakes are expected to go above their normal full level in the next week. TSW's work on mitigating risk through Minden means upstream lakes will likely feel a bigger impact.
Burnt River: There is still some snow that is melting fast along with the significant rainfall. The Burnt River is high and passing as much flow as possible. All lakes are expected to go above full if the forecast holds.
Central Lakes: The snow is gone so TSW is only dealing with rainfall. Levels are being managed but expected to exceed full within a few days.
The TSW water management team is monitoring the situation and making whatever adjustments are possible to minimize damaging conditions.
Be attentive. Check on low-lying properties. Secure waterfront infrastructure and assets. Follow the advice of whichever agency represents your area eg. MNRF, Conservation Authorities and local government.
CEWF will continue to work closely with TSW and other agencies to ensure accurate and up-to-date information in the coming days.
