Haliburton and Northern Areas
Parks Canada reports after a wetter than normal April in the Haliburton area, with 100-125 mm of rain falling versus the monthly average of 76 mm, the Haliburton area received significant rainfall during the first week of May totalling a further 100-125 mm.

Subsequently the Gull and Burnt River Reservoir Lakes are full or overfull. Gull and Burnt River flows will continue to increase and lakes will continue to rise. There will be reduced inflows today at Twelve Mile and Horseshoe Dam. Central Lakes are full or overfull.
Kawartha Lakes and the Otonabee River
The Kawartha Lakes levels are overfull and will continue to increase due to the high flows from the Gull and Burnt rivers. The Otonabee River flow will continue to increase.
Rice Lake and the Lower Trent
Rice Lake is overfull and will continue to rise due to increased flow on the Otonabee. Lower Trent will increase as well.
The Black River flow has peaked. Water levels and flows are high on the Severn River and will remain high as water will be released from Lake Simcoe as Black River flows decline. Dam operations are complete at Lake St. John to prevent backflow.
The weather forecast suggests that there will be no significant amounts of rain this week.
