270 MM OF RAIN DUMPED ON MUSKOKA PAST 3 WEEKS, SAYS NDMNRF

MUSKOKA — High water levels and flows will continue the next week as runoff from recent rain moves through the river systems.

The weather forecast from Environment Canada is calling for 15mm to 25mm today, Thursday July 15, with thunderstorms possible.

The forecast over the weekend and into early next week is for 40 per cent chance of showers on Saturday with sun and cloud and seasonal temperatures for Friday, Monday and Tuesday

The Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) — Parry Sound District — is advising area residents that the above Watershed Conditions Statement – Water Safety is in effect until next Thursday, July 22.

It will affect those in Muskoka, Parry Sound and part of northwest Haliburton.

Water levels for most lakes are at or above their upper operating range for this time of year. River flows are extremely high for this time of year.

The local watersheds have received approximately 270mm of rain over the past three weeks.

This has caused saturated watershed conditions and significant runoff. Additional rainfall forecasted for today will likely cause water levels and flows to increase slightly and sustain the high water levels and flows for longer.

Minor flooding within flood prone areas is possible or may be occurring.

NDMNRF is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate

Residents are reminded to keep a close watch on conditions and regularly check for updated messages.

They say that with recent rainfall the banks and shorelines adjacent to water bodies can be extremely slippery and unstable.

Residents and visitors are urged to exercise caution while around water bodies and maintain close supervision of children and pets.

Rivers are flowing much faster than usual for this time of year and may be hazardous for recreational activities. Lake levels are currently higher than usual for this time of year possibly causing some challenges for water activities.

NDMNRF also advises extreme caution when using forest access roads for outdoor activities as they may become inundated with water, are prone to washouts and may become impassible due to localized flooding.
