The Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) – Parry Sound District is advising area residents that a Watershed Conditions Statement – Water Safety is in effect until Thursday July 22, 2021. This message will affect residents within the NDMNRF Parry Sound District which includes Muskoka, the Territorial District of Parry Sound and a north-west portion in the County of Haliburton.High water levels and flows are anticipated to remain over the next week as runoff from recent rain moves through the river systems.
Residents are reminded to keep a close watch on conditions and regularly check for updated
messages. With recent rainfall the banks and shorelines adjacent to water bodies can be extremely slippery and unstable. Residents and visitors should exercise caution while around waterbodies 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.
The weather forecast from Environment Canada is calling for 15mm to 25mm today with
thunderstorms possible. The forecast over the weekend and into early next week is for 40% change of showers on Saturday with sun and cloud and seasonal temperatures for Friday, Monday and Tuesday. Description of Current Conditions.
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 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.
