Water Levels And River Flows Remain Higher Than Normal This Time Of Year

0
The Ministry of Natural Resources and Forestry ā€“ Bracebridge Minden Parry Sound District is advising area residents that a Watershed Conditions Statement ā€“ Water Safety Bulletin is
in effect in the district until Thursday, May 18, 2023. This message will affect residents within the MNRF Bracebridge Minden Parry Sound District for portions of the District of Parry Sound, District of Muskoka and City of Kawartha Lakes within the Black River, Burnt
River, Magnetawan River, and Muskoka River Watersheds.


Boaters are advised to be cautious if traveling on local waterways. Boat traffic during high water conditions can cause damage to shorelines and to shoreline property with vessel wakes.

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.
Lowerlying portions of known floodprone areas may still be impacted to various degrees as lake/river levels as anticipated to remain high for the next several days.

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

Residents that have been affected by high water and flow conditions in the past should continue take necessary action to protect/secure any vulnerable property in proximity to rivers and lakes and closely monitor developing conditions and regularly check for updated
messages.

The ministry is closely monitoring the weather and developing watershed conditions.

Further updates will be issued as appropriate.


Description of Weather System

Runoff from significant rainfall that the area received on April 28 through May 2, 2023, has decreased over the past several days.

Weather forecasts call for seasonal to above seasonal temperatures with minimal rainfall over the next 14days.

Description of Current Conditions
Lake water levels are generally within their normal ranges with the exception of a few locations within the Muskoka River watershed where water levels remain higher than normal for this time of year. Where water levels are currently higher than normal it is anticipated they will decline over the next several days.

The watersheds are cascading systems each waterbody feeds into the next downstream.

Runoff from rain and snowmelt cascades and compounds through the entire system affecting water levels in each waterbody. It will take a number of days for the remaining high flows to work its way through the entire systems. Downstream water bodies may
experience a delay in the full impact of the upstream inputs.

MNRF is closely monitoring the weather and developing watershed conditions.

Further updates will be issued as appropriate.
