The Ministry of Natural Resources – Parry Sound District is advising area residents that a Flood Warning remains in effect.

Residents within the Parry Sound-Muskoka area are advised that some additional or prolonged flooding will occur within known flood-prone areas of many rivers and lakes. Recent warm air temperatures and rainfall has now accelerated the melting rate of the remaining snow pack with an increased runoff into local waterbodies. High water levels or flooding will occur over the next 24-48 hours within Lake Muskoka and the Moon River as part of the lower Muskoka River sub-watershed.

Residents are advised to keep a close watch on conditions, regularly check for updated messages and exercise caution around rivers and lakes as high water levels and flows continue. There is the potential for higher water levels and flows than what is currently being experienced.Residents may wish to take action to protect property in flood-prone or vulnerable areas. MNR is closely monitoring the weather and developing watershed conditions. Further updates to this Flood Warning will be issued as appropriate.
