Real-Time Water Levels Available on Muskoka GeoHub Web Mapping Portal

While spring brings the promise of warmer weather and longer days, it also brings a variety of conditions, including heavy rain, severe weather, and rapid snowmelt that can increase the risk of flooding in flood-prone areas.

This spring thaw, commonly known as the spring freshet, is a result of snow and ice moving and melting into our lake and river systems, which can last for weeks as the snowpack melts. Residents can prepare for the spring freshet by creating an emergency plan, preparing your property, putting together a 72-hour kit in case of emergency, and monitoring water levels in Muskoka.

“When it comes to emergency preparedness, we all have a role to play” shares Jeff McWilliam, Chief of Paramedic Services and Emergency Planning with the District of Muskoka. “No one knows your property better than you. Assess the risks in and around your property and make a plan. Prepare an emergency kit that will last you and your family at least 72 hours and be sure to include items such as water, food, medications, and supplies for your pet if you have one. Don’t forget to also subscribe to your town or township news page online for flood updates right to your inbox”.
