The Lake Huron water level is currently only 10 cm below the monthly record high (set in 1986) for September and 76 cm above the long-term September average. The lake level is expected to remain high throughout the fall and winter.
This means there will be a heightened risk of flooding and ice-related issues around the mouth of the Nine Mile River for the next several of months. There are three situations in which flooding can be expected:
- Waves produced by strong northwest winds cause sand to accumulate at the mouth of the river and obstruct river flow
- High river flows following rainfall or snowmelt may carry surface ice down the river causing ice jams to form
- The temperature drops quickly when the river is not frozen. The combination of very cold temperatures and open water may lead to the formation of frazil ice that obstructs river flow.
When these conditions occur, the Apple Lane and Maple Lane areas may flood rapidly. Flooding may impact structures and result in a loss of access to these areas. Given the current level of the lake, it is expected that flood levels will be higher than those experienced earlier this year.
Flooding of the Apple Lane and Maple Lane areas area is expected to be an ongoing issue throughout the winter. Residents should remain prepared for such sporadic events and are reminded that it is dangerous to attempt to drive or walk through flood waters. Children and pets should be kept well away from the flooded area. Residents are encouraged to call 519-357-0890 if they notice that flooding is occurring.
Because of the sporadic nature of these events this message is in effect until January 15, 2021 or until sufficient changes to local conditions warrant further updates.
