The flood warning has been extended to Friday in the North Bay District.
The Ministry of Natural Resources and Forestry says the Sturgeon River, Lake Nipissing and the French River areas were all hit with a significant amount of rain last week forcing existing water levels even higher.
Lake Nipissing has been rising at the rate of two centimetres a day.
The MNRF says Lake Nipissing is now well above damage level height.
All area water bodies are seeing increased water levels including the Montreal River Watershed area, the Ottawa River, Lake Temiskaming and Lake Temagami.
The MNRF says road closures remain in effect in much of the North Bay District and homeowners continue to look to sandbags to help protect their homes as water levels continue to rise.
