The county road into Bay Creek Lake (aka Millstone Lake) has been washed out and is closed. 

Bay Creek Lake

Bay Creek Lake, also known as Millstone Lake is about 96 acres and fed by Bay Creek.  Bay Creek is known for its clear clean spring-fed waters. This lake is becoming more popular, but it is not easily found and there are no directional signs from the main highway. 

The lake lies north of State Hwy 147 near the small town of Simpson, IL.  Access is by gravel and dirt roads and then a short portage of your canoe or kayak is necessary to reach the lake. 

However the clear clean waters of Bay Creek Lake make it worth the trip to relax and enjoy the seclusion of this 96-acre lake.
