Opie where the lake comes under the railroad tracks, bike trail and hwy 162 is a narrow pinch point that bogs down flow of water headed to horseshoe lake that finally then heads to the Mississippi River.. They are putting a large box culvert to open that up to drain the lake faster. it will not solve all our problems, but it will help get the water from the lake to the river faster. As long lake drains faster, hopefully it can reduce sandbagging
