there was a big thing over them because there was a group of people who wanted to create a lake called Mounds Lake, which was going to destroy parts of Mound's State Park (which is named such after the Earthworks) but environmentalist such as myself went nuts because not only would it destroy the habitat potentially killing them off, It would also flood the Rangeline Nature Preserve, this lake was also gonna sit on two former landfill sites that were packed down and leveled paved with pipes sticking out to vent the gasses the deadly potential of the combination got the other cities that would have been effected to vote with a BIG HELL NO. You wouldn't believe the people who want the lake still. Where we are building if it gets revived we would have lake front property and sell right away and move at least 10 miles outside the city limits.
