Restoring an Urban National Park
Buildings from the former 'Bureau of Mines' site were demolished and the Coldwater Spring was re-opened to the public in 2012. The National Park Service, partners and volunteers have been working since to restore the prairie, oak savanna and wetlands surrounding the historic spring house and reservoir.
Monarch caterpillars chomp on the 4 milkweed species planted and seeded (Coldwater Spring Plant List (PDF; 155kb). Amphibians and reptiles, like tiger salamanders and snapping turtles, have been seen feasting on invertebrates in the newly restored wetlands. Eastern bluebirds stop over during spring and fall migration to fill up on insects and water. Ospreys dive-bomb fish living in the springhouse reservoir. Red fox and coyotes prey on small mammals that burrow in the restored prairie. Wildlife, insects, native fish and migrating birds are all signs of a healthier ecosystem at Coldwater Spring.
