Final Environmental Assessment

for Construction of Lost Grove Lake, Scott County, Iowa


The final Environmental Assessment (EA) for the lake construction at Lost Grove Wildlife Management Area (WMA), Scott County, Iowa was approved on June 22, 2004 when the Finding of No Significant Impact (FONSI) was signed.  The Proposed Alternative was selected which will create an impoundment that will cover 350 surface acres. With this alternative the elevation of county road 220th Avenue will be raised to allow continued use by vehicular traffic. Shoulders will be added to the raised portion for safe parking and to permit shore fishing.  A large culvert under the road will provide boats access to the upper end of the lake. Six locations will be developed for public access to the lake.  Boat ramps will be constructed at three of these areas and restrooms present at two. Roads, parking areas and shoreline fishing areas will be developed at all six locations.


The other action alternative would be identical to the "proposed action" except that 220th Avenue would not be raised and would be covered by the impoundment waters.

The project is proposed by the Iowa Department of Natural Resources for funding through the Federal Aid in Sport Fish Restoration Act, administered by the U.S. Fish and Wildlife Service. Projects funded by the Service are required to comply with NEPA and other associated Federal requirements including the Historic Preservation Act and the Endangered Species Act.
