摘要：	The Rock Island Engineer District recently released the draft Project Implementation Report with Integrated Supple-mental Environmental Assessment for a Fish Passage Improve-ment Project at Lock and Dam 22 near Saverton, Mo. The pub-lic review period closed June 19.The project, which is authorized as part of the Navigation and Ecosystem Sustainability Program (NESP), would restore a migration pathway for fish by constructing a "fishway" across the spillway at Lock and Dam 22. If completed, the project would be the first of its kind on the Upper Mississippi River and would increase access to upstream habitats and help improve the size and distribution of native migratory fish populations."The need for fish passage on the Upper Mississippi River has been known by fisheries biologists for over a century," said Mark Cornish, environmental planning section chief for the U.S.Army Corps of Engineers, Regional Planning and Environmen-tal Division, North. "Only recently have methods been identi-fied that can work with the kinds of fish in the Mississippi River."Through a collaborative process, started by the interagency work group known as the Navigation Environmental Coordinat-ing Committee, Lock and Dam 22 was selected as an ideal site to study how to build and operate the first fishway on the Mis-sissippi River.
