www.umesc.usgs.gov — The Upper Mississippi River System has been highly modified for human use since the late 1800s. One effect of these modifications is that many side channels and backwaters are slowly filling with sediment. The Finger Lakes area of the Upper Mississippi River is a system of six connected backwater lakes just below Dam 4 near Kellogg, Minnesota. More... The Upper Mississippi River System has been highly modified for human use since the late 1800s. One effect of these modifications is that many side channels and backwaters are slowly filling with sediment. The Finger Lakes area of the Upper Mississippi River is a system of six connected backwater lakes just below Dam 4 near Kellogg, Minnesota. Most of these lakes receive little flow from the main channel except during floods. Many lakes experience periods of low dissolved oxygen levels especially during winter. The purpose of this study is to determine the flow rates that produce optimal habitat for fish, primarily in winter, with the goal of increasing fish populations. Less...
