Summary of 1991 winter water quality characteristics at the Pool 8 Islands Habitat Rehabilitation and Enhancement Project, Upper Mississippi River system
Many islands in the lower portion of Navigation Pool 8 of the Upper Mississippi River System have eroded away since construction of Lock and Dam 8, exposing shallow aquatic areas to increased flow, wave action, and sediment resuspension. Phase I of the Pool 8 Islands Habitat Rehabilitation and Enhancement Project (HREP) was designed to improve habitat for fish and waterflow in an area enclosed by a U-shaped system of islands (Horseshoe Island, river miles 684-688; U.S. Army Corps of Engineers 1989). The Phase I project included closure of inlets at the upstream end of Horseshoe Island in the summer of 1989. Since July 1988, the Wisconsin Field Station of the Long Term Resource Monitoring Program for the Upper Mississippi River System has been monitoring water quality (current velocity, temperature, dissolved oxygen, turbidity, Secchi disk transparency, and specific conductance) at one permanent sampling station enclosd by Horseshoe Island.
