The District lies within the river corridor bordered by the steep bluffs of Winona and Houston Counties in Minnesota and Trempealeau, La Crosse, and Vernon Counties in Wisconsin. More than 100,000 people living in the greater La Crosse area are only minutes away from the Refuge. This accessibility is reflected in the amount of use the District receives annually from such users as pleasure boaters, campers, hunters, fishermen, and for wildlife observation. Habitat types include about 15,400 acres of open water, 16,100 acres ofbackwater marshes and sloughs, and 10,450 acres ofbottomland hardwood forests. Extensive tracts of bottomland hardwood forest are interlaced with sloughs, marshes, and beaver ponds where the Black and Root Rivers join the Mississippi. The District's habitat base support large concentrations of migratory waterfowl, including tundra swans and canvasbacks. The popular Lake Onalaska is located in the District. The lake, like many of the Refuge backwaters, was created upon completion of the Lock and Dam System and subsequent flooding in 193 7. Lake Onalaska supports one of the most highly utilized fishery resources on the Upper Mississippi River. The District Office is co-located in the U.S. Fish and Wildlife Service Resource Center at • 555 Lester Avenue in Onalaska, WI; a storage warehouse is located near La Crescent, MN. • INTRODUCTION • TABLE OF CONTENTS PAGE HIGHLIGHTS .................................................. 1 CLIMATIC CONDITIONS ........................................ 2 1.

Reconstruction of the Long Lake Environmental Management Program (EMP) Project, severely damaged during the 2001 flood, was completed. The first phase of the Rosebud Island Protection Project was also completed (Section 2.c). About 2,200 acres of forest in Pool 8 were inventoried (Section 3.e). A first grade teacher and her class at La Crescent-Hokah Elementary School released beetles at Schnicks Bay to control purple loosestrife (Section 3.g). The proposed construction of an asphalt plant on Brice Prairie (Pool 7) has the potential to impact the Refuge (Section 5.a). Three tracts of land, totaling about 57 acres, were acquired in PoolS in FY2003 (Section 6.g). The boat ramp at Lower 1-90 Landing was replaced. Plans and specifications were finalized for rehabilitating the Long Lake Landing (Section 7 .a). • Thousands of coots and diving ducks on Lake Onalaska were killed by intestinal parasites during both fall and spring migration (Section 4.b). "Refuge Fest," the celebration of the NWRS Centennial, was a huge success in La Crosse (Section 7.a.)
