The Minnehaha Creek watershed is located west of Minneapolis, Minnesota. It drains approximately180 square miles of land into the Minnehaha Creek and ultimately the Mississippi River (Figure 1). The watershed includes Lake Minnetonka, Minnehaha Creek, the Minneapolis Chain of Lakes, and Minnehaha Falls. The Upper Watershed (referenced as UMCW), above Lake Minnetonka, is a region of rolling farmland interspersed with numerous lakes and wetlands. Lake Minnetonka discharges through a control structure, the Grays Bay Dam, into Minnehaha Creek. Lake Minnetonka covers an area of 122.6 square miles and has a maximum depth of 113 ft. It is comprised of numerous interconnected bays. Lake Minnetonka serves as both the recipient of stormwater runoff of the UMCW and as the source of Minnehaha Creek. The Lower Watershed (referenced as LMCW) consists of the area east of Lake Minnetonka that is drained by Minnehaha Creek and extends to the Mississippi River. Minnehaha Creek flows eastward for approximately 22 miles and is the physical link that binds the network of urban lakes, parks, and open space that define the western Twin Cities area and south Minneapolis. Some land area within the LMCW does not drain directly or indirectly to Minnehaha Creek, but drains directly or indirectly to the Mississippi River. Within the Minnehaha Creek watershed, approximately 29% of the land area is shown on the National Wetland Inventory as wetland. Prepared in collaboration with Army Engineer District, St. Paul, MN.
