The Wapsipinicon rises in the southeast corner of Mower County, Minnesota, at an elevation of 1250 feet above mean sea level and flows 255 miles in a southeasterly direction to enter the Mississippi River some five miles above Princeton, Iowa. In its course across northeast Iowa it falls approximately 685 feet, maintaining a rather gradual slope, the average seldom, if ever, exceeding 2.5 feet per mile. The major portion of the Wapsie basin lies within the area of the Iowan drift, and the topography for the major portion is a constructional type of the youthful stage. The Wapsie Valley is narrow (10 miles in width) and gives rise to no important major tributaries. Buffalo Creek, Little Wapsie, Otter and Plum Creek are the largest of the tributaries. The flat, narrow valley of the main river probably contains more overflow areas and backwater ponds than any other river in the state. This feature, besides enhancing fishing prospects, attracts numerous waterfowl and gives the river the reputation of being the best duck-hunting inland river of the state.
