The Maquoketa River is a tributary of the Mississippi River located in the Midwest United States. The river stretches for approximately 150 miles, starting from its source in Hancock County, Iowa and ending at its confluence with the Mississippi River in Jackson County, Iowa. The river is known for its rich history, including Native American settlements and European exploration. Today, the river is used for a variety of recreational activities such as fishing, boating, and camping. The river also serves as a source of irrigation for agricultural purposes. However, the river has faced challenges due to the construction of several dams and reservoirs that have altered its natural hydrology. These include the Backbone Lake Dam and the Lake Delhi Dam, which have been the subject of controversy due to their environmental impact.
