The river is fed by several tributaries, including Honey and Turtle creeks, and is regulated by several dams, including the Backbone Lake Dam. The river experiences seasonal fluctuations, with high flows in the spring due to snowmelt and rainfall, and lower flows in the summer and fall. Interestingly, the Maquoketa River has been designated as an "Outstanding Iowa Water" due to its unique geology and ecology, including the underground karst limestone formations that create sinkholes and underground streams. Additionally, the river is a popular destination for kayaking and canoeing.
