The primary constituents of the South Fork Iowa River include agricultural runoff and precipitation. The streamgauge does not measure any specific related tributaries or dams. The seasonal trend of the South Fork Iowa River typically features lower flow rates in the late summer and higher flow rates in the spring due to snowmelt and precipitation. One interesting fact about the hydrology of the area is that the South Fork Iowa River was once a popular location for gold mining in the mid-1800s.
