Driftless AreaSettlement
IowaPlace
The streams of the Iowa Driftless Area occupy old entrenched valleys, have high gradients, and transport cool waters flowing rapidly over rocky substrates. Water quality, overall, is relatively high when judged by either physio-chemical characteristics or stream communities. Distribution of aquatic biota largely reflects the habitats provided by spring-fed streams
