This inventory identifies most of each township’s obvious barbed tributaries and elbows of capture as seen on 1:24,000-scale United States Geological Survey topographic maps, but should not be regarded as being complete. Also many of the barbed tributaries and elbows of capture are best seen and understood by observing the evidence in an area much larger than the listed township.
