Facts About Poweshiek County, Iowa

Poweshiek County is almost a square, 24 miles by 24 miles. It is broken up into 16 townships, most of which are 6 miles by 6 miles. The townships are further broken up into one-square-mile sections, numbered 1 to 36, except for the irregular townships in the southern tier. The northern 3 tiers of townships in Poweshiek county are offset west of the southernmost tier.  This is because the "1st Line of Correction", established by the original surveyors to accommodate the Earth's curvature, passes through the county along the border between the two southern tiers of townships.
