Johnson County has 111 dams in the federal inventory. The county's report-card score is driven by 38 high-hazard dams, 7 poor or unsatisfactory condition records, 6 high-hazard dams without a recorded Emergency Action Plan, and 20 high-hazard dams with blank or older inspection dates.

Interpretation: higher scores identify places where public records deserve closer review. The score does not predict failure probability and should be checked against official state and local dam-safety sources.
