About Johnson/tadlock Dam

The primary purpose of Johnson/tadlock Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Henry Johnson;mathew & Laura Tadlock (private). It impounds the Little Kaw Creek-tr near Bonner Springs.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 06/24/2008. That was 17 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
