About Ed Pylkas Dam
The primary purpose of Ed Pylkas Dam is flood risk reduction.

The dam is owned by Tioga County Soil & Water Conservation District (local government). It impounds the Dean Creek near Spencer.

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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 02/14/2024.
