Summary

With a primary purpose of recreation, the dam stands at a height of 14.4 feet and has a storage capacity of 69.1 acre-feet. The dam is regulated by the Department of Natural Resources in Ohio, ensuring that it meets state inspection and enforcement standards.

Located on a tributary to North Branch Creek, the dam spans 800 feet in length and covers a surface area of 5.9 acres. Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition as of its last inspection in 2016. The emergency action plan for the dam was last revised in October 2020, indicating ongoing efforts to ensure the safety and security of the surrounding community in case of any unforeseen events.

Water resource and climate enthusiasts will appreciate the vital role that Newfields Development Lake Dam plays in providing recreational opportunities while also maintaining water storage capacity for the region. As a focal point regulated by the state of Ohio, the dam's design by Ralph Woolpert Co. showcases engineering excellence in managing water resources effectively. With a robust inspection frequency and emergency action plan in place, the dam is a testament to the importance of proper maintenance and monitoring in safeguarding water resources for the future.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
