Summary
Completed in 1935, this earth dam stands at a height of 19 feet and has a storage capacity of 410 acre-feet, providing water supply and recreational opportunities for the community. With a maximum discharge capacity of 2060 cubic feet per second, Mansfield Dam plays a vital role in managing water flow and ensuring the safety of nearby residents.
Despite its age, Mansfield Dam has stood the test of time and continues to serve its purpose effectively. The dam's hazard potential is rated as high, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity. While the dam's condition is currently not rated, its emergency action plan and risk management measures are crucial in mitigating any potential threats and ensuring the safety of the surrounding area in case of emergencies.
Managed by the local government, Mansfield Dam exemplifies the importance of sustainable water resource management and the need for continued investment in infrastructure to address the challenges of climate change. As a key component of the region's water supply and recreational infrastructure, Mansfield Dam plays a critical role in supporting the community's needs and promoting resilience in the face of evolving environmental conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
