Summary

This gravity dam stands at a height of 14.99 feet and has a length of 445 feet, providing a normal storage capacity of 434.31 acre-feet. The dam's spillway, with a width of 140 feet, is of the Controlled type, ensuring effective water flow management.

The dam's hazard potential is categorized as high, with a fair condition assessment as of the last inspection in May 2020. Despite its risk level, the dam meets state regulatory requirements for inspection, enforcement, and permitting. With a very high risk assessment rating of 1, it is crucial for stakeholders and the state regulatory agency, DNREC, to implement appropriate risk management measures to mitigate potential hazards and ensure the safety and integrity of Mudmill Pond Dam for both wildlife conservation and recreational purposes.

For water resource and climate enthusiasts, Mudmill Pond Dam serves as a vital structure in the Choptank River watershed, providing essential habitat for fish and wildlife. As the dam continues to be monitored and maintained, it stands as a significant component of the region's ecological landscape, showcasing the intersection of human infrastructure with natural ecosystems.

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.
