Summary

The dam stands at a height of 24 feet and has a maximum storage capacity of 330 acre-feet, serving a drainage area of 0.03 square miles. Despite its significant hazard potential, the dam is currently in satisfactory condition, as assessed in June 2018, with a regular inspection frequency of every 3 years.

Owned by a private entity, Cecil Sand and Gravel Pond 7 is regulated by the Maryland Dam Safety agency and undergoes state inspections and enforcement. The dam, constructed with stone core and rock-soil foundations, spans 400 feet in length and covers a surface area of 14.6 acres. With no spillway in place, the dam features a needle outlet gate system for water release. In case of emergency, an Emergency Action Plan is in place, last revised in April 2021, to ensure proper risk management and communication with relevant authorities.

Water resource and climate enthusiasts would find Cecil Sand and Gravel Pond 7 to be an interesting case study, showcasing the intersection of private ownership, state regulation, and risk assessment in dam infrastructure. The dam's location along the Principio Creek-TR-OS and its vital role in tailings storage highlight the importance of effective dam management and maintenance to prevent potential hazards. With a high-risk assessment rating and regular inspections, this dam serves as a critical component of water resource management in Cecil County, Maryland.

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.
