Cecil Sand And Gravel Pond 7 dam
Cecil Sand And Gravel Pond 7
Cecil Sand and Gravel Pond 7, located in Perryville, Maryland, is a private earth dam completed in 2017 with a primary purpose of tailings storage. 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.
- 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.
- 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.
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, environmental 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.

About Cecil Sand And Gravel Pond 7
Where does the data for Cecil Sand And Gravel Pond 7 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
