Indian Acres Of The Chesapeake Bay (Holly Drive) dam
Indian Acres Of The Chesapeake Bay (Holly Drive)
Indian Acres of The Chesapeake Bay (Holly Drive) is a privately owned earth dam located in Cecil, Maryland, along Dowdel Creek. Built in 1973 by Talbot, Wermers & Assoc., this dam primarily serves the purpose of recreation, with a storage capacity of 245 acre-feet and a surface area of 17.5 acres. The dam stands at a height of 15 feet and spans 200 feet in length, with a spillway width of 12 feet.
Despite its low hazard potential, Indian Acres of The Chesapeake Bay (Holly Drive) has been deemed to be in unsatisfactory condition as of the most recent assessment in April 2021. The dam is regulated by the Maryland Dam Safety agency, ensuring that it undergoes regular inspections and maintenance to mitigate any potential risks. With a moderate risk assessment rating of 3, it is crucial for stakeholders to implement proper risk management measures to ensure the safety and integrity of the structure.
While the dam currently poses a moderate risk, the implementation of effective risk management measures and regular inspections can help mitigate any potential hazards associated with the structure. As a focal point for recreation in the area, Indian Acres of The Chesapeake Bay (Holly Drive) serves as a vital resource for the community, emphasizing the importance of maintaining its structural integrity and ensuring the safety of all those who enjoy its recreational offerings.

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 Indian Acres Of The Chesapeake Bay (Holly Drive)
Where does the data for Indian Acres Of The Chesapeake Bay (Holly Drive) 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 Low 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.
