Otwell Green Acres Dam dam
Otwell Green Acres Dam
Located in Accomack, Virginia, the Otwell Green Acres Dam is a privately owned structure regulated by the Department of Conservation and Recreation. With a height of 13.45 feet and a storage capacity of 211.7 acre-feet, this dam plays a crucial role in water resource management in the area. Despite its undetermined hazard potential and lack of a condition assessment rating, the dam serves as a significant infrastructure for the community.
Situated in the Baltimore District, the dam is overseen by the state regulatory agency and undergoes regular inspections. While specific details on its design, purpose, and construction are not provided, the dam's presence highlights the importance of maintaining and monitoring such structures for climate and water resource enthusiasts. With the potential to impact the surrounding environment and water systems, understanding the role and condition of the Otwell Green Acres Dam is essential for sustainable water management practices.
As climate change continues to affect water resources, the Otwell Green Acres Dam serves as a reminder of the interconnectedness between infrastructure, regulation, and environmental stewardship. With its location in Virginia and under the jurisdiction of state agencies, the dam represents a piece of the larger puzzle in ensuring water security and resilience in the face of changing climate patterns. For enthusiasts interested in water resource management and climate adaptation, the Otwell Green Acres Dam presents a case study worth exploring and understanding in the context of broader environmental challenges.

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 Otwell Green Acres Dam
Where does the data for Otwell Green Acres Dam 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 Undetermined 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.
