Manns Dam dam
Manns Dam
Manns Dam in Amelia, Virginia, is a privately owned earth dam primarily used for irrigation purposes. Standing at a height of 21 feet, the dam has a storage capacity of 52 acre-feet, making it a crucial resource for water management in the region. While the dam's hazard potential is currently undetermined and its condition is not rated, it is subject to state regulation and inspection by the Department of Conservation and Recreation to ensure its safety and compliance with regulatory standards.
Located within the Norfolk District, Manns Dam plays a vital role in water resource management in Amelia County. Despite lacking detailed information on its construction year and specific dimensions, the dam's presence signifies the importance of water storage and distribution for agricultural purposes in the area. With its state-regulated status and regular inspections, Manns Dam underscores the need for proper maintenance and oversight of critical infrastructure to support sustainable water management practices in the region.
As a key component of the local water infrastructure, Manns Dam serves as a valuable asset for irrigation and water resource management in Amelia, Virginia. While further details on the dam's design and operational history are limited, its significance lies in its role in supporting agricultural activities and ensuring water availability for the community. With ongoing regulatory oversight and state jurisdiction, Manns Dam continues to contribute to the resilience of the region's water supply and underscores the importance of sustainable water resource management practices in the face of changing climate conditions.

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 Manns Dam
Where does the data for Manns 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.
