About this dam

Norfleet Dam

Norfleet Dam, located in Suffolk, Virginia, is a state-regulated structure owned by an unspecified entity. This earth-type dam stands at 17 feet in height, serving primarily for recreational purposes on the TR-JONES SWAMP river or stream. With a storage capacity of 326 acre-feet, the dam's normal storage level is around 185 acre-feet, providing ample opportunities for outdoor activities in the area.

Despite being classified as "Undetermined" in terms of hazard potential and "Not Rated" in condition assessment, Norfleet Dam is subject to regular state inspection, enforcement, and permitting by the Department of Conservation and Recreation in Virginia. The dam has not been modified in recent years, and specific details regarding its construction year, length, and volume are unavailable. The dam's emergency action plan status and risk assessment measures are also undisclosed, suggesting a need for further evaluation and risk management procedures to ensure community safety and environmental preservation in the region.

Although specific information on Norfleet Dam's structural details and maintenance history is limited, its presence as a recreational water resource in Suffolk, Virginia, highlights the importance of ongoing monitoring and assessment for sustainable water management. As a vital component of the local landscape, the dam's role in supporting recreational activities underscores the need for continued regulatory oversight and risk mitigation strategies to uphold public safety and environmental resilience in the face of potential hazards and 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.

FAQ

About Norfleet Dam

Where does the data for Norfleet 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.
