About this dam

Mayhew - New Pond Dam

Mayhew - New Pond Dam in Pittsylvania, Virginia, is a privately owned earth dam primarily used for irrigation purposes. The dam stands at a height of 25 feet and spans a length of 415 feet, with a storage capacity of 40 acre-feet. Situated in a spring and runoff-fed area, the dam is regulated by the Department of Conservation and Recreation in Virginia, ensuring state oversight for permitting, inspection, and enforcement.

While the hazard potential of the dam is currently undetermined and its condition is not rated, it is equipped with emergency action plans and contacts for potential risk management. The dam has not been modified in recent years, and its inspection frequency is reported as zero. The surrounding area covers a surface area of 3.4 acres, providing essential water resources for irrigation in the region.

Water resource and climate enthusiasts may find Mayhew - New Pond Dam an intriguing subject for study, given its location in a vital agricultural area and its role in providing water for irrigation. The dam's state jurisdiction, regulatory oversight, and modest storage capacity make it a noteworthy feature in the region's water infrastructure. Further research could explore the dam's history, construction, and potential risk management measures to ensure its long-term sustainability and resilience 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.

FAQ

About Mayhew - New Pond Dam

Where does the data for Mayhew - New Pond 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.
