Lewis Nursery Dam #1 Reservoir Report
Last Updated: February 25, 2026
Lewis Nursery Dam #1, also known as Big Pond Dam, is a crucial water resource structure located in Pittsylvania, Virginia.
Summary
This earth dam is primarily used for irrigation purposes and stands at a height of 28 feet, with a storage capacity of 95 acre-feet. It spans 450 feet in length and covers a surface area of 8.2 acres, serving as a vital component for managing water resources in the area.
Regulated by the Department of Conservation and Recreation in Virginia, Lewis Nursery Dam #1 plays a key role in maintaining water levels and ensuring the efficient utilization of water for agricultural needs. Despite its undetermined hazard potential and lack of a condition rating, the dam is regularly inspected and meets state regulatory standards for operation and enforcement. With a history dating back to an unspecified completion year, this dam continues to be a significant asset for the local community in managing water resources for irrigation purposes.
Owned by unspecified entities and located along Cow Branch, Lewis Nursery Dam #1 remains an essential infrastructure for water management in the region. As climate change impacts water resources, dams like Lewis Nursery Dam #1 play a crucial role in ensuring water availability for irrigation and agricultural activities, highlighting the importance of maintaining and monitoring these structures to sustainably manage water resources in Virginia.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
