Henrico Prop Dam dam
Henrico Prop Dam
Henrico Prop Dam is a privately owned structure located in Henrico, Virginia, with a height of 8.5 feet and a storage capacity of 129.06 acre-feet. The dam, constructed along the NID storage system, serves various purposes under the regulation of the Department of Conservation and Recreation. Despite its relatively small size, the dam plays a crucial role in water resource management and climate adaptation efforts in the region.
With a condition assessment of "Not Rated" and an undetermined hazard potential, Henrico Prop Dam remains a critical infrastructure for the community. Although lacking in certain regulatory and emergency preparedness measures, the dam provides essential services for flood control, water supply, and environmental conservation. As climate change impacts water resources and weather patterns, the dam's role in mitigating risks and ensuring water security becomes increasingly important for sustainable development in the area.
As a non-USACE structure, Henrico Prop Dam highlights the significance of private ownership in water resource management and climate resilience. With ongoing inspections and potential modifications, the dam represents a vital component of the local ecosystem and a valuable asset for addressing future challenges related to water availability and extreme weather events. As water resource and climate enthusiasts, understanding the importance of structures like Henrico Prop Dam is crucial for promoting sustainable practices and ensuring the resilience of our communities in the face of changing environmental 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 Henrico Prop Dam
Where does the data for Henrico Prop 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.
