Willis Dam dam
Willis Dam
Willis Dam, located in Mecklenburg, Virginia, is a state-regulated structure on the TR-POPES CREEK river. Owned by an unspecified entity, this earth dam stands at a height of 16 feet and serves primarily for recreation purposes, with secondary functions including irrigation. With a storage capacity of 56 acre-feet, the dam provides essential water resources for the surrounding area.
Despite being classified as having an undetermined hazard potential and not having a condition assessment rating, Willis Dam is regularly inspected by the Department of Conservation and Recreation in Virginia. Its emergency action plan status is unknown, with no information available on its risk assessment or management measures. The dam's location within the Norfolk District and its proximity to the city of Denver Riggleman's jurisdiction highlight its significance in water resource management and climate protection efforts in the region.
In conclusion, Willis Dam plays a crucial role in providing water storage for irrigation and recreational activities in Mecklenburg, Virginia. While its risk assessment and emergency preparedness status are unclear, the dam is subject to regulatory oversight and inspection by the state authorities. Its presence on the TR-POPES CREEK river underscores the importance of maintaining and monitoring such water resource infrastructure to ensure the safety and well-being of the surrounding community and environment.

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 Willis Dam
Where does the data for Willis 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.
