High Grove Dam dam
High Grove Dam
High Grove Dam in Goochland, Virginia, is a state-regulated structure on Courthouse Creek that serves primarily for recreational purposes. The earth dam stands at a height of 30 feet and stretches 600 feet in length, with a storage capacity of 239 acre-feet. Owned by an unspecified entity and maintained in accordance with state regulations by the Department of Conservation and Recreation, this dam has not been rated for condition assessment, and its hazard potential is currently undetermined.
Located within the Norfolk District of Virginia, High Grove Dam offers a scenic spot for water resource and climate enthusiasts to explore. While the dam's specific construction date and details remain unclear, its presence contributes to the local landscape and provides opportunities for outdoor recreation. As the structure is not managed by federal agencies, its operations and maintenance fall under state jurisdiction, ensuring regular inspections and enforcement of safety measures.
Despite lacking a formal assessment of its condition, High Grove Dam continues to stand as a key feature along Courthouse Creek, offering a potential source of enjoyment for visitors seeking recreational activities in the area. With its moderate height and storage capacity, this dam exemplifies the importance of state-regulated structures in providing both leisure opportunities and essential water resource management within the region.

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 High Grove Dam
Where does the data for High Grove 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.
