Crown Orchard Upper Dam dam
Crown Orchard Upper Dam
Crown Orchard Upper Dam in Albemarle, Virginia, is a state-regulated earth dam standing at a height of 38 feet along a tributary of Stillhouse Creek. With a storage capacity of 70 acre-feet, this dam plays a crucial role in water resource management in the area. Despite its undetermined hazard potential and not yet rated condition, the Department of Conservation and Recreation ensures regular inspections, permitting, and enforcement to maintain its safety and integrity.
Located in a picturesque setting, the Crown Orchard Upper Dam serves as a vital structure for water supply and flood control in the region. Its presence underscores the importance of proper dam management and the need for comprehensive risk assessment and emergency preparedness. With the involvement of state agencies and adherence to regulatory guidelines, this dam continues to fulfill its purpose effectively while ensuring the safety of surrounding communities and the environment.
As a water resource and climate enthusiast, the Crown Orchard Upper Dam offers a fascinating case study in dam construction and management. Its strategic location, design specifications, and regulatory oversight provide valuable insights into the intersection of infrastructure development, environmental conservation, and public safety. By staying informed about the latest updates and assessments related to this dam, enthusiasts can deepen their understanding of water resource dynamics and climate resilience efforts in the region.

About Crown Orchard Upper Dam
Where does the data for Crown Orchard Upper 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 below 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.

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.
