About this dam

Lake Crystal Dam

Lake Crystal Dam, also known as Upper Crystal Lake, is a private structure located in Chesterfield, Virginia. Managed by the Department of Conservation and Recreation, this dam is regulated by the state and undergoes regular inspections and enforcement measures to ensure its safety and compliance with regulations. With a height of 18 feet and a storage capacity of 64 acre-feet, this dam plays a crucial role in managing the water resources in the area and mitigating flood risks for the tributary Falling Creek.

Despite its high hazard potential, Lake Crystal Dam's condition assessment is currently not rated. However, the emergency action plan (EAP) status and risk management measures are not specified in the available data. As a significant structure in the region, it is essential for stakeholders and enthusiasts in water resource management and climate resilience to stay informed about the latest developments and safety protocols related to Lake Crystal Dam. With its strategic location and impact on the surrounding environment, this dam serves as a vital component in the water resource infrastructure of Virginia.

Enthusiasts interested in water resource management and climate adaptation efforts can appreciate Lake Crystal Dam for its role in regulating water flow and storage. As a privately owned structure with state oversight, this dam exemplifies the importance of collaboration between private owners and regulatory agencies in ensuring the safety and functionality of critical infrastructure. With its location in Chesterfield, Virginia, and its association with the tributary Falling Creek, Lake Crystal Dam stands as a testament to the ongoing efforts to safeguard communities from potential flood risks and manage water resources effectively in 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.

FAQ

About Lake Crystal Dam

Where does the data for Lake Crystal 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 High 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.
