About this dam

Cage Dam

Cage Dam, located in Halifax, Virginia, is a privately owned earth dam with a primary purpose of recreation. Standing at a height of 24 feet, the dam provides a storage capacity of 138 acre-feet and serves the Rocky Branch Woods Creek. Despite being state-regulated and inspected, the hazard potential and condition assessment of Cage Dam remain undetermined and not rated, respectively.

Owned by a private entity, Cage Dam is situated in a picturesque setting, offering recreational opportunities for water resource and climate enthusiasts. Although its specific construction date and details are unknown, the dam's presence contributes to the conservation and management of water resources in the area. As a state-regulated structure, it undergoes regular inspections to ensure safety and compliance with regulations.

While the exact risk assessment and management measures for Cage Dam are currently unspecified, its role in providing recreational benefits and contributing to the local ecosystem cannot be overlooked. With its strategic location and connection to the Rocky Branch Woods Creek, the dam serves as a vital component in the water infrastructure of Halifax, Virginia. As enthusiasts continue to admire and study the impact of Cage Dam on the surrounding environment, further insights into its management and potential risks may emerge.

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 Cage Dam

Where does the data for Cage 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.
