About this dam

Camp Hydaway Lake Dam

Camp Hydaway Lake Dam, also known as Lake Hydaway, is a private dam located in Lynchburg, Virginia. Managed by the Department of Conservation and Recreation, this earth dam stands at a height of 16.7 feet and stretches 250 feet in length. With a primary purpose of recreation, this structure holds a normal storage capacity of 36.1 acre-feet, serving as a popular spot for outdoor enthusiasts to enjoy the surrounding Opossum Creek and James River.

Despite its recreational appeal, Camp Hydaway Lake Dam has been rated as having a poor condition assessment as of August 2019, with an undetermined hazard potential. The dam's spillway type is uncontrolled, with a width of 40 feet, allowing for a maximum discharge of 2727 cubic feet per second. While the risk assessment for this dam is moderate, there are no current emergency action plans or inundation maps prepared, highlighting the need for continued monitoring and maintenance to ensure the safety of the surrounding community and environment.

For water resource and climate enthusiasts, Camp Hydaway Lake Dam presents an intriguing case study in dam management and maintenance. With its location in the Wilmington District of Virginia and its association with Opossum Creek and the James River, this dam serves as both a recreational hub and a potential risk factor in the event of a breach. As discussions surrounding climate change and water resource management intensify, the importance of regularly inspecting and updating emergency protocols for structures like Camp Hydaway Lake Dam becomes increasingly evident.

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 Camp Hydaway Lake Dam

Where does the data for Camp Hydaway Lake 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.
