Red Cedar Lake Two Dam dam
Red Cedar Lake Two Dam
Red Cedar Lake Two Dam, located in Loudoun, Virginia, serves the primary purpose of irrigation and is privately owned. This earth dam stands at 28 feet high with a length of 300 feet, providing a storage capacity of 174 acre-feet. Situated on TR-Goose Creek, the dam is regulated by the Department of Conservation and Recreation in Virginia, ensuring state permitting, inspection, and enforcement protocols are in place. Despite being classified as having a significant hazard potential, the dam's condition assessment as of August 2019 is considered fair.
The dam's location within the Baltimore District and its association with the river/stream network make it a vital structure for water resource management in the area. With a surface area of 4.3 acres and a drainage area of 0.96 square miles, Red Cedar Lake Two Dam plays a crucial role in storing water for irrigation purposes. The dam's last inspection in August 2019 revealed its fair condition, prompting ongoing monitoring and risk management measures to ensure the safety and efficiency of its operations. The presence of state-regulated protocols and enforcement mechanisms underscores the commitment to maintaining the dam's integrity and functionality for the community.
As an essential component of the water infrastructure in Loudoun, Virginia, Red Cedar Lake Two Dam stands as a testament to the critical role of private owners in managing water resources. With a history of state regulation and periodic inspections, the dam's significance in irrigation and water storage cannot be understated. As climate change continues to impact water availability and usage, structures like Red Cedar Lake Two Dam will play a vital role in ensuring sustainable water management practices for future generations of residents and agricultural stakeholders in the region.

About Red Cedar Lake Two Dam
Where does the data for Red Cedar Lake Two 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 Significant 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.
