Lake Marian (Woodridge Road) dam
Lake Marian (Woodridge Road)
Lake Marian (Woodridge Road) is a privately owned dam located in Frederick Junction, Maryland. Built in 1973 by the Robert B. Balter Co., this earth dam serves the primary purpose of debris control and also supports water supply functions. With a height of 50 feet and a length of 300 feet, the dam has a storage capacity of 113 acre-feet, with a normal storage level of 64 acre-feet. The dam's low hazard potential and satisfactory condition assessment make it a reliable structure for managing Linganore Creek-TR's drainage area of 1.2 square miles.
The dam features an uncontrolled spillway with a width of 16 feet and needle outlet gates to regulate water flow. Despite being regulated by the Maryland Dam Safety agency and subject to inspection and enforcement, the dam has a moderate risk assessment rating of 3. The surrounding area of Lake Marian offers a surface area of 3.7 acres for recreational activities and wildlife habitat. With its strategic location and crucial role in water resource management, Lake Marian (Woodridge Road) stands as a testament to sustainable infrastructure development in Maryland.
Overall, Lake Marian (Woodridge Road) is a vital asset in Frederick County, Maryland, providing essential services for debris control and water supply. With its robust construction and satisfactory condition, the dam ensures the safety and well-being of the surrounding community while contributing to the conservation of the Linganore Creek-TR watershed. As a key component in the state's water resource infrastructure, Lake Marian exemplifies the importance of sustainable dam management practices in mitigating climate-related risks and safeguarding natural ecosystems.

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.

About Lake Marian (Woodridge Road)
Where does the data for Lake Marian (Woodridge Road) 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 Low 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.
