Little Youghiogheny Site 7 dam
Little Youghiogheny Site 7
Little Youghiogheny Site 7, also known as Little Yok #7, is a local government-owned dam located in Deer Park, Maryland along the Little Youghiogheny River. Constructed in 1960 by the USDA NRCS, this earth dam stands at a height of 45 feet and spans 700 feet in length, serving primarily for flood risk reduction purposes. With a storage capacity of 1155 acre-feet, this structure plays a crucial role in managing water flow and mitigating potential hazards in the area.
Despite being assessed as in fair condition during the last inspection in April 2021, Little Youghiogheny Site 7 poses a high hazard potential due to its location and purpose. The dam's spillway, with a width of 90 feet, is uncontrolled, and its normal storage capacity is 31 acre-feet. With a moderate risk assessment rating of 3, ongoing risk management measures and inspections are imperative to ensure the safety and integrity of this essential water resource infrastructure. Local residents and stakeholders rely on this dam for protection against flooding and safeguarding the surrounding environment.
As a vital component of the local water management system, Little Youghiogheny Site 7 plays a crucial role in protecting the community and ecosystem in Garrett County, Maryland. With a high hazard potential and moderate risk assessment, continued monitoring, maintenance, and emergency preparedness are essential to ensure the dam's effectiveness in flood risk reduction. The collaboration between the local government, regulatory agencies, and the USDA NRCS is key to upholding the safety and functionality of this important water resource infrastructure for years to come.
Dam data reference
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 Little Youghiogheny Site 7
Where does the data for Little Youghiogheny Site 7 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.
