Little Youghiogheny Site 5 dam
Little Youghiogheny Site 5
Little Youghiogheny Site 5, also known as Little Yok #5 (Wonderly's), is a local government-owned structure located in Loch Lynn Heights, Maryland. This dam on Landons Dam Run was designed by USDA NRCS and is regulated by the MD Dam Safety agency. Completed in 1968, the earth dam stands at a height of 41 feet, with a hydraulic height of 38 feet and a structural height of 45 feet. It serves primarily for flood risk reduction, with a storage capacity of 1500 acre-feet and a normal storage of 42 acre-feet.
With a high hazard potential and fair condition assessment, Little Youghiogheny Site 5 plays a crucial role in mitigating flood risks in the area. The dam has a moderate risk assessment rating of 3 and is inspected annually to ensure its structural integrity and safety. The spillway, an uncontrolled type with a width of 125 feet, allows for the controlled release of water during periods of excess flow. Despite its age, the dam continues to serve its purpose effectively and remains a vital asset in managing water resources in Garrett County.
Water resource and climate enthusiasts can appreciate the engineering marvel of Little Youghiogheny Site 5, with its strategic location and design contributing to the overall flood risk reduction efforts in the region. As one of the key structures in the area, this dam showcases the importance of proper regulation, inspection, and maintenance to ensure the safety of communities downstream. The collaboration between local government agencies and the USDA NRCS highlights the dedication to managing water resources effectively and protecting the environment for future generations.
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 5
Where does the data for Little Youghiogheny Site 5 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.
