Tomlinson Lake Dam dam
Tomlinson Lake Dam
Tomlinson Lake Dam, also known as Tomlinson Run Dam, is a gravity dam located in Hancock, West Virginia. Completed in 1936, this state-owned structure serves a primary purpose of recreation along the Tomlinson Run river. Standing at a height of 38 feet with a hydraulic height of 28 feet, the dam has a storage capacity of 532 acre-feet and a normal storage level of 325 acre-feet.
Despite its historical significance and recreational value, Tomlinson Lake Dam has been flagged for significant hazard potential and poor condition assessment in recent years. With the last inspection conducted in March 2019, the dam is in need of regular monitoring and maintenance to ensure its safety and longevity. The Emergency Action Plan (EAP) for the dam was last revised in February 2021, highlighting the need for proactive measures to address any potential risks associated with the dam's operation.
As a key feature in the Pittsburgh District managed by the US Army Corps of Engineers, Tomlinson Lake Dam serves as a vital resource for water management and recreational activities in the region. With its picturesque location and historical significance, the dam continues to attract water resource and climate enthusiasts seeking to explore its impact on the surrounding environment. Despite its current condition assessment, efforts are underway to ensure the safety and sustainability of this iconic structure for future generations to enjoy.

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 Tomlinson Lake Dam
Where does the data for Tomlinson 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 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 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.
