Deegan Lake dam
Deegan Lake
Deegan Lake, located in Harrison County, West Virginia, is a rockfill dam that was completed in 1950 for the primary purpose of recreation. The dam stands at a height of 31 feet and has a maximum storage capacity of 297 acre-feet. With a normal storage capacity of 163 acre-feet and a surface area of 18 acres, Deegan Lake provides a picturesque setting for outdoor activities such as fishing, boating, and picnicking.
Managed by the local government, Deegan Lake is regulated by the West Virginia Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity. The dam has a high hazard potential but has been deemed to be in satisfactory condition as of the last assessment in October 2015. Despite the potential risks, the dam continues to be a popular destination for residents and visitors alike, offering a tranquil escape in the midst of Davison Run.
As a vital water resource in the region, Deegan Lake plays a crucial role in providing recreational opportunities while also serving as a key flood control measure. With its beautiful surroundings and abundant wildlife, the lake serves as a haven for water resource and climate enthusiasts seeking to connect with nature and enjoy the benefits of sustainable water management in a picturesque setting.
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 Deegan Lake
Where does the data for Deegan Lake 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.
