About this dam

Lake Lewman

Lake Lewman, also known as Lewman Lake, is a private water resource located in Rowan County, Kentucky. Managed by the Kentucky Division of Water, this reservoir was completed in 1967 for recreational purposes and covers a surface area of 24 acres. With a dam height of 47 feet and a storage capacity of 576 acre-feet, the lake is situated along the Island Fork river and is a popular spot for outdoor enthusiasts in the city of WALTZ.

Despite its fair condition assessment and high hazard potential, Lake Lewman is a beloved destination for water and climate enthusiasts seeking recreational opportunities in the Huntington District. With a spillway width of 60 feet and uncontrolled spillway type, the reservoir provides a picturesque setting for activities such as boating, fishing, and wildlife observation. While the risk assessment for the lake is moderate, its stunning natural surroundings and proximity to the Island Fork river make it a must-visit location for those interested in water resources and climate preservation.

As a privately owned water structure in Kentucky, Lake Lewman offers a unique glimpse into the importance of state regulations and inspections in maintaining the safety and integrity of such resources. With its drainage area of 0.46 square miles and maximum storage capacity of 576 acre-feet, the lake serves as a testament to the collaboration between government agencies and private owners in ensuring sustainable water management practices. Whether exploring its 580-foot dam length or enjoying its 380-acre normal storage capacity, Lake Lewman stands as a testament to the harmonious coexistence of water recreation and environmental conservation efforts in the region.

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.

FAQ

About Lake Lewman

Where does the data for Lake Lewman 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.
