Long Run Park Lake Dam dam
Long Run Park Lake Dam
Long Run Park Lake Dam, located in Jefferson County, Kentucky, serves as a key recreational spot along Floyds Fork. Built in 1968, this earth dam stands at a height of 43 feet and spans a length of 1050 feet, creating a lake with a storage capacity of 475 acre-feet. Despite its primary purpose for recreation, the dam's significant hazard potential and poor condition assessment in 2018 highlight the need for ongoing monitoring and maintenance efforts.
Managed by the local government, Long Run Park Lake Dam falls under the regulatory oversight of the Kentucky Division of Water. With a spillway width of 25 feet and uncontrolled spillway type, the dam faces moderate risk, prompting the need for detailed risk assessments and management measures. Given its location in a densely populated area, it is crucial for emergency preparedness plans to be in place to mitigate any potential hazards and ensure public safety.
Climate and water resource enthusiasts will find Long Run Park Lake Dam an intriguing case study, showcasing the intersection of recreational infrastructure, environmental regulation, and risk management. The dam's historical significance, coupled with its current maintenance challenges, offer valuable insights into the complexities of managing water resources in urban environments and the importance of proactive stewardship to safeguard both recreational amenities and public safety.

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 Long Run Park Lake Dam
Where does the data for Long Run Park 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.
