Sleepy Hollow Lake Dam dam
Sleepy Hollow Lake Dam
Located in Oldham, Kentucky, Sleepy Hollow Lake Dam stands as a vital structure along the South Fork Harrods Creek, serving the primary purpose of recreation since its completion in 1922. This gravity dam, with a height of 23 feet and a length of 240 feet, provides a serene 9.2-acre surface area for water enthusiasts to enjoy. Regulated by the Kentucky Division of Water, the dam boasts a low hazard potential and fair condition assessment, making it a relatively safe and well-maintained site for visitors.
With a normal storage capacity of 70 acre-feet and a maximum storage of 79 acre-feet, Sleepy Hollow Lake Dam offers a picturesque setting for outdoor activities such as fishing, boating, and wildlife observation. Despite its moderate risk assessment rating, the dam's inspection frequency of every 5 years ensures that any potential issues are promptly addressed, guaranteeing the safety of both the dam and its surrounding environment. As part of the Louisville District, the dam contributes to the local ecosystem while providing a tranquil retreat for residents and visitors alike.
In the event of an emergency, the dam's emergency action plan (EAP) remains a critical component for effective risk management and response. While the EAP details may require updating, Sleepy Hollow Lake Dam's commitment to meeting regulatory guidelines and ensuring public safety underscores its significance as a cherished water resource within the community. Whether admiring the scenic views or engaging in recreational activities, Sleepy Hollow Lake Dam continues to captivate water resource and climate enthusiasts with its blend of natural beauty and engineered functionality.
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 Sleepy Hollow Lake Dam
Where does the data for Sleepy Hollow 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 Low 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.
