Hants Lake Dam dam
Hants Lake Dam
Hants Lake Dam, also known as Prince's Hants Lake Dam, is a private dam located in Johnson County, Indiana. Completed in 1945, this earth-type dam serves primarily for recreational purposes, providing a surface area of 8.1 acres and a maximum storage capacity of 114 acre-feet. Situated on an unnamed tributary of Mud Creek, the dam stands at a height of 30 feet with a hydraulic height of 28 feet, making it a significant structure in the area.
The dam's spillway, which is uncontrolled and 20 feet wide, can handle a maximum discharge of 1782 cubic feet per second. Despite its significant hazard potential, the dam has been assessed as satisfactory in condition, with the last inspection conducted in April 2018. The risk assessment for Hants Lake Dam is moderate, with a DSAC (Dam Safety Action Classification) not yet assigned. With its picturesque location and recreational opportunities, Hants Lake Dam is a notable feature in the water resource and climate enthusiast community.
For those interested in water resource management and climate resilience, Hants Lake Dam offers a unique case study in private dam ownership and regulation. Its presence in the Louisville District underscores the importance of maintaining dam safety standards to mitigate risks and ensure the sustainability of water resources in the region. As climate change impacts continue to pose challenges for water infrastructure, the condition and management of dams like Hants Lake Dam are crucial for safeguarding communities and ecosystems against potential hazards.

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 Hants Lake Dam
Where does the data for Hants 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.
