Prince's South Lake Dam (Not Built) dam
Prince's South Lake Dam (Not Built)
Prince's South Lake Dam, situated in Johnson, Indiana, was never actually built, despite its planned purpose for recreation. The dam's design was intended to be an earth dam with a height of 46 feet and a length of 485 feet, with a storage capacity of 778 acre-feet. The dam's location boasts a surface area of 32 acres and a drainage area of 0.73 square miles, making it an ideal spot for outdoor enthusiasts and nature lovers.
Despite its potential as a recreational hub, Prince's South Lake Dam remains in a state of limbo, with an undetermined hazard potential and a condition assessment that is labeled as "Not Rated." The last recorded condition assessment was conducted in January 2011, leaving the dam's safety and viability for public use in question. With no inspection frequency listed and no emergency action plan prepared, the future of Prince's South Lake Dam remains uncertain, highlighting the importance of proper oversight and maintenance for water resource infrastructure.
Although the dam may never see completion or active use, its existence as a planned structure serves as a reminder of the delicate balance between harnessing natural resources for human enjoyment and ensuring the safety and well-being of both the environment and the community. As water resource and climate enthusiasts, it is crucial to advocate for responsible stewardship of our natural landscapes to prevent potential hazards and protect the integrity of our water systems for future generations.
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 Prince's South Lake Dam (Not Built)
Where does the data for Prince's South Lake Dam (Not Built) 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 Undetermined 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.
