Poplar Grove Lake Dam dam
Poplar Grove Lake Dam
Poplar Grove Lake Dam, located in Morgan County, Indiana, was completed in 1930 for the primary purpose of recreation. This private earth dam stands at a length of 1096 feet and has a surface area of 10.63 acres, providing a scenic water resource for enthusiasts to enjoy. While the dam is not regulated by the state and has not been inspected since 1995, its high hazard potential emphasizes the importance of proper maintenance and emergency preparedness.
Despite not having a state agency overseeing its regulation, Poplar Grove Lake Dam is a significant structure in the area, providing water storage and recreational opportunities for the community. The dam's condition is currently not rated, highlighting the need for a comprehensive assessment to ensure public safety and environmental conservation. With a risk assessment and management measures yet to be determined, the dam's hazard potential warrants attention from water resource and climate enthusiasts to address any potential risks and ensure long-term sustainability.
As climate change continues to impact water resources, the protection and maintenance of dams like Poplar Grove Lake Dam become increasingly vital. With its historical significance and recreational value, efforts to assess and manage risks associated with the dam are essential to safeguarding not only the structure itself but also the surrounding environment and communities that rely on it for water supply and recreation. Collaboration between private owners, state agencies, and stakeholders is crucial in ensuring the resilience and sustainability of this important water resource in Indiana.

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 Poplar Grove Lake Dam
Where does the data for Poplar Grove 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 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.
