Upper Peoga Lake Dam dam
Upper Peoga Lake Dam
Upper Peoga Lake Dam, located in Johnson County, Indiana, stands as a testament to water resource management and climate resilience. Built in 1946, this private-owned earth dam spans 400 feet in length and reaches a height of 30 feet, offering a storage capacity of 48 acre-feet. The dam's primary purpose is to control the flow of an unnamed tributary of Mud Creek, with a spillway width of 35 feet and a maximum discharge capacity of 211 cubic feet per second.
Despite its critical role in water management, Upper Peoga Lake Dam poses a high hazard potential due to its unsatisfactory condition assessment and its location within a moderate risk zone. The dam's emergency action plan and risk assessment require significant updates to meet modern guidelines and ensure effective management of potential hazards. With its valve outlet gates and state-regulated status, the dam serves as a focal point for ongoing inspection, maintenance, and enforcement efforts by the Indiana Department of Natural Resources.
For water resource and climate enthusiasts, Upper Peoga Lake Dam presents a unique case study in the intersection of infrastructure, risk management, and environmental stewardship. As climate change intensifies the frequency and severity of extreme weather events, the resilience of dams like Upper Peoga Lake becomes ever more crucial. By understanding and addressing the challenges facing this dam, stakeholders can work towards enhancing its safety, sustainability, and capacity to adapt to a changing climate, ensuring the long-term protection of both the dam itself and the surrounding communities that rely on its water resources.

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 Upper Peoga Lake Dam
Where does the data for Upper Peoga 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.
