Mississinewa Dam dam
Mississinewa Dam
Mississinewa Dam, also known as Mississinewa Lake, is a federal-owned Earth dam located in Miami County, Indiana. Completed in 1967, the dam primarily serves to reduce flood risks in the area, with a capacity to store 368,400 acre-feet of water. The dam is situated on the Mississinewa River, with a spillway designed to release excess water during significant storm events to prevent flooding downstream.
However, while the dam plays a crucial role in flood risk reduction, there is still a potential for downstream flooding in extreme scenarios. The risk of a breach causing uncontrolled water surges remains a concern, particularly for towns like Peoria and Peru located below the dam. To manage these risks, the US Army Corps of Engineers (USACE) operates and maintains the dam, conducts regular inspections and emergency exercises, and collaborates with local communities to enhance flood preparedness.
Despite the potential hazards, the USACE's proactive risk management measures aim to minimize the impact of any unforeseen events. By closely monitoring water levels, conducting emergency drills, and engaging with local authorities, the USACE strives to safeguard downstream communities from the devastating consequences of a breach or high-volume water release. Mississinewa Dam stands as a vital piece of infrastructure in the region, protecting against floods while emphasizing the importance of continuous vigilance and preparedness in the face of natural disasters.

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 Mississinewa Dam
Where does the data for Mississinewa 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.
