Nasby Lake Dam dam
Nasby Lake Dam
Nasby Lake Dam in LaGrange, Indiana, is a state-owned earth dam completed in 1925 primarily for recreational purposes. Located on the Pigeon River, the dam stands at a height of 17 feet and has a length of 180 feet. With a maximum storage capacity of 306 acre-feet and a normal storage capacity of 198 acre-feet, the dam covers a surface area of 39.88 acres and drains an area of 224.49 square miles.
Despite its low hazard potential, Nasby Lake Dam has been assessed as being in poor condition as of 2005. The dam's last inspection took place in 2016, with a frequency of every five years. The risk assessment for the dam is moderate, with no specific risk management measures currently in place. The dam does not have a designated emergency action plan, and its inundation maps have not been prepared.
For water resource and climate enthusiasts, Nasby Lake Dam presents an interesting case study in the management and maintenance of aging infrastructure. As the dam continues to serve its recreational purpose, efforts to ensure its safety and resilience in the face of potential hazards will be crucial. With a moderate risk assessment and poor condition rating, there is a need for proactive measures to address any vulnerabilities and ensure the long-term sustainability of Nasby Lake Dam.

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 Nasby Lake Dam
Where does the data for Nasby 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 Low 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.
