Moriarity Lake Dam dam
Moriarity Lake Dam
Moriarity Lake Dam, located in Grant County, Indiana, is a privately owned earth dam completed in 2000 for recreational purposes. This dam, standing at a height of 25 feet and stretching 4367 feet in length, serves as a fish and wildlife pond while also providing recreational opportunities for visitors. With a normal storage capacity of 187.46 acre-feet and a maximum storage capacity of 302.8 acre-feet, the dam sits on an unnamed tributary of the Mississinewa River.
Despite its eye-catching features, Moriarity Lake Dam has a high hazard potential due to its location and design. The dam has not been rated for its condition as of the last inspection in July 2002, highlighting the need for regular monitoring and maintenance to ensure its safety and functionality. While the dam does not have a spillway or outlet gates, it is essential for the state regulatory agency, IDNR, to continue overseeing its inspection, enforcement, and permitting processes to mitigate potential risks and protect the surrounding environment.
For water resource and climate enthusiasts, Moriarity Lake Dam presents an intriguing case study of a privately owned dam contributing to both recreational and ecological purposes. Despite its high hazard potential, the dam's role in supporting fish and wildlife habitats and providing recreational opportunities underscores the importance of sustainable dam management practices. As discussions surrounding dam safety and climate resiliency continue to evolve, Moriarity Lake Dam serves as a reminder of the critical need to balance human activities with environmental stewardship in water resource management.

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 Moriarity Lake Dam
Where does the data for Moriarity 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.
