Graceland College Dam dam
Graceland College Dam
Graceland College Dam, located in Lamoni, Iowa, was completed in 1959 and is primarily used for recreation. Managed by a private owner, the dam stands at a height of 12 feet and spans 624 feet along the TR-East Fork Big Creek. With a storage capacity of 80 acre-feet, the dam serves purposes such as irrigation and recreation for the local community. Despite being categorized as having a low hazard potential, the dam's condition assessment remains unrated.
The dam, constructed with an earth design and soil foundation, is regulated by the Iowa Department of Natural Resources and undergoes state inspection and enforcement regularly. With a moderate risk assessment rating, the dam's emergency action plan status, inundation maps, and risk management measures are currently undefined. The dam's location in Decatur County, Iowa, provides a vital resource for water storage and recreational activities, contributing to the environmental sustainability and enjoyment of the region's residents and visitors.
While the Graceland College Dam has not been significantly modified since its completion, its purpose in water resource management and recreation remains crucial. With its uncontrolled spillway type and moderate risk assessment, continued monitoring and maintenance are essential to ensure the safety and functionality of the dam for the surrounding community. As a significant landmark in the area, the dam serves as a reminder of the intersection between water resource management, climate resilience, and recreational opportunities in the region.

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 Graceland College Dam
Where does the data for Graceland College 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.
