White Dam dam
White Dam
White Dam, located in Marion, Iowa, was completed in 1974 with a primary purpose of serving as a fire protection reservoir and stock or small fish pond. Owned privately, this earth dam stands at a height of 35 feet and stretches 385 feet in length, with a storage capacity of 46 acre-feet. Situated on TR-Coal Creek, the dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
The dam's low hazard potential and moderate risk assessment make it a crucial asset for the surrounding community, providing essential water storage for firefighting efforts and agricultural needs. Managed by the USDA NRCS, White Dam serves as a testament to effective water resource management and climate resilience measures. Despite being uncontrolled, the spillway type of the dam ensures safe discharge of excess water during heavy rainfall events, mitigating flood risks in the area.
With its strategic location and functional design, White Dam exemplifies the synergy between water infrastructure development and environmental stewardship. As water resource and climate enthusiasts, the significance of White Dam lies in its contribution to sustainable water management practices and resiliency against natural hazards. As a privately owned structure, the dam stands as a testament to the collaborative efforts between private entities and regulatory agencies in safeguarding water resources for future generations.

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 White Dam
Where does the data for White 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.
