Walton Lake Dam dam
Walton Lake Dam
Walton Lake Dam in Fairfield, Iowa, is a significant earth dam that was completed in 1900 for water supply purposes. The dam stands at a height of 35 feet and spans a length of 900 feet, holding a maximum storage capacity of 2,500 acre-feet. With a normal storage capacity of 920 acre-feet and a surface area of 75 acres, the dam plays a crucial role in managing water resources in the region.
Located on TR-Crow Creek, the Walton Lake Dam is regulated by the Iowa Department of Natural Resources (DNR) and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a significant hazard potential, the dam's condition is assessed as satisfactory, with a moderate risk level. The spillway, with a width of 33 feet, is uncontrolled, emphasizing the importance of proper maintenance and monitoring to mitigate potential risks associated with the dam.
As a key infrastructure owned by the local government, Walton Lake Dam serves as a crucial water supply source for the community. With its historical significance dating back over a century, the dam's role in water management and climate resilience underscores the importance of sustainable resource utilization and proactive risk management strategies 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 Walton Lake Dam
Where does the data for Walton 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 Significant 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.
