Walnut Creek Duck Marsh Dam dam
Walnut Creek Duck Marsh Dam
Walnut Creek Duck Marsh Dam, located in Ringgold County, Iowa, is a state-regulated structure designed by the Iowa Conservation Commission for recreational purposes. Completed in 1959, this earth dam stands at a height of 8 feet and spans a length of 3925 feet, with a storage capacity of 589 acre-feet. Situated on the TR-Walnut Creek, this dam serves as a vital resource for water storage and recreational activities in the area.
Despite being classified as having a low hazard potential and a moderate risk assessment, the condition of Walnut Creek Duck Marsh Dam has not been rated. The dam has not undergone inspection since November 1960, and there is no information available on emergency action plans or risk management measures. With its uncontrolled spillway and soil foundation, the dam's structural integrity and maintenance protocols may warrant further evaluation to ensure the safety and sustainability of the surrounding environment and communities.
As a critical infrastructure in the region, Walnut Creek Duck Marsh Dam plays a crucial role in water resource management and climate resilience efforts. With its proximity to Isadora, MO, and the oversight of the Iowa Department of Natural Resources, this dam serves as a reminder of the importance of regular inspections, maintenance, and emergency preparedness to safeguard against potential risks and ensure the long-term sustainability of water resources in the area.

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 Walnut Creek Duck Marsh Dam
Where does the data for Walnut Creek Duck Marsh 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.
