Washington Co Road Dam 23-74-9 dam
Washington Co Road Dam 23-74-9
Washington CO Road Dam 23-74-9 in Washington County, Iowa, is a locally owned earth dam completed in 2005 for grade stabilization along TR- Honey Creek. The dam stands at a height of 27 feet with a length of 920 feet, providing a storage capacity of 481 acre-feet and covering a surface area of 23 acres. The dam is regulated by the Iowa Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite being rated as having low hazard potential, the dam's risk assessment indicates a moderate risk level of 3, prompting the need for ongoing risk management measures. The dam does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, highlighting areas for improvement in emergency preparedness. With its location in the Rock Island District and under the jurisdiction of the Washington County Engineer, this dam plays a crucial role in water resource management and climate resilience efforts in the region.
Water resource and climate enthusiasts interested in the infrastructure of Washington CO Road Dam 23-74-9 will find its detailed specifications and regulatory oversight intriguing. As a vital structure for grade stabilization along Honey Creek, this dam serves as a key component of the local government's efforts to manage water resources effectively. With a moderate risk level and the absence of certain emergency preparedness measures, there is a clear opportunity for further enhancements to ensure the safety and resilience of this important infrastructure in Washington County, Iowa.

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 Washington Co Road Dam 23-74-9
Where does the data for Washington Co Road Dam 23-74-9 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.
