Marion County Roadgrade Dam 25-76-19 dam
Marion County Roadgrade Dam 25-76-19
Marion County Roadgrade Dam 25-76-19, located in Red Rock Reservoir, Iowa, is a local government-owned structure on the TR-Des Moines River. Built in 1964 by Marion County Engineer, this earth dam stands at a height of 47 feet and spans a length of 1300 feet, providing a storage capacity of 562 acre-feet. The dam's primary purpose is categorized as "Other", with a low hazard potential and a moderate risk assessment.
Managed and regulated by the Iowa Department of Natural Resources, Marion County Roadgrade Dam 25-76-19 plays a crucial role in the local water resource management system. Despite being in operation for over five decades, the dam is currently rated as "Not Rated" in terms of condition assessment, with no recent inspection data available. The dam's emergency action plan status, risk management measures, and inundation maps preparation are also marked as unknown, highlighting the need for updated safety protocols and risk assessments to ensure the continued reliability of this essential infrastructure.
As an integral component of the regional water infrastructure, Marion County Roadgrade Dam 25-76-19 serves as a vital resource for flood control and water storage in the area. With ongoing monitoring and maintenance efforts, coupled with enhanced emergency preparedness and risk management measures, this dam continues to play a crucial role in safeguarding the surrounding communities from potential water-related hazards and ensuring sustainable water resource management practices in the region.
Dam data reference
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 Marion County Roadgrade Dam 25-76-19
Where does the data for Marion County Roadgrade Dam 25-76-19 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.
