Mill Picayune Watershed Site M-2 dam
Mill Picayune Watershed Site M-2
Located in Crawford County, Iowa, the Mill Picayune Watershed Site M-2 is a crucial earth dam constructed in 1984 for fire protection, stock, and small fish pond purposes, as well as flood risk reduction. With a height of 37 feet and a length of 582 feet, this dam has a storage capacity of 236 acre-feet and covers a surface area of 7.7 acres. The watershed site is regulated by the Iowa Department of Natural Resources, ensuring regular inspections, enforcement, and permitting to manage water resources effectively.
The dam's primary purpose of fire protection and flood risk reduction highlights its importance in safeguarding the surrounding area, particularly in times of emergency. Despite being rated as having a significant hazard potential, the condition of the structure has not been formally assessed. Furthermore, the risk assessment for the site is moderate, indicating a need for ongoing monitoring and potential risk management measures to mitigate any potential threats to the dam and the community it serves. Overall, the Mill Picayune Watershed Site M-2 plays a vital role in water resource management and climate resilience efforts in the region.
With its location along Bee Tree Creek and under the jurisdiction of the local government, the Mill Picayune Watershed Site M-2 serves as a critical infrastructure for water storage and flood control in the area. As part of the Rock Island District, the dam provides essential water resource management functions while also supporting fire protection, livestock, and recreational activities. Moving forward, continued vigilance and maintenance of the dam will be essential to ensure its structural integrity and effectiveness in mitigating flood risks and protecting the local environment and community from potential water-related hazards.

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 Mill Picayune Watershed Site M-2
Where does the data for Mill Picayune Watershed Site M-2 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.
