Moulton Watershed Site E-1 dam
Moulton Watershed Site E-1
Moulton Watershed Site E-1, located in Coal City, Iowa, is a local government-owned earth dam completed in 1964 by the USDA NRCS. This dam serves multiple purposes including fire protection, livestock watering, small fish pond, and flood risk reduction along the TR-Chariton River. With a height of 31 feet and a length of 685 feet, the dam has a storage capacity of 91 acre-feet and covers a surface area of 4 acres.
Managed by the Iowa Department of Natural Resources, this dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation. Despite being classified as low hazard potential, the dam is considered to have moderate risk due to its age and condition assessment not being rated. The risk management measures and emergency action plan for the dam have not yet been fully assessed, highlighting the need for continued monitoring and maintenance to ensure the safety of the surrounding community and environment.
Water resource and climate enthusiasts interested in the Moulton Watershed Site E-1 can appreciate its role in water management and flood risk reduction in the area. The dam's location in the Appanoose County provides a valuable resource for agricultural and environmental sustainability. With its historical significance and ongoing regulatory oversight, this dam serves as a critical infrastructure for water conservation efforts in 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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Moulton Watershed Site E-1
Where does the data for Moulton Watershed Site E-1 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.
