Moulton Watershed Site B-2 dam
Moulton Watershed Site B-2
Moulton Watershed Site B-2 is a key water resource located in Appanoose County, Iowa, specifically in the city of Coal City. Managed by the local government and designed by USDA NRCS, this site serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. Built in 1962, the primary dam type is earth and it stands at a height of 30 feet with a length of 409 feet, providing a storage capacity of 106 acre-feet.
With a low hazard potential and a moderate risk assessment rating, Moulton Watershed Site B-2 is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement. The dam's condition is currently not rated, but it has not shown any significant modifications since its last inspection in 1960. Despite its small drainage area of 0.3 square miles, this site plays a crucial role in water management and protection along the TR-Chariton River.
Water resource and climate enthusiasts will appreciate the significance of Moulton Watershed Site B-2 as a vital infrastructure for controlling floods, providing water for livestock, and enhancing biodiversity in the region. Its location within the Rock Island District underlines its importance in maintaining the ecological balance of the surrounding area. As efforts continue to monitor and assess the condition of this dam, it remains a valuable asset for water conservation and sustainable development in Iowa.
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 Moulton Watershed Site B-2
Where does the data for Moulton Watershed Site B-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 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.
