Mud Creek Subwatershed Site 15-1 dam
Mud Creek Subwatershed Site 15-1
Mud Creek Subwatershed Site 15-1, located in Plymouth County, Iowa, is a crucial earth dam structure designed by the USDA NRCS in 1973 for fire protection, stock, small fish pond, and flood risk reduction purposes. With a dam height of 36 feet and a length of 996 feet, this site has a storage capacity of 115 acre-feet and covers a surface area of 5.4 acres, serving a drainage area of 0.6 square miles. The dam is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement protocols, ensuring its safety and functionality.
Despite being classified as having a low hazard potential, the site is deemed to have a moderate risk rating of 3 due to its location and structural characteristics. The dam features an uncontrolled spillway type and is primarily constructed with soil foundations. While the condition assessment is currently not rated, the site's risk management measures and emergency action plan status are under review. The proximity of Mud Creek Subwatershed Site 15-1 to the TR-Mud Creek and its importance for local fire protection and flood risk reduction make it an essential water resource infrastructure in the region, managed by local government authorities and the Natural Resources Conservation Service.
Overall, Mud Creek Subwatershed Site 15-1 stands as an essential component of water resource management in Plymouth County, Iowa, catering to fire protection, stock, small fish pond, and flood risk reduction needs. With its regulated state jurisdiction and regular inspection processes, the site ensures the safety of its surrounding environment and communities. As a key earth dam structure with a significant storage capacity and surface area, this site exemplifies the importance of sustainable water resource management and climate resilience efforts 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 Mud Creek Subwatershed Site 15-1
Where does the data for Mud Creek Subwatershed Site 15-1 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.
