Mucky Creek Subwatershed Sta 26+20 #3 dam
Mucky Creek Subwatershed Sta 26+20 #3
Mucky Creek Subwatershed Sta 26+20 #3 is a dam located in Mapleton, Iowa, along the TR-MAPLE RIVER. Built in 1965 by the USDA NRCS, this earth dam stands at 38 feet high and spans 502 feet in length, with a storage capacity of 39 acre-feet. The primary purposes of this dam are for fire protection, stock, or small fish pond use, as well as flood risk reduction for the local community in Monona County.
Managed by the Iowa DNR, Mucky Creek Subwatershed Sta 26+20 #3 is classified as having a low hazard potential and a moderate risk assessment level. With a drainage area of 0.34 square miles and a normal storage capacity of 23 acre-feet, this dam plays a crucial role in managing water resources in the area. While it has not been rated for its condition assessment, regular inspections, enforcement, and permitting ensure its continued safety and functionality.
Water resource and climate enthusiasts interested in the intersection of infrastructure and environmental conservation will find Mucky Creek Subwatershed Sta 26+20 #3 to be a fascinating case study. This dam not only serves practical purposes for the local community but also highlights the importance of responsible management and regulation in ensuring the safety and sustainability of water resources 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.

About Mucky Creek Subwatershed Sta 26+20 #3
Where does the data for Mucky Creek Subwatershed Sta 26+20 #3 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.
