Reed Subwatershed Sta 45+25 #4 dam
Reed Subwatershed Sta 45+25 #4
Located in Monona, Iowa, the Reed Subwatershed Sta 45+25 #4 is a locally owned earth dam completed in 1966 by the USDA NRCS with a primary purpose of fire protection, stock, or small fish pond. This low hazard potential dam on TR-McMaster Creek has a height of 51 feet, a length of 302 feet, and a drainage area of 0.38 square miles. With a normal storage capacity of 78 acre-feet and a maximum storage capacity of 105 acre-feet, the dam serves multiple purposes including flood risk reduction.
Maintained by the Iowa Department of Natural Resources, the Reed Subwatershed Sta 45+25 #4 dam is equipped with an uncontrolled spillway and is regularly inspected for safety and compliance. The risk assessment for this dam is categorized as moderate, indicating a potential need for risk management measures in the future. Despite its age, the dam's condition assessment is currently not rated, suggesting a need for further evaluation and maintenance to ensure its continued effectiveness in protecting the surrounding area from flood risks and providing essential water resources for the community.
Overall, the Reed Subwatershed Sta 45+25 #4 dam plays a crucial role in water resource management and climate resilience efforts in the Ticonic region. With its strategic location and design, this dam serves as a vital infrastructure for fire protection, stock maintenance, and small fish pond management, while also helping to mitigate flood risks in the area. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like this one will be essential to ensure the safety and sustainability of communities in the face of evolving environmental challenges.

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 Reed Subwatershed Sta 45+25 #4
Where does the data for Reed Subwatershed Sta 45+25 #4 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.
