Carter Dam dam
Carter Dam
Carter Dam, located in Jefferson, Iowa, is a privately owned structure with a primary purpose of providing fire protection and serving as a stock or small fish pond. Constructed in 1967 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans a length of 428 feet. With a normal storage capacity of 22 acre-feet and a maximum storage capacity of 57 acre-feet, the dam overlooks the TR-BRUSH CREEK, offering essential water management in the area.
Managed and regulated by the Iowa DNR, Carter Dam has a low hazard potential and a moderate risk assessment rating of 3. Although the condition assessment is currently not rated, the dam is inspected, permitted, and enforced by state authorities, ensuring its operational safety. While the dam does not have any associated structures or outlet gates, it plays a crucial role in mitigating potential flood risks and safeguarding the surrounding environment in Rome, Iowa.
With its strategic location and essential functions, Carter Dam serves as a vital asset for water resource management and climate resilience in the region. As a key element in the local water infrastructure, the dam's construction, design, and regulatory oversight underscore its significance in providing sustainable water supply and protection against potential hazards. As water resource and climate enthusiasts, the data on Carter Dam highlights the importance of robust infrastructure and responsible management practices in ensuring the resilience of our water systems.

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 Carter Dam
Where does the data for Carter Dam 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.
