Backes Dam dam
Backes Dam
Backes Dam, located in Benton County, Iowa, was completed in 1967 and is primarily used for fire protection and as a stock or small fish pond. The dam, designed by USDA NRCS, stands at 26 feet high and stretches over 390 feet in length, with a storage capacity of 50 acre-feet. Despite its low hazard potential, the dam is state-regulated by the Iowa Department of Natural Resources and undergoes regular inspections and enforcement to ensure its safety and compliance.
Situated on the Cedar River, Backes Dam plays a vital role in water resource management in the region, with a drainage area of 0.12 square miles. The dam's spillway is uncontrolled, and it has a moderate risk assessment rating. While the dam has not been rated for its current condition, it continues to serve its purpose effectively for fire protection and water storage. The surrounding area benefits from the dam's presence, providing a source of water for agricultural and recreational activities.
Owned privately, Backes Dam operates under the jurisdiction of the Iowa DNR, with the primary source agency being the state of Iowa. The dam's structure, consisting of earth and soil foundations, is a testament to sustainable water management practices. Water resource and climate enthusiasts can appreciate the importance of dams like Backes Dam in maintaining water supply, supporting ecosystems, and mitigating risks associated with flooding and drought in the area.

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 Backes Dam
Where does the data for Backes 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.
