Sloan Dam dam
Sloan Dam
Sloan Dam in Iowa, completed in 1975, serves multiple purposes including fire protection, stock and small fish pond, as well as recreation. Managed by a private entity, the dam stands at 31 feet in height, with a length of 270 feet and a storage capacity of 48 acre-feet. The dam, primarily constructed of earth, is regulated by the Iowa Department of Natural Resources and has a low hazard potential with a moderate risk assessment score of 3.
Located in Davis County, Iowa, Sloan Dam is situated along the TR-Des Moines river and falls under the jurisdiction of the Rock Island District. The dam, designed by the USDA NRCS, has not been rated for its condition but is subject to regular state inspections and enforcement measures. Although categorized as having a moderate risk, the dam has not had an Emergency Action Plan (EAP) prepared or updated, highlighting potential areas for improvement in risk management.
Water resource and climate enthusiasts interested in Sloan Dam may find its multi-purpose design and regulatory oversight intriguing. With a focus on fire protection, stock pond management, and recreational activities, Sloan Dam plays a vital role in water resource management in the region. As efforts continue to enhance risk assessment and emergency preparedness, the dam serves as a focal point for collaboration between private owners, regulatory agencies, and the local community to ensure the safety and sustainability of its operations.

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 Sloan Dam
Where does the data for Sloan 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.
