Edel Dam dam
Edel Dam
Located in Mahaska County, Iowa, the Edel Dam stands as a vital structure for fire protection, stock, and small fish pond purposes. Constructed in 1975 by the USDA NRCS, this earth dam spans 410 feet in length and reaches a height of 22 feet, holding a storage capacity of 67 acre-feet. Situated on TR-Spring Creek in University Park, this dam is regulated by the Iowa Department of Natural Resources, ensuring its safety and functionality for the surrounding community.
With a hazard potential rated as low and a moderate risk assessment score of 3, the Edel Dam is considered a critical asset for the area. While the condition assessment is currently not rated, the dam undergoes regular inspections and meets state regulatory requirements. Despite its uncontrolled spillway type, the dam's location and design contribute to its low hazard potential and the overall safety of the surrounding area.
Water resource and climate enthusiasts will find Edel Dam an intriguing structure to study, given its significance in providing essential services like fire protection and stock water. As a privately owned dam maintained by the Natural Resources Conservation Service, its role in water management and conservation efforts in the region is undeniable. The dam's history, design, and regulatory oversight by the Iowa DNR make it a compelling case study for those interested in the intersection of water infrastructure and environmental stewardship.
Dam data reference
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 Edel Dam
Where does the data for Edel 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.
