Summary
Constructed in 1978 by the USDA NRCS, this earth dam stands at a height of 39 feet and has a length of 430 feet. With a storage capacity of 259 acre-feet and a normal storage of 133 acre-feet, this dam plays a crucial role in flood risk reduction in the area.
Managed by the Iowa DNR, Dane Ridge Watershed Site D-1-6 is state-regulated and undergoes regular inspections to ensure its structural integrity and functionality. The dam has a low hazard potential and a moderate risk assessment rating. Despite not being currently rated for condition assessment, this dam continues to play a vital role in protecting the surrounding area from flooding and providing essential water resources for fire protection and agricultural purposes.
With a surface area of 11.9 acres and a drainage area of 2.33 square miles, Dane Ridge Watershed Site D-1-6 serves as a key water resource in the region. The dam's location in the Welsh Creek Gully D-1 tributary highlights its importance in managing water flow and reducing the risk of flooding for nearby communities. As water resource and climate enthusiasts, understanding the significance of structures like this dam is crucial in ensuring sustainable water management practices for the future.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
