Summary
This earth dam, completed in 1992, stands at a height of 31 feet and stretches 577 feet in length, with a storage capacity of 89 acre-feet. The dam regulates the flow of Aldrich Creek and serves to reduce flood risks in the area.
With a low hazard potential and a moderate risk assessment rating of 3, West Aldrich Subwatershed Site 14-A-1 is a crucial component of water resource management in the region. The dam, regulated by the Iowa DNR, is inspected, permitted, and maintained by state authorities to ensure its structural integrity and safety. Its location in Ida County, Iowa, highlights the importance of sustainable water infrastructure in protecting communities and ecosystems from the impacts of climate change.
As a part of the Rock Island District, West Aldrich Subwatershed Site 14-A-1 plays a vital role in water conservation efforts, with a surface area of 6.9 acres and a drainage area of 0.32 square miles. The dam's primary purpose, along with flood risk reduction, underscores its significance in maintaining water quality and availability for both human and ecological needs. Its presence serves as a reminder of the interconnectedness of water resources and climate resilience in the face of a changing environment.

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.
