Summary
This site serves multiple purposes including fire protection, stock, and small fish pond, as well as flood risk reduction. With a dam height of 28 feet and a storage capacity of 51 acre-feet, this structure covers a drainage area of 0.2 square miles and has a surface area of 2.2 acres.
Managed by the Iowa DNR, Weber Creek Subwatershed Site 9-1900 has a low hazard potential and a moderate risk assessment score. Despite not being rated for its condition, this dam has not undergone any modifications and is currently not inspected or equipped with an Emergency Action Plan. The surrounding area is serviced by an uncontrolled spillway and lacks any associated locks or outlets. For water resource and climate enthusiasts, this site presents an opportunity to study the impact of dams on local ecosystems and water management practices in the region.
Although not meeting all regulatory guidelines, Weber Creek Subwatershed Site 9-1900 remains a significant structure in the Omaha District, providing valuable insights into dam construction, maintenance, and risk assessment. With its historical significance and multiple purposes, this site offers a unique case study for understanding the intersection of water resource management, climate resilience, and local government ownership in the state of Iowa.

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.
