Summary

Built in 1975 by the USDA NRCS, this earth dam stands at a height of 54 feet, with a storage capacity of 57 acre-feet, serving a drainage area of 0.08 square miles. Despite its low hazard potential, the dam plays a crucial role in flood risk reduction and irrigation in the region.

This site, situated along the TR-Indian Creek, is regulated by the Iowa Department of Natural Resources and undergoes regular inspections for safety and compliance. While the dam's condition is currently rated as "Not Rated," its risk assessment is moderate, highlighting the need for ongoing monitoring and risk management measures. With a surface area of 2.3 acres and a spillway type classified as "Uncontrolled," Indian Creek Watershed Site 26 presents a fascinating study for water resource and climate enthusiasts interested in sustainable water management practices and the intersection of infrastructure with environmental conservation efforts in the region.

Overall, Indian Creek Watershed Site 26 serves as a vital component of the local water resource infrastructure, contributing to the broader ecosystem health and resilience in Council Bluffs, Iowa. With its strategic location, diverse purposes, and regulatory oversight, this site epitomizes the intersection of human-made infrastructure with natural water systems, offering valuable insights for researchers, policymakers, and stakeholders invested in the sustainable management of water resources and climate resilience in the region.

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. 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

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, 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.
