Summary
The dam, designed by SCS, is classified as an earth dam with a height of 31 feet and a length of 200 feet. It has a normal storage capacity of 30 acre-feet and a maximum storage of 50 acre-feet, serving the Iowa River and TR-ROFF CR. The dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state authorities.
Despite its low hazard potential, Walker Dam poses a moderate risk level of 3 due to its condition assessment being labeled as "Not Rated." The dam does not have an emergency action plan in place or updated inundation maps prepared. It is not under the jurisdiction of the US Army Corps of Engineers and does not have any associated federal agencies for funding, construction, or operation. The structure is in need of further risk assessment and management measures to ensure the safety of the surrounding area and water resources.
For water resource and climate enthusiasts, Walker Dam serves as a vital infrastructure for fire protection and wildlife habitat in Louisa County, Iowa. Its presence contributes to the local ecosystem and provides essential water storage for agricultural and environmental purposes. However, with the risk level considered moderate and the condition assessment not rated, there is a pressing need for enhanced monitoring, maintenance, and emergency preparedness to mitigate potential hazards and ensure the long-term sustainability of the dam and its surrounding areas.

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.
