Summary
Completed in 2005, this earth dam stands at a height of 27 feet with a length of 549 feet, providing a storage capacity of 75 acre-feet. Situated on TR- Squaw Creek in Ringgold County, this dam has a surface area of 6.9 acres and serves as a crucial water resource in the region.
Managed by the Iowa Department of Natural Resources, Walter Dam is regulated, inspected, and enforced to ensure safety and compliance with state guidelines. Despite its low hazard potential, the dam poses a moderate risk, warranting risk management measures. The dam's spillway type is uncontrolled, with a width of 1 foot, and it has not been modified since its completion. With its strategic location and purposeful design, Walter Dam plays a vital role in water conservation and management in the area.
For water resource and climate enthusiasts, Walter Dam serves as a prime example of sustainable water infrastructure. Its efficient design, state regulation, and risk assessment measures highlight the importance of responsible water management in mitigating potential hazards. As a key feature in the local landscape, this dam stands as a testament to the intersection of human ingenuity and environmental stewardship, embodying the critical role that water resources play in our ever-changing climate.

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.
