Summary
Constructed in 1967 by USDA NRCS, this earth dam stands at a height of 26 feet and spans 330 feet in length. With a storage capacity of 33 acre-feet and a surface area of 1.3 acres, Lutz Dam plays a vital role in managing water resources in the region.
Managed by the Iowa Department of Natural Resources, Lutz Dam is regulated, inspected, and enforced to ensure its safety and compliance with state regulations. Despite its low hazard potential, the dam poses a moderate risk, prompting the need for risk management measures. The dam's location on TR-South Squaw Creek in Clarke County makes it a key component in the local water infrastructure, serving both practical and environmental purposes.
Water resource and climate enthusiasts will be intrigued by Lutz Dam's design and construction details, as well as its role in providing essential services such as fire protection and stock watering. The dam's presence in the Kansas City District highlights its significance in the regional water management system. With a focus on safety and risk assessment, Lutz Dam stands as a testament to the importance of sustainable water resource management in Iowa.

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.
