Summary

Constructed in 1993, this earth dam stands at a height of 25 feet and spans a length of 310 feet. With a normal storage capacity of 26 acre-feet and a maximum storage of 47 acre-feet, the dam serves as a crucial resource for water management in the area.

Managed by the Iowa Department of Natural Resources, Schneider Dam is regulated, inspected, and enforced to ensure its safety and functionality. Despite being classified as low hazard potential with a moderate risk assessment, the dam has not been rated for its condition. With its strategic location on TR- Long Branch and its significance for fire protection and agricultural purposes, Schneider Dam plays a vital role in the local water resource infrastructure.

As a key element in the water management system of Marion County, Schneider Dam provides essential support for irrigation, livestock watering, and emergency fire suppression. With its earth structure and soil foundation, the dam contributes to the conservation and utilization of water resources in the region. Its moderate risk assessment underscores the importance of proper maintenance and monitoring to ensure the continued efficiency and safety of this valuable water resource infrastructure.

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.
