Summary

Constructed in 1975 by the USDA NRCS, this earth dam stands at a height of 50 feet and stretches 620 feet in length, providing a storage capacity of 253 acre-feet. With a spillway width of 60 feet and a maximum discharge of 289 cubic feet per second, Klein Dam plays a critical role in managing water flow and protecting downstream areas.

The dam also serves as a hub for recreational activities and wildlife conservation, offering a 9.75-acre surface area for fishing and other outdoor pursuits. Despite its low hazard potential, Klein Dam is regulated by the Kansas Dept. of Agriculture and undergoes regular inspections to ensure its structural integrity and safety. With a moderate risk assessment rating, measures are in place to manage any potential risks associated with the dam, highlighting its importance in both water resource management and public safety.

As part of the Missouri River watershed, Klein Dam contributes to the overall hydrological system of the region, showcasing the interconnected nature of water resources and climate dynamics. With its strategic location and multiple purposes, including debris control, fish and wildlife habitat, and recreation, Klein Dam exemplifies the importance of sustainable infrastructure development in balancing human needs with environmental conservation. As water resource and climate enthusiasts, understanding the significance of structures like Klein Dam is essential in promoting resilience and adaptation to changing climate conditions.

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.
