Summary

Built in 1964 by the USDA NRCS, this earth dam stands at a height of 41 feet and stretches for 1450 feet, with a storage capacity of 3363.87 acre-feet. Situated on Shaw Creek, its primary purpose is to mitigate the risk of flooding in the area, providing essential protection to the local community.

Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No 2-1 has a low hazard potential and a moderate risk assessment rating. Despite not being currently rated for condition assessment, the dam continues to serve its purpose effectively. With a spillway width of 180 feet and a maximum discharge capacity of 6886 cubic feet per second, this structure plays a crucial role in water resource management in the region.

As a key component of the water infrastructure in Kansas, Frd No 2-1 exemplifies the importance of effective dam management for flood risk reduction. With its strategic location and significant storage capacity, this earth dam stands as a testament to the collaborative efforts of local and federal agencies in safeguarding communities against potential water-related disasters.

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.
