Summary

Built in 1966 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Walnut Creek-TR river or stream. With a height of 31 feet and a length of 720 feet, Frd No Gs 1 has a storage capacity of 211.08 acre-feet and covers a surface area of 4.81 acres, with a drainage area of 0.52 square miles.

Managed and regulated by the KS Dept. of Agriculture, Frd No Gs 1 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite being constructed over five decades ago, this dam continues to play a crucial role in mitigating flood risks in the area. With features like an uncontrolled spillway and no outlet gates, Frd No Gs 1 is designed to handle moderate risks and meet the guidelines for emergency action plans.

Located in the city of Reserve, Kansas, Frd No Gs 1 stands as a testament to effective water resource management and climate resilience efforts in the region. As water resource and climate enthusiasts, it is important to recognize the vital role that structures like Frd No Gs 1 play in safeguarding communities against the impacts of extreme weather events and ensuring sustainable water management practices for the future.

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.
