Summary
Built in 1968 by the USDA NRCS, this earth dam stands at a height of 37 feet with a hydraulic height of 34 feet and a length of 585 feet. With a normal storage capacity of 38 acre-feet and a maximum storage of 496.18 acre-feet, this dam plays a crucial role in managing water resources in the Walnut Creek-TR watershed.
Located in Padonia, Kansas, Frd No Gs 3a is regulated by the Kansas Department of Agriculture and is subject to state inspections, enforcement, and permitting. Despite its low hazard potential, the dam is considered to have a moderate risk level of 3, highlighting the importance of ongoing risk management measures. The structure features an uncontrolled spillway with a width of 80 feet and no outlet gates, reflecting its design for flood risk reduction in the region.
Although the condition of Frd No Gs 3a is currently not rated, the dam remains a key component of the local water management infrastructure. With its strategic location in the Walnut Creek-TR watershed and its role in reducing flood risks, this earth dam stands as a testament to the collaborative efforts between local government agencies and the USDA NRCS to protect communities and safeguard water resources in the region.

Dam Data Reference
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.
