Summary

Built in 1984 by the USDA NRCS, this dam serves primarily for recreation purposes along the Walnut Creek-TR river. With a height of 44.5 feet and a length of 1680 feet, the dam has a storage capacity of 1932 acre-feet and a normal storage level of 356 acre-feet.

Although Mpd No 34 has a low hazard potential, it is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture to ensure its safety and functionality. The dam features an uncontrolled spillway with a width of 250 feet, and a maximum discharge of 5662 cubic feet per second. While the condition assessment is currently not rated, the risk assessment indicates a moderate risk level (3) associated with the dam.

Water resource and climate enthusiasts can appreciate the importance of Mpd No 34 in flood risk reduction and recreational activities in the area. With its strategic location and design, Goodman Dam plays a crucial role in managing water flow and providing a safe environment for recreational activities along the Walnut Creek-TR river. The collaborative efforts of the local government, USDA NRCS, and regulatory agencies ensure the continued functionality and safety of this essential water infrastructure in Kansas.

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.
