Summary
Owned by the local government, this dam was completed in 1977 with a primary purpose of flood risk reduction along the Walnut Creek-TR river or stream. Designed by USDA NRCS, this buttress-type dam stands at a height of 32 feet with a hydraulic height of 26 feet and a structural height of 32 feet. It has a storage capacity of 490 acre-feet and a normal storage of 10.1 acre-feet, covering a surface area of 4.1 acres.
This low hazard potential dam in Ness County, Kansas, is under state regulation and jurisdiction, with the Kansas Department of Agriculture overseeing its permitting, inspection, and enforcement. Despite not being rated for its condition assessment, Dd No 129 has not undergone any modifications since its completion. The dam features a spillway width of 50 feet and does not have outlet gates. With no associated structures, the last inspection of this dam was conducted in July 2014, with an inspection frequency of 0. While the risk assessment, emergency action plan, and inundation maps status remain unknown, Dd No 129 serves as a crucial infrastructure for flood risk management 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.
