Summary
Managed by the local government with oversight from the Kansas Department of Agriculture, this dam is designed by USDA NRCS and constructed with a buttress core type. It stands at a height of 32 feet and has a storage capacity of 285.2 acre-feet, with a maximum discharge of 903 cubic feet per second.
The dam, situated on the NORTH BIG CREEK-TR river or stream, plays a crucial role in mitigating flood risks in the area. Despite its low hazard potential, the condition assessment for Dd No 3 is currently listed as 'Not Rated', indicating a need for further evaluation. With no associated structures and a minimal inspection frequency, there is a potential for improvement in monitoring and maintenance practices to ensure the continued effectiveness of this flood control infrastructure.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like Dd No 3 in safeguarding communities from potential flooding events. By staying informed about the condition and regulatory oversight of such dams, we can contribute to the sustainable management of water resources and the protection of our environment.

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.
