Summary
Constructed in 1955 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Arkansas River. Standing at a height of 19 feet with a hydraulic height of 15 feet, Dd No 8 has a storage capacity of 760 acre-feet and a maximum discharge of 400 cubic feet per second.
Managed by the Kansas Department of Agriculture, Dd No 8 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. With a buttress core type and unknown foundation, this low-hazard dam has not been rated for its condition and does not currently have an Emergency Action Plan in place. Although the dam has not undergone recent inspections or assessments, its design and purpose highlight its importance in mitigating flood risks for the surrounding community.
Water resource and climate enthusiasts interested in the infrastructure and management of dams will find Dd No 8 a fascinating subject for study. Its location, design, and purpose in flood risk reduction, coupled with its state-regulated status and historical significance, make it a valuable asset in the protection of the Arkansas River and surrounding areas in Kansas.

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.
