Summary

The dam, classified as a Buttress type, serves the primary purpose of flood control along the Kill Creek-TR river or stream. With a storage capacity of 72 acre-feet, the dam has a high hazard potential, highlighting the importance of regular inspections and maintenance to ensure public safety.

Despite being owned by a federal agency and falling under Kansas state jurisdiction, Sunflower Pond B Dam is not regulated or permitted by the state. The dam's condition assessment is listed as "Not Rated," suggesting a need for further evaluation and potential upgrades to meet modern safety standards. Additionally, the dam lacks emergency action plans and inundation maps, raising concerns about its readiness to respond to potential disasters.

Water resource and climate enthusiasts in the area should take note of Sunflower Pond B Dam's location in DeSoto, Kansas, as well as its significant role in managing flood risk along the Kill Creek-TR. The dam's historical significance, combined with its high hazard potential and lack of state regulation, underscores the importance of ongoing monitoring and maintenance efforts to safeguard the surrounding community and environment.

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.
