Summary

The dam, with a height of 33 feet and a length of 425 feet, provides storage of 130 acre-feet of water, with a normal storage capacity of 90 acre-feet. The dam is classified as an earth dam with a buttress core type and is situated on the TR TO ISUM CREEK, within the Kansas City District.

Despite being privately owned and not regulated by the state, the Lakes of Deerwood Number One Dam has a high hazard potential. The dam has not been inspected since 1987 and is currently rated as "Not Rated" in terms of condition assessment. Emergency action plans and risk management measures have not been updated or prepared for this dam, raising concerns about its safety and potential risks.

For water resource and climate enthusiasts, the Lakes of Deerwood Number One Dam presents an intriguing case study of a privately owned dam with limited oversight and maintenance. The dam's high hazard potential and lack of recent inspections highlight the importance of proper regulation and maintenance of these structures to ensure public safety and the effective management of water resources in the area.

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.
