Summary
Completed in 2003 by King Engineering, this earth dam spans 275 feet in length and reaches a height of 36.2 feet, with a storage capacity of 120 acre-feet. The dam serves a primary purpose of flood control, with a spillway width of 40 feet to manage maximum discharge of 618 cubic feet per second. Despite its low hazard potential and moderate risk assessment, the 209 dam remains a critical infrastructure for the local government in Douglas County.
Owned and regulated by the Kansas Department of Agriculture, the 209 dam is subject to regular state inspections, enforcement, and permitting. The dam's condition is currently rated as "Not Rated," indicating a need for further assessment and risk management measures. While no associated structures or locks are present, the 209 dam plays a crucial role in protecting the surrounding area from potential flooding events. With a surface area of 3.8 acres and a normal storage capacity of 6.7 acre-feet, this dam is a vital asset for water resource enthusiasts in the region.
As a key feature of the local water infrastructure, the 209 dam represents a collaborative effort between state and federal agencies to ensure proper management and maintenance. With its uncontrolled spillway and buttress core design, the dam provides essential flood protection for the community. While its risk assessment is moderate, ongoing monitoring and risk management measures are essential to safeguarding the dam's integrity and functionality for years to come. For water resource and climate enthusiasts, the 209 dam serves as a prime example of effective water resource management in action.

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.
