Summary
Completed in 1991, this earth dam stands at a height of 28.9 feet and has a storage capacity of 650 acre-feet, serving the important purpose of protecting the surrounding area from potential flooding events. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, highlighting the need for ongoing monitoring and maintenance to ensure its effectiveness in safeguarding the community.
Managed by the Kansas Department of Agriculture, Dd No 22b is subject to state jurisdiction, permitting, inspection, and enforcement to ensure compliance with regulatory standards. While the dam has not been modified in recent years and lacks a structured emergency action plan, its uncontrolled spillway and buttress core design contribute to its flood risk reduction capabilities. With a surface area of 17 acres and a drainage area of 2.24 square miles, Dd No 22b plays a crucial role in managing water resources and climate-related challenges in the region, demonstrating the importance of sustainable infrastructure for environmental resilience.
As climate change continues to impact water resources and weather patterns, the role of structures like Dd No 22b in mitigating flood risks becomes increasingly significant. With a focus on risk management and regulatory compliance, this dam serves as a vital asset in protecting the Little River community from potential inundation events. By prioritizing maintenance and monitoring efforts, local authorities can ensure the continued effectiveness of Dd No 22b in safeguarding against the unpredictability of climate-related challenges.

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.
