Dd No 22b is a local government-owned dam located in Little River, Kansas, designed for flood risk reduction along the Little Arkansas River. 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.
