Dd No 3-16a is a dam located in Jackson, Kansas, with a primary purpose of flood risk reduction. Constructed in 1991 by the USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 106.82 acre-feet. The dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections, with a low hazard potential rating.

Despite its low hazard potential, Dd No 3-16a is still considered to have a moderate risk level, with a risk assessment rating of 3. The dam features an uncontrolled spillway with a width of 40 feet and covers a surface area of 5.1 acres. With a normal storage capacity of 32.84 acre-feet and serving a drainage area of 0.24 square miles, this dam plays a crucial role in mitigating flood risks in the region.

While the dam has not been rated for its condition assessment, it meets state regulations and is part of the state's jurisdiction for permitting, inspection, and enforcement. Despite its relatively low hazard potential, the moderate risk level indicates a need for ongoing risk management and potentially the development of an Emergency Action Plan to ensure the safety and effectiveness of Dd No 3-16a in the face of changing climate patterns and water resource management challenges.
