Dd No 101, also known as Allen Creek Watershed Dam No 101, is located in Lyon County, Kansas, near the city of Emporia. This earth dam, with a height of 17.5 feet and a hydraulic height of 24 feet, was designed by the USDA NRCS for the primary purpose of flood risk reduction. With a storage capacity of 86 acre-feet and a drainage area of 0.49 square miles, this dam plays a crucial role in managing water flow in the region.

Despite its low hazard potential and satisfactory condition assessment, Dd No 101 has not been inspected since March 2011. It has a moderate risk rating and is classified as uncontrolled spillway type with a spillway width of 86 feet. The dam has no outlet gates and is associated with the Dow Creek-TR river or stream. It is owned by the local government and funded by the Natural Resources Conservation Service, highlighting the collaborative effort to protect the community from potential flood risks.

While Dd No 101 serves its purpose effectively in flood risk reduction, there are concerns regarding the lack of recent inspections and maintenance activities. With its strategic location and significant contribution to water resource management, it is essential for relevant authorities to prioritize regular assessments and necessary upgrades to ensure the continued safety and effectiveness of this vital infrastructure.
