Mosler Dam, located in Chetopa, Kansas, is a privately owned structure with a primary purpose of providing fire protection, stock, or serving as a small fish pond. Built in 1995 by the USDA NRCS, this earth dam stands at a height of 24.6 feet with a hydraulic height of 27 feet and a structural height of 28 feet. The dam has a storage capacity of 70 acre-feet, with a normal storage level of 32.8 acre-feet, covering a surface area of 5.5 acres and draining an area of 0.09 square miles.

Despite its fair condition assessment, Mosler Dam poses a significant hazard potential and is subject to regular inspections every five years. With a drainage area of 0.09 square miles, the dam has a maximum discharge capacity of 166 cubic feet per second but lacks a spillway. Although the dam has no associated locks, its outlet gates are listed as "None." The last inspection of Mosler Dam was conducted in March 2012, and while it meets state regulatory requirements, further risk assessment and management measures may be necessary to ensure its continued safety and functionality.
