Roger's Folly No. 2 is a private-owned Earth dam located in Johnson County, Wyoming, specifically in Ranch House along the Schlicht Draw river. Built in 1964 by designer Laverne Nelson, this dam serves multiple purposes including fire protection, stock, small fish pond, and most importantly, fish and wildlife pond. With a structural height of 20 feet and a length of 352 feet, Roger's Folly No. 2 has a storage capacity of 181 acre-feet and covers a surface area of 15.1 acres.

Despite being classified as having a low hazard potential and fair condition assessment, the dam has a moderate risk level of 3. The spillway is uncontrolled with a width of 320 feet, and the maximum discharge capacity is 1397 cfs. The last inspection conducted in August 2018 revealed no significant issues, and the dam is maintained under the oversight of the Wyoming State Engineer's Office. With a drainage area of 8 square miles, Roger's Folly No. 2 plays a crucial role in supporting local fish and wildlife habitats while also providing recreational opportunities for the community.

In the event of an emergency, the dam lacks an Emergency Action Plan (EAP) and inundation maps, raising concerns about the preparedness for potential risks. The dam is not under the jurisdiction of the US Army Corps of Engineers and is subject to state regulations and inspections. With its unique design and importance for fish and wildlife conservation, Roger's Folly No. 2 stands as a testament to the intersection of human engineering and environmental stewardship in managing water resources and climate impacts.
