Findley Lake was settled by War of 1812 veteran Alexander Findley, a native of Northern Ireland who had emigrated to America sometime around 1769, settled in eastern Pennsylvania, married and started a family, and returned to Ireland for a few years before making the decision to live permanently in the United States. After purchasing land in Greenfield, Pennsylvania, in 1805, he then purchased lot 52, near what is now Findley Lake, from the Holland Land Company in 1811, and built a dam there in 1815 to power his mill, thus creating the lake from two ponds. The settlement that grew up around the mills prospered.

​

The Lakeside Assembly on the southwest shore entertained visitors to the region, during the summers between 1895 and 1915, with programs that rivaled Chautauqua Assembly, at the Chautauqua Institution. Founded in 1895 by United Brethren minister Rev. C. G. Langdon, who lived in a parsonage on the lake's east shore, the Lakeside Assembly's first president was Dr. F. E. Lilley, who was succeeded by American Civil War veteran and U.S. Medal of Honor winner Ebenezer Skellie. The Assembly was reached by two steamboats, the Silver Spray and the Daisy. The United Methodist Church (which absorbed the United Brethren in 1968) continued to operate a summer camp, Camp Findley, in the hamlet of Findley Lake until the early 21st century.

​
