The lake was created for supplying a water race to Laurel Forge by an 1830 dam on Mountain Creek. In 1855 and again in 1889, the downstream Upper Mill dam (now Eaton-Dikeman mill) was breached by downwash when the Laurel Forge breached.[2]
The lake was a popular camp location. The Camp Rothrock Boy Scout facility in the area, with wooden shelters and a dining room, used Laurel Lake's beaches in 1922.[4] In 1921, "Laurel Lake Park" was one of 26 camps built by the Civilian Conservation Corps and maintained by the state for camping tourists,[5] and the public camp was still going strong in 1923.[6] By 1929, the Gettysburg Academy conducted week-end camps at Laurel Dam.[7] (A dam repair was performed in 1929.) Camp Lion was at the Laurel Dam in 1933.[8]
In 1947, sand was added to the lake's beach.[9]Gettysburg College used the park for football camp in both 1941 (at the 1941 Carlisle YMCA Camp site)[10] and in 1947.[11] Camp Thompson was at the lake in 1949[12] and 1953.[13]
A fire burned 7 acres near the lake in 1963. In 1965 the lake was closed due to contamination[14] and subsequently re-opened.
