The state began acquiring land for the creation of Groton State Forest in the 1910s, but much of it was occupied by leaseholders. It was not until the 1920s that most of the leases were closed out, and the state did not have the funds to develop the forest for recreation, although it made plans for such facilities. When the
Civilian Conservation Corps was established by the federal government in the 1930s, the state used its crews and funding to develop this state park and others. The CCC crews that worked on the various state parks (now numbering seven) in Groton State Forest were based at a camp whose foundational remnants remain in this park. These crews built out the road network serving the campground and the picnic areas at Lake Osmore and Owl's Head, although the latter two were at first separately administered. They built a small campground (now eight sites within Area B of the present campground), and the picnic facilities at Lake Osmore and Owl's Head, as well as the small stone observation tower on Owl's Head. They were also responsible for cutting much of the early trail network through the northern part of the forest, and building part of the maintenance facilities used by the state forest today. Because of the state of preservation of these areas, the park was listed on the
National Register of Historic Places in 2002. ==See also==
