Lake Carl Blackwell, located approximately seven miles west of Stillwater, is a significant aquatic resource owned by Oklahoma State University. Constructed in 1937, the lake serves as the primary water source for the university and a backup supply for the City of Stillwater. It offers a variety of recreational activities, including hiking, fishing, picnicking and camping, with amenities such as equestrian trails, mountain bike trails and an 18-hole disc golf course. The lake also provides valuable habitat for freshwater fish, migratory waterfowl and shorebirds. Visitors can enjoy rustic cabin rentals, pavilion rentals for celebrations and a range of outdoor activities, making it a popular destination for relaxation and adventure. The lake is named for Carl Petty Blackwell Sr. (Nov. 5, 1886- March 4, 1937), who served as the dean of agriculture and director of the experimental station at the Oklahoma Agricultural and Mechanical College from 1928-37.
