The Tioga-Hammond Lakes Recreation Area is situated in north-central Pennsylvania, near the town of Tioga. It encompasses two reservoirs: Hammond Lake and Tioga Lake, which are main features for water-based recreation including boating, fishing, and swimming.

Covering over 2,400 acres combined (with approximately 680-acre Hammond Lake and about 498-acre Tiaga lake), this area was developed as a flood control project by the U.S Army Corps of Engineers with both lakes being impounded in the late-1970s. The recreation area officially opened to public use shortly thereafter.

Visitors can enjoy multiple facilities such as boat launches ramps on each lake; picnic areas; hiking trails like Overlook Trail that offers scenic views; campgrounds providing spots for tents or RV camping making it an ideal destination for outdoor enthusiasts seeking picturesque landscapes along with various recreational opportunities throughout all seasons.

The area now known as Tioga-Hammond Lakes Recreation Area has a history rooted in both natural and human activities. Prior to becoming a recreation destination, the land was primarily used for agriculture, timber harvesting, and coal mining.

Ownership of the lands changed hands multiple times over the years before being acquired by federal authorities. The U.S. Army Corps of Engineers took ownership with an aim to address flooding concerns along the Tioga River.

In response to devastating floods in Pennsylvania's northern regions during Hurricane Agnes in 1972, plans were made for flood control projects that included dam construction on local waterways such as Crooked Creek and Cowanesque River which resulted into creation of Hammond Lake (completed around 1979) while another project led to formation of nearby Tioga Lake.
