Panther Hollow Lake, artificial lake in Schenley Park, Pittsburgh, United States

Panther Hollow Lake is a human-made lake in Schenley Park in Pittsburgh, Pennsylvania. It was originally 600 feet long and 275 feet wide, but sediment has left most of it less than 4 feet deep. Two streams, Phipps Run and Panther Hollow Run, feed the lake.

Panther Hollow Lake was built in 1892 during the early development of Schenley Park, when it measured about 600 feet long and 275 feet wide. By 1907 sediment had left it only 6 inches deep in most places, so in 1909 it was expanded and rebuilt with a concrete lining and a new boathouse. Mayor David L. Lawrence ordered a full draining and rebuilding of the walls in 1957, and the boathouse was demolished in 1979.

The name comes from the Panther Hollow valley the lake sits in. Rowing and ice skating drew crowds here from the 1890s, and skating continued until the 1970s. The boathouse that served these pastimes was demolished in 1979, after which the lake fell out of general public use.

The area is easy to access on foot with simple paths to explore. Visitors should know that the paths are usable year-round and weather can change quickly, so appropriate clothing is recommended.

Panther Hollow Lake drains the 300-acre Panther Hollow Watershed, which covers parts of Schenley Park and Squirrel Hill, and sends its water to the Monongahela River through Four Mile Run. Two streams, Phipps Run and Panther Hollow Run, feed it. The streams of Squirrel Hill itself are now buried and flow into the city sewers instead of the lake.
