The mouth of Prospect Park's watercourse is the artificial, 60-acre Prospect Lake (also known as Prospect Park Lake). Prospect Lake includes several islands and is home to over 20 species of fish. Every year, the lake hosts the R.H. Macy's Fishing Contest, a tradition that dates to 1947. Though NYC Parks generally allows licensed anglers to fish, it maintains a catch and release policy to prevent depletion of the fish population. In addition, visitors may explore the lake in kayaks and pedal boats, available at the LeFrak Center at Lakeside, or the "Independence," a replica of the original electric launch which took day-trippers around the lake in the 20th century. On the shore of the lake, there are several "rustic shelters" that provide scenic views of the water.
