Short of the Shore, swimming options that don't involve pools are limited around Philadelphia. The two largest bodies of water, the Schuylkill and the Delaware Rivers, don't have recreational swimming areas, and people drown in both every summer. In 2007, the Schuylkill River National and State Heritage Area studied whether swimming could work at a dozen sites on both rivers. Venice Island, on the Schuylkill near Manayunk, was identified as a potential swimming area, along with Pleasant Hill Park, on the Delaware, in Northeast Philly. Neither suggestion has been implemented.
