Historic Saylor Grove
Stormwater runoff from about 150 acres of developed land drains through Saylor Grove, located within Monoshone Creek Watershed. The original inhabitants of this land were the Lenape people, from whom the name "Monoshone" originates. In the Lenape language, "Monoshone" means 'Stream where we gather grasses.'

Industrialization between 1690 and the mid-1800s brought Mills and quarries to the edge of Saylor Grove. The intense use of the creek to carry away industrial and human waste damaged all aspects of the Monoshone Creek Watershed.

Since the late 1800s, residential development has forced increasing volumes of polluted stormwater runoff into Monoshone Creek. Today the Monoshone is considered "impaired"-- polluted and unable to support the plants and animals once found there. There are a number of ways, however, to improve Monoshone Creek

Queen Lane, the health of the entire Wissahickon Creek Watershed, including the Monoshone, is important to all of its citizens.

Why a Wetland to Restore the Creek?
Wetlands clean water, replenish groundwater, reduce flooding risk, and provide places for wildlife to live. Saylor Grove Wetland helps to slow down and filter polluted stormwater runoff before it enters Monoshone Creek.

"I hope the Grove will thrive and bring beauty into the lives of many men, women and children in the days to come."
Harold D. Saylor, 1974
Judge Saylor (1892-1981) served as a Fairmount Park Commissioner for nearly twenty-five years. Sailor Grove was named in his honor to recognize his lifelong commitment to conservation of the region's natural resources.
