Grassy Island Creek is a tributary of the Lackawanna River in Lackawanna County, Pennsylvania, in the United States. It is approximately 4.4 miles (7.1 km) long and flows through Jefferson Township and Jessup. The watershed of the creek has an area of 5.42 square miles (14.0 km2). The lower reaches of the creek are impaired, but the upper reaches are not impaired. It is an intermittent stream during the summer, but its flow has been recorded as being as high as 116,553.21 gallons per minute. Some manganese, acidity, and alkalinity are also in the creek. It is in the Appalachian Mountain section of the ridge and valley physiographic province. The main rock formations in the creek's watershed are made of sandstone and interbedded sedimentary rocks. Some reservoirs are in the watershed at the boundary between the Pocono Formation and the Llewellyn Formation. The watershed of Grassy Island Creek is mainly forested, but there are also residential lands and abandoned mine lands. The creek is a source of flooding in Jessup. The remains of collieries such as the Sterrick Creek Colliery, the Mount Jessup Colliery, and the Pompey Colliery also occur in its vicinity. In 1996, the creek's channel failed, causing it to wash more than 30,000 cubic yards of culm into the Lackawanna River. In the 2000s, various channel repair efforts were carried out. A proposed natural gas-fired power plant intends to dump waste water into the creek.
