## History

Collins Creek was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1172217.
A storm in 1955 caused high waters on Collins Creek. However, there was little flooding in Pittston Township during that storm. In 1990, a tanker truck spilled 8000 gallons of gasoline in the area, causing emergency operations to be performed in the watershed of the creek. In 2002, the replacement of a bridge carrying Interstate 81 over the creek in Dupont was authorized for $1,100,000. Collins Creek and Lidy Creek were subjected to a restoration project that was approved in 2007. It was carried out by Sikora Brothers Paving Co. for $46,709. The Federal Emergency Management Agency funded $45,000.
