Course
Trout Brook begins in a pond or small lake in West Abington Township, to the northeast of Wilbur Hill. It flows northwest for a short distance before turning north for several tenths of a mile, passing through one pond or small lake and entering another, where it receives an unnamed tributary from the right. The stream then turns west-northwest for a short distance before turning north-northwest and passing through two more lakes and receiving an unnamed tributary from the left and two more from the right. The stream then turns northwest for several tenths of a mile before exiting West Abington Township and Lackawanna County.

Upon exiting Lackawanna County, Trout Brook enters Clinton Township, Wyoming County. It heads west-northwest for several tenths of a mile, receiving two unnamed tributaries from the left and one from the right, and then turns southwest.
