From the northern end of that reservoir, it flows north for a short distance and crosses US Route 6 before turning west-northwest.

Over the next several tenths of a mile, the stream gradually turns northwest before crossing a highway and reaching its confluence with the Lackawanna River.

[1] Racket Brook joins the Lackawanna River 29.44 miles (47.38 km) upriver of its mouth.

[4] However, it experiences some minor flow loss to mine pools in its lower reaches.

[5] In the early 1900s, Racket Brook was found to be a clear stream from the Brownell Reservoir.

However, its banks were lined with culm from the Racket Brook Colliery to a point 0.5 miles (0.80 km) downstream.

[7] At its mouth, the peak annual discharge of Racket Brook has a 10 percent chance of reaching 650 cubic feet per second.

[3] A coal bed with a thickness of 3.5 feet (1.1 m) is located in the vicinity of Racket Brook.

[2] The mouth of the steam is in the United States Geological Survey quadrangle of Carbondale.

The lower reaches of the watershed are in commercial, residential, and urban parts of Carbondale.

[3] Racket Brook was entered into the Geographic Names Information System on August 2, 1979.

[3] The mining was done by William and Maurice Wurts, founders of the Delaware and Hudson Enterprise, which singlehandedly allowed the anthracite industry in the mid and upper Lackawanna River watershed to develop.

The first D&H gravity railroad inclined plane began operations at the mouth of the stream in 1829.

The Lackawanna River Watershed Conservation Plan proposed a Heritage Landing at this site.

[14] In the early 2000s, the Lackawanna River Watershed Conservation Plan proposed a greenway/connecting trail along Racket Brook.

[15] Wild trout naturally reproduce in the stream from the Brownell Reservoir downstream to the mouth, a distance of 1.60 miles (2.57 km).

[16] Ridgetop scrub oak/pitch pine barrens occur in the upper reaches of the watershed of Racket Brook.
