It is designated as a High-Quality Coldwater Fishery and a Migratory Fishery above Interstate 476 and as a Coldwater Fishery and a Migratory Fishery below it. A section is also designated as Class A Wild Trout Waters. The stream's tributaries include Panther Creek, Plank Bridge Creek, Rattlesnake Creek, Green Run, Monument Creek, and Covey Swamp Creek. It has a relatively high level of water quality and is very slightly acidic, with a pH of 6.4 to 6.9. The upper reaches of the watershed of Spring Brook are mountainous and swampy.

in the Moosic Mountains. Sandstone, shale, and some coal are present in the vicinity of the stream. It has been channelized in a concrete channel for part of its length and is the main source of flooding in Spring Brook Township, Lackawanna County. The stream is the second-largest tributary of the Lackawanna River. Reservoirs on Spring Brook include the Spring Brook Intake, the Nesbitt Reservoir, the Watres Reservoir. There are three dams on the stream. The watershed is mainly forested, with only a small amount of urban land. In the past, industries in the watershed of Spring Brook included timbering, coal mining, and agriculture. Two railroads also passed through the watershed in the early 1900s, at least one of which was established by the 1880s. The stream's watershed has served as a water supply since at least the early 1900s and still serves as a water supply for the Lackawanna Valley. Several bridges have also been constructed across the stream in the 20th century. The stream has been part of several studies since 1970. Part of its length is navigable by kayaking, paddling, and rafting.

Course

Spring Brook begins near Interstate 380 in Covington Township, Lackawanna County. It flows south for a short distance before meandering west for a few miles, crossing Interstate 380 and entering Spring Brook Township. The stream then turns south for several tenths of a mile before turning northwest for several tenths of a mile. It turns southwest before turning north-northwest and flowing around The Hogback. On the northern side of that hill, the stream turns south and then northwest, entering the Watres Reservoir. The stream exits the reservoir on its western side and flows northwest for a few miles, passing Pinnacle Hill and receiving the tributaries Panther Creek and Plank Bridge Creek from the left. It eventually bends east and enters the Nesbitt Reservoir after crossing

. Here, it receives the tributary Rattlesnake Creek from the right and flows between high hills. On the northern side of the reservoir, the stream flows north, receiving the tributary Green Run from the right before turning west-southwest. A few miles further downstream, it passes through the Spring Brook Intake before exiting Lackawanna County. Upon exiting Lackawanna County, Spring Brook enters Pittston Township, Luzerne County. It receives the tributary Monument Creek from the left and turns north-northwest for a few miles, flowing alongside Pennsylvania Route 502. On this stretch, it leaves behind the hills that it flows through, crosses Pennsylvania Route 502, and exits Luzerne County. Upon exiting Luzerne County, the stream enters Moosic, Lackawanna County and continues flowing north-northwest and receives the tributary Covey Swamp Creek from the right. The stream then turns west-southwest for a short distance before turning south and then west, crossing

Hydrology

Spring Brook experiences noticeable flow loss. As of 2009, it has high levels of sodium and alkalinity. Pittson Township and the borough of Moosic have permits to discharge stormwater into it. However, the

and habitat quality of the stream are relatively unimpacted. The stream has relatively high water quality even where it flows through a concrete channel. In a study by the Susquehanna River Basin Commission, it was found not to fail any water quality standards either during base flow or storm flow conditions. However, a study from the previous year found concentrations of sodium and alkalinity exceeding the threshold for concern. In the early 1900s, Spring Brook was a clear stream in its upper reaches. However, by the time it reached the property of the Du Pont Powder Company, it was affected by slush pumped into it by the Pennsylvania Coal Company. Between 1971 and 1990, the

Recreation

A trail known as the Spring Brook / Wilkes-Barre and Eastern Greenway was proposed in the Lackawanna River Watershed Conservation Plan in 2001. There are plans for trails on the flood levee at the stream's mouth and on the old Wilkes-Barre and Eastern Railroad corridor. A stretch of at least of Spring Brook are navigable by kayaking, paddling, or rafting. This stretch runs from the Nesbitt Reservoir to Moosic. The difficulty of the stream ranges from Class II to Class IV. Spring Brook is an approved trout stream. In 1996, it was opened for trout fishing on April 29.
