Lake Lackawanna

Lubber Run Fill is a fill on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between mileposts 50.1 and 50.5 in Byram Township, it was built between 1908 and 1911 by contractor Waltz & Reece Construction Company. It is 0.40 miles (0.64 km) long, has an average height of 64 feet (20 m), and a maximum height of 98 feet (30 m). Most of its 720,000 cubic yards (550500 m3) of fill material was excavated from the surrounding low-lying area. Lubber Run Fill is named for the Lubbers Run (the "s" was added to the stream's name sometime after the construction of the Cut-Off), which passes under the fill. A dam was built under the fill on the north side of the embankment, creating Dallis Pond, which flows into Lake Lackawanna. Lubber Run Fill supports a tangent (straight) section of right-of-way that permits speeds of 70 mph (113 km/h). It sits just east of Wharton Fill and just west of Bradbury Fill.A single track is to be relaid across the fill as part of the reactivation of the Cut-Off, which was abandoned in 1983. NJ Transit rail service is projected to begin no earlier than 2026.

The Byram Township School District is a comprehensive community public school district that serves students in pre-kindergarten through eighth grade from Byram Township, in Sussex County, New Jersey, United States.As of the 2017–18 school year, the district and its two schools had an enrollment of 843 students and 87.0 classroom teachers (on an FTE basis), for a student–teacher ratio of 9.7:1.The district is classified by the New Jersey Department of Education as being in District Factor Group "I", the second-highest of eight groupings.

Students from Byram Township had attended Sparta High School until 1974, when the Lenape Valley district was created.

Byram Township is a township in Sussex County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 8,028, a decrease of 322 (−3.9%) from the 2010 census count of 8,350, which in turn reflected an increase of 96 (+1.2%) from the 8,254 counted in the 2000 census.The municipality is known as the "Township of Lakes", as there are roughly two dozen lakes and ponds within its borders.

Punkhorn Creek is a small stream in the middle of Byram Township, Sussex County, New Jersey. It flows southwest from Lake Bottom, on the north side of and parallel with Amity Road, to Roseville Pond. It is a tributary of Lubbers Run, which is a tributary of the Musconetcong River. It joins Lubbers Run at Lake Lackawanna.

Wharton Fill is one of a number of fills (embankments) on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between mileposts 51.1 and 51.6 in Byram Township, the fill was constructed between 1908 and 1911 by contractor David W. Flickwir. The fill, which was created by placing fill material obtained by blasting with dynamite or other methods, is about 0.5 miles (0.64 km) long. Most of the material that was used to create Wharton Fill was excavated from the surrounding low-lying area through which Pumpkin Run runs; several of the borrow pits have since flooded and become ponds. Wharton Fill is located on a tangent (straight) section of right-of-way, permitting 80 mph (113 km/h), and is just west of Lubber Run Fill and just east of Roseville Tunnel. This section is scheduled to receive a single track as part of the reactivation of the line, which was abandoned in 1983. NJ Transit rail service is projected to begin no earlier than 2026. Wharton Fill is named for the Wharton Steel Company, from whom this section of right-of-way was acquired.

Byram Center is an unincorporated community and census-designated place (CDP) located in Byram Township, in Sussex County, in the U.S. state of New Jersey. As of the 2010 United States Census, the CDP's population was 90.

Roseville Tunnel is a 1,024-foot (312 m) two-track railroad tunnel on the Lackawanna Cut-Off in Byram Township, Sussex County, New Jersey. The tunnel is on a straight section of railroad between mileposts 51.6 and 51.8 (83 km), about 6 miles (9.7 km) north by northwest of Port Morris Junction. Operated for freight and passenger service from 1911 to 1979, it is undergoing work intended to return it to passenger service by 2026.

Colby Cut (also known as Roseville Cut) is one of a number of cuts on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between approximately mileposts 51.8 and 52.3 in Byram Township, the cut was constructed between 1908 and 1911 by contractor David W. Flickwir. (During construction, Lackawanna Railroad Chief Engineer, Lincoln Bush, would leave the railroad and join Flickwir's construction company to form the Flickwir & Bush construction company.) The cut, which was created by removing fill material obtained by blasting with dynamite or other methods, is 0.53 miles (0.85 km) long, has an average depth of 45 feet (14 m), and a maximum depth of 110 feet (34 m). The cut was the result of the removal of 462,342 cubic yards of fill material within this section. Colby Cut is named for F.G. Colby, from whom some of the land comprising the cut was acquired, west of what would be Roseville Tunnel. In March 1906, Colby, proposed to Lackawanna President William Truesdale for the railroad to locate a train station for the Cut-Off on his property near what was referred to as Roseville Lake (probably Wright's Pond, which is just east and north of the tunnel). Truesdale had Colby contact the chief engineer, Lincoln Bush, to investigate the idea, but the proposal appears to have gone no further. The cut-off's route was finalized on September 1, 1906. In the months prior, an alternate route was considered (Line "M") that would have proceeded north of where the tunnel would be located, avoiding the need for both the massive cut and the similarly massive Pequest Fill. Line M was rejected because its several-mile, curvaceous sweep to the south near Tranquility, NJ, would be operationally slower.Colby Cut is located on a tangent (straight) section of right-of-way, permitting 70 mph (110 km/h), and is just east of the Pequest Fill and just west of Roseville Tunnel. This section is scheduled to receive a single track as part of the reactivation of the line, which was abandoned in 1982 and the tracks removed in 1984. Colby Cut will be cleared as part of the Roseville Tunnel project by NJ Transit, whose rail service is projected to begin in 2026. The cut will have rockfall mitigation installed as well as improved drainage.
