the late 1800s, there was a sawmill on the creek in Shrewsbury Township, Lycoming County. A woolen mill was also built on the creek in Wolf Township, Lycoming County in 1842. An aqueduct carrying the West Branch Canal once crossed Muncy Creek. Historically, railroads ran parallel to Muncy Creek upstream from its mouth, as far as the community of Nordmont. There were also numerous railroad stations on the creek upstream from the community of Picture Rocks. The Reading Railroad also had a bridge over the creek in the past. The creek experienced severe flooding in 1889. In the early 1900s, many of the sewers in the community of Eagles Mere discharged into tributaries of Muncy Creek, such as Outlet Run. Sewage was also discharged into Muncy Creek in Hugesville. Additionally, in the early 1900s, the waters of Muncy Creek were contaminated with tannery waste products from Muncy Valley and also chemicals. For this reason, the creek was only used for power during this time. Additionally, a methyl alcohol plant, the Nordmont Chemical Works, discharged chemicals into the creek at Nordstown. Other major industries in the watershed in the early part of the 1900s included clay mines and furniture factories. Biology From its headwaters to a point upstream of its mouth, the drainage basin of Muncy Creek is designated as Exceptional Value and a Migratory Fishery. From this point downstream to the US Route 220 bridge at Muncy Valley, the creek's main stem is designated as a Coldwater Fishery and a Migratory Fishery. From this point downstream to its mouth, the main stem is designated as a Trout Stocked Fishery and a Migratory Fishery. Wild trout naturally reproduce in the creek from Trout Run downstream to its mouth. A total of 92 percent of assessed streams in the watershed of Muncy Creek are inhabited by trout. Of the inhabited streams, 82 percent are inhabited only by brook trout, nine percent are inhabited by only brown trout, and nine percent are inhabited by both brook trout and brown trout. A number of tributaries of the creek are designated as high-quality coldwater fisheries. These include Lick Run, Roaring Run, Rock Run, and Spring Run in Lycoming County and Big Run, Trout Run, and a number of others in Sullivan County. There are some forested areas in the floodplains of Muncy Creek in the United States Geological Survey quadrangle of Hughesville. The Natural Areas
