Muncy Creek Township is one of the oldest and, from a historical viewpoint, one of the most interesting in Lycoming County. It was set off from Muncy Township, the mother of all those lying north and east of the river, in 1797, two years after the erection of Lycoming as a separate county. Within its borders some of the earliest settlements in the West Branch Valley were made. It is surrounded on the north by the river and Muncy and Wolf townships, on the east by Wolf and Moreland townships, on the south by Montour and Northumberland counties and on the west by the river which separates it from Clinton Township.It is well watered, both the Big and Little Muncy creeks flowing through it. Glade Run also traverses it from south to north. It is the twentieth in size in the county and contains 12,800 acres. It lies on the east side of the great bend in the river where it sweeps majestically around the base of Bald Eagle mountain and the land in the immediate vicinity of this bend is of unsurpassed fertility. Close to the river, a short distance below the borough of Muncy, is located the famous Warrior Spring celebrated in song and story and which figured largely in many of the old Indian legends of the neighborhood. It was a favorite gathering place for the Indian tribes of that section and has been a well known landmark for more than a century and a half.

Near the spring is located the little settlement known as Port Penn which at one time possessed very considerable importance. It is one of the oldest hamlets in the county and near it formerly stood a great elm tree under the shade of which the Indians of the valley were accustomed to hold their great councils. During the old canal days Port Penn was the stopping place for the packet boats and boasted of having one of the best taverns along the line of the canal. It also had important boat yards. It was a noted place during the building of the canal and especially the Muncy dam, which was thrown across the river about three miles below for the purpose of flooding the canal level from there to Shamokin dam below Sunbury. Muncy dam was one of the most substantial pieces of engineering work in the state at the time of its construction and cost a large sum of money. Even the towing path which extended around the base of the Muncy hills from Port Penn to the dam cost the state the very considerable sum of $15,369.06.

The stretch of water from Port Penn to Muncy dam was a very important place during the old rafting days on the river. Scores of immense timber rafts tied up there, each waiting its turn to run the chute in the dam. There was a famous hotel of unsavory reputation located just above the dam which was a welcome resort for the red-shirted lumbermen while waiting their chance to "shoot the chute." Gambling, drinking, prize fighting and other amusements of a like character were common occurrences. At this point there was also located at one time one of the most dangerous gangs of counterfeiters in the country. They made their spurious coin in a cabin back of the hotel and unloaded it on the rivermen. The gang eluded the officers of the law for a long time, but was finally run down, convicted and sent to prison. This place was also the scene of a serious riot during the construction of the canal which resulted in the killing of several men. Muncy dam has always been a favorite place for fishing and there is, perhaps even now, no place on the river where one can find better sport. While the canal was still in existence it was a famous place for eels. Baskets were placed at the head of the canal where the water flowed into it and as many as eighteen hundred eels have been known to have been taken in a single night.

Muncy borough is located within the limits of Muncy Creek Township and, aside from this, and the little hamlet of Port Penn, there is only one village in the township, Clarkstown. This is located in a beautiful cove which opens into the Muncy Valley along the bank of Little Muncy Creek, a short distance above its confluence with the Big Muncy. Clarkstown is a very old settlement dating back to the eighteenth century. The early settlers were nearly all Germans of a sturdy character who soon became prosperous and some of them comparatively wealthy. In the early days the first improvements that were made were the building of grist mills, carding mills and churches and we find that Isaac Walton built the first grist mill on Muncy Creek near Clarkstown as early as 1797 and John Opp a wool carding and cloth dressing mill in 1812. Both of these were a great convenience to the early settlers.

The first church edifice to be erected within the limits of what is now Lycoming County was the Immanuel Lutheran at Clarkstown which was finished in the year 1791. There may have been earlier church societies, but this is the first church building of which there is any record. It was unusually large for that period, having a seating capacity of about five hundred. It was built of logs and then weatherboarded. There were galleries around three sides of the auditorium and a "stem glass" pulpit with a large sounding board above it. The backs of the pews were as high as a person’s head. Although it was erected entirely by the Lutherans, other denominations were permitted to use it. The church records were all kept in German down to the year 1882. It has twice been rebuilt or enlarged. In 1882 a stone addition was erected which became the main church edifice and in 1871 it was entirely remodelled. The burying ground adjacent to the church is one of the quaintest and most interesting in the county and contains the remains of some of the most prominent of the early settlers. The whole surrounding country is filled with historic interest of the Indian and Revolutionary period.

Most of the land in Muncy Creek Township is very fertile and productive although some of it is extremely hilly. There are some valuable deposits of minerals, noticeably a kind of silicic clay which is extensively used for paint fillers and the manufacture of some varieties of coach paint. Opps, near the Muncy Township line is the only postoffice in the township. In 1920 it had a population of 1,283.
