:Lock Haven, Pennsylvania

The earliest settlers in Pennsylvania arrived from Asia between 12000 BCE and 8000 BCE, when the glaciers of the Pleistocene Ice Age were receding. Fluted point spearheads from this era, known as the Paleo-Indian Period, have been found in most parts of the state.{{cite web | last = Pennsylvania Historical and Museum Commission | title = Pennsylvania Archaeology: An Introduction | publisher = Commonwealth of Pennsylvania | url = http://www.phmc.state.pa.us/ppet/archaeology/page1.asp?secid=31 | access-date = November 11, 2009 |archive-url = https://web.archive.org/web/20080625100450/http://www.phmc.state.pa.us/ppet/archaeology/page1.asp?secid=31 |archive-date = June 25, 2008}} Archeological discoveries at the Memorial Park Site 36Cn164 near the confluence of the West Branch Susquehanna River and Bald Eagle Creek collectively span about 8,000 years and represent every major prehistoric period from the Middle Archaic to the Late Woodland period.{{sfn|Schuldenrein|Vento|1994|p=1|loc=chapter 1}} Prehistoric cultural periods over that span included the Middle Archaic starting at 6500 BCE; the Late Archaic starting at 3000 BCE; the Early Woodland starting at 1000 BCE; the Middle Woodland starting at 0 CE; and the Late Woodland starting at 900 CE.{{sfn|Richter|2002|p=4}} First contact with Europeans occurred in Pennsylvania between 1500 and 1600 CE.{{sfn|Richter|2002|p=4}}At the time of first contact, several tribes lived in what later became Pennsylvania.

In the early 18th century, a tribal confederacy known as the Six Nations of the Iroquois, headquartered in New York, ruled the Indian (Native American) tribes of Pennsylvania, including those who lived near what would become Lock Haven. Indian settlements in the area included three Munsee villages on the {{convert|325|acre|km2|adj=on}} Great Island in the West Branch Susquehanna River at the mouth of Bald Eagle Creek. Four Indian trails, the Great Island Path, the Great Shamokin Path, the Bald Eagle Creek Path, and the Sinnemahoning Path, crossed the island, and a fifth, Logan's Path, met Bald Eagle Creek Path a few miles upstream near the mouth of Fishing Creek.{{sfn|Wallace|1987|p=frontispiece (map)}} During the French and Indian War (1754–63), colonial militiamen on the Kittanning Expedition destroyed Munsee property on the Great Island and along the West Branch. By 1763, the Munsee had abandoned their island villages and other villages in the area.{{sfn|Miller|1966|p=4}}The earliest recorded inhabitants of the West Branch Susquehanna River valley were the Susquehannocks, but they were wiped out by disease and warfare with the Iroquois, and the few members left moved west or were assimilated into other tribes by 1675. After that the Iroquois, who were the nominal rulers of the land but mostly lived in New York to the north, invited tribes displaced by European settlers to move into the region. These included the Lenape (Delaware), Shawnee, and others. Generally, they moved west into the Ohio River Valley. For more information see Wallace, Paul A.W. (2005).

With the signing of the first Treaty of Fort Stanwix in 1768, the British gained control from the Iroquois of lands south of the West Branch. However, European settlers continued to appropriate land, including tracts in and near the future site of Lock Haven, not covered by the treaty.

In 1769, Cleary Campbell, the first European settler in the area, built a log cabin near the present site of Lock Haven University of Pennsylvania, and by 1773 William Reed, another settler, had built a cabin surrounded by a stockade and called it Reed's Fort.{{sfn|Miller|1966|pp=18, 23}} It was the westernmost of 11 mostly primitive forts along the West Branch; Fort Augusta, located by the confluence of the East (or North) and West branches of the Susquehanna at what is now Sunbury, was the easternmost and most defensible. In response to settler incursions, and encouraged by the British during the American Revolution (1775–83), Indians attacked colonists and their settlements along the West Branch. Fort Reed and the other European settlements in the area were temporarily abandoned in 1778 during a general evacuation known as the Big Runaway. Hundreds of people fled along the river to Fort Augusta, about {{convert|50|mi|km|sigfig=1}} from Fort Reed; some did not return for five years.{{sfn|Miller|1966|p=28}} In 1784, the second Treaty of Fort Stanwix, between the Iroquois and the United States, transferred most of the remaining Indian territory in Pennsylvania, including what would become Lock Haven, to the state. The U.S. acquired the last remaining tract, the Erie Triangle, through a separate treaty and sold it to Pennsylvania in 1792.{{cite book|last = Day | first = Sherman | title = Historical collections of the State of Pennsylvania |url = https://books.google.com/books?id=ePzzh7IIPjAC&q=treaty%20of%20fort%20stanwix%201784&pg=PA449 | publisher = George W.

Lock Haven was laid out as a town in 1833, and it became the county seat in 1839, when Clinton County was created out of parts of Lycoming and Centre counties.{{sfn|Linn|1883|p=489}} Incorporated as a borough in 1840 and as a city in 1870,{{cite web | title = Clinton County – 7th class |publisher = Pennsylvania Historical and Museum Commission |url =http://www.phmc.state.pa.us/BAH/DAM/counties/pdfs/Clinton.pdf |access-date = November 27, 2009|archive-url=https://web.archive.org/web/20150514223232/http://www.phmc.state.pa.us/BAH/DAM/counties/pdfs/Clinton.pdf|archive-date=May 14, 2015|url-status=live}} Lock Haven prospered in the 19th century largely because of timber and transportation. The forests of Clinton County and counties upriver held a huge supply of white pine and hemlock as well as oak, ash, maple, poplar, cherry, beech, and magnolia. The wood was used locally for such things as frame houses, shingles, canal boats, and wooden bridges, and whole logs were floated to Chesapeake Bay and on to Baltimore, to make spars for ships. Log driving and log rafting, competing forms of transporting logs to sawmills, began along the West Branch around 1800. By 1830, slightly before the founding of the town, the lumber industry was well established.{{sfn|Miller|1966|pp=109–111}}

The West Branch Canal, which opened in 1834, ran {{convert|73|mi|km|0}} from Northumberland to Farrandsville, about {{convert|5|mi|km|0}} upstream from Lock Haven. A state-funded extension called the Bald Eagle Cut ran from the West Branch through Lock Haven and Flemington to Bald Eagle Creek. A privately funded extension, the Bald Eagle and Spring Creek Navigation, eventually reached Bellefonte, {{convert|24|mi|km|0}} upstream. Lock Haven's founder, Jeremiah Church, and his brother, Willard, chose the town site in 1833 partly because of the river, the creek, and the canal. Church named the town Lock Haven because it had a canal lock and because it was a haven for loggers, boatmen, and other travelers. Over the next quarter century, canal boats {{convert|12|ft|m|0}} wide and {{convert|80|ft|m|0}} long carried passengers and mail as well as cargo such as coal, ashes for lye and soap, firewood, food, furniture, dry goods, and clothing. A rapid increase in Lock Haven's population (to 830 by 1850){{sfn|Wagner|1979|p=42}} followed the opening of the canal.{{sfn|Miller|1966|pp=44–46}}

A Lock Haven log boom, smaller than but otherwise similar to the Susquehanna Boom at Williamsport, was constructed in 1849. Large cribs of timbers weighted with tons of stone were arranged in the pool behind the Dunnstown Dam, named for a settlement on the shore opposite Lock Haven. The piers, about {{convert|150|ft|m|0}} from one another, stretched in a line from the dam to a point {{convert|3|mi|km|0}} upriver. Connected by timbers shackled together with iron yokes and rings, the piers anchored an enclosure into which the river current forced floating logs. Workers called boom rats sorted the captured logs, branded like cattle, for delivery to sawmills and other owners. Lock Haven became the lumber center of Clinton County and the site of many businesses related to forest products.{{sfn|Miller|1966|pp=111–119}}

The Sunbury and Erie Railroad, renamed the Philadelphia and Erie Railroad in 1861, reached Lock Haven in 1859, and with it came a building boom. Hoping that the area's coal, iron ore, white pine, and high-quality clay would produce significant future wealth, railroad investors led by Christopher and John Fallon financed a line to Lock Haven. On the strength of the railroad's potential value to the city, local residents had invested heavily in housing, building large homes between 1854 and 1856. Although the Fallons' coal and iron ventures failed, Gothic Revival, Greek Revival, and Italianate mansions and commercial buildings such as the Fallon House, a large hotel, remained, and the railroad provided a new mode of transport for the ongoing timber era. A second rail line, the Bald Eagle Valley Railroad, originally organized as the Tyrone and Lock Haven Railroad and completed in the 1860s, linked Lock Haven to Tyrone, {{convert|56|mi|km|0}} to the southwest. The two rail lines soon became part of the network controlled by the Pennsylvania Railroad.{{sfn|Wagner|1979|pp=9–60}}

During the era of log floating, logjams sometimes occurred when logs struck an obstacle. Log rafts floating down the West Branch had to pass through chutes in canal dams. The rafts were commonly {{convert|28|ft|m|0}} wide—narrow enough to pass through the chutes—and {{convert|150|ft|m|0}} to {{convert|200|ft|m|0}} long.{{cite journal | last = Theiss | first = Lewis Edwin | title = Lumbering in Penn's Woods | journal = Pennsylvania History: A Journal of Mid-Atlantic Studies | volume = 19 | issue = 4 | pages = 397–412 | publisher = Pennsylvania Historical Association | location = University Park, Pa. |date=October 1952 | url = http://journals.psu.edu/phj/article/view/22227/21996| format = PDF | id = psu.ph/1133209642 | access-date = February 3, 2008|archive-url=https://web.archive.org/web/20150616050600/https://journals.psu.edu/phj/article/view/22227/21996|archive-date=June 16, 2015|url-status=live}} In 1874, a large raft got wedged in the chute of the Dunnstown Dam and caused a jam that blocked the channel from bank to bank with a pile of logs {{convert|16|ft|m|0}} high. The jam eventually trapped another 200 log rafts, and 2 canal boats, The Mammoth of Newport and The Sarah Dunbar.{{sfn|Miller|1966|pp=119–120}}

In terms of volume, the peak of the lumber era in Pennsylvania arrived in about 1885, when {{nowrap|1.9 million logs}} went through the boom at Williamsport. These logs produced a total of {{convert|226|e6board feet|e3m3|abbr=off|lk=on}} of sawed lumber. After that, production steadily declined throughout the state. Lock Haven's timber business was also affected by flooding, which badly damaged the canals and destroyed the log boom in 1889.{{sfn|Miller|1966|p=59}}

The Central State Normal School, established to train teachers for central Pennsylvania, held its first classes in 1877 at a site overlooking the West Branch Susquehanna River. The small school, with enrollments below 150 until the 1940s, eventually became Lock Haven University of Pennsylvania.{{cite web | title = Lock Haven University: A Brief History | publisher = Lock Haven University | url = http://www.lhup.edu/library2/archive/briefhistory.htm | access-date = October 13, 2009|archive-url=https://web.archive.org/web/20120217095059/http://www.lhup.edu/library2/archive/briefhistory.htm|archive-date=February 17, 2012}} In the early 1880s, the New York and Pennsylvania Paper Mill in Castanea Township near Flemington began paper production on the site of a former sawmill; the paper mill remained a large employer until the end of the 20th century.

As older forms of transportation such as the canal boat disappeared, new forms arose. One of these, the electric trolley, began operation in Lock Haven in 1894. The Lock Haven Electric Railway, managed by the Lock Haven Traction Company and after 1900 by the Susquehanna Traction Company, ran passenger trolleys between Lock Haven and Mill Hall, about {{convert|3|mi|km|0}} to the west. The trolley line extended from the Philadelphia and Erie Railroad station in Lock Haven to a station of the Central Railroad of Pennsylvania, which served Mill Hall. The route went through Lock Haven's downtown, close to the Normal School, across town to the trolley car barn on the southwest edge of the city, through Flemington, over the Bald Eagle Canal and Bald Eagle Creek, and on to Mill Hall via what was then known as the Lock Haven, Bellefonte, and Nittany Valley Turnpike. Plans to extend the line from Mill Hall to Salona, {{convert|3|mi|km|0}} south of Mill Hall, and to Avis {{convert|10|mi|km|0}} northeast of Lock Haven, were never carried out, and the line remained unconnected to other trolley lines. The system, always financially marginal, declined after World War I. Losing business to automobiles and buses, it ceased operations around 1930.{{sfn|Shieck|Cox|1978|pp=81–92}}

William T. Piper Sr. built the Piper Aircraft Corporation factory in Lock Haven in 1937 after the company's Taylor Aircraft manufacturing plant in Bradford, Pennsylvania, was destroyed by fire. The factory began operations in a building that once housed a silk mill.{{cite web |author=City of Lock Haven Planning Office |author2=Clinton County Comprehensive Planning Advisory Committee |author3=Gannett Fleming, Inc. |author4=Larson Design Group | title = Comprehensive Plan Update (2005) | publisher = City of Lock Haven | url =http://lockhavenpa.gov/wp-content/uploads/2015/01/2005_comp_plan.pdf |archive-url=https://web.archive.org/web/20150420184323/http://lockhavenpa.gov/wp-content/uploads/2015/01/2005_comp_plan.pdf|url-status=live|archive-date=April 20, 2015| access-date = September 21, 2007}} As the company grew, the original factory expanded to include engineering and office buildings. Piper remained in the city until 1984, when its new owner, Lear-Siegler, moved production to Vero Beach, Florida. The Clinton County Historical Society opened the Piper Aviation Museum at the site of the former factory in 1985, and 10 years later the museum became an independent organization.

The state of Pennsylvania acquired Central State Normal School in 1915 and renamed it Lock Haven State Teachers College in 1927. Between 1942 and 1970, the student population grew from 146 to more than 2,300; the number of teaching faculty rose from 25 to 170, and the college carried out a large building program. The school's name was changed to Lock Haven State College in 1960, and its emphasis shifted to include the humanities, fine arts, mathematics, and social sciences, as well as teacher education. Becoming Lock Haven University of Pennsylvania in 1983, it opened a branch campus in Clearfield, {{convert|48|mi|km|0}} west of Lock Haven, in 1989.

An {{convert|8|acre|ha|adj=on}} industrial area in Castanea Township adjacent to Lock Haven was placed on the National Priorities List of uncontrolled hazardous waste sites, commonly referred to as Superfund sites, in 1982. Drake Chemical, which went bankrupt in 1981, made ingredients for pesticides and other compounds at the site from the 1960s to 1981. Starting in 1982, the United States Environmental Protection Agency began a clean-up of contaminated containers, buildings, and soils at the site and by the late 1990s had replaced the soils. Equipment to treat contaminated groundwater at the site was installed in 2000 and continues to operate.{{cite web | title = Mid-Atlantic Superfund: Drake Chemical: Current Site Information | publisher = U.S. Environmental Protection Agency | url = http://www.epa.gov/reg3hwmd/npl/PAD003058047.htm | access-date = October 18, 2007|archive-url=https://web.archive.org/web/20150514224655/http://www.epa.gov/reg3hwmd/npl/PAD003058047.htm|archive-date=May 14, 2015|url-status=live}}

Karnish Instruments was a privately-owned company in Lock Haven that manufactured aircraft parts such as dials and pointers.{{Cite web |title=Karnish Instruments, Inc. |url=https://opencorporates.com/companies/us_pa/184137 |access-date=April 16, 2025|website=opencorporates.com}} They coated many of their products with radioactive paint containing radium-266, allowing them to glow in the dark.

=== Floods ===

Pennsylvania's streams have frequently flooded. According to William H. Shank, the Native Americans of Pennsylvania warned white settlers that great floods occurred on the Delaware and Susquehanna rivers every 14 years. Shank tested this idea by tabulating the highest floods on record at key points throughout the state over a 200-year period and found that a major flood had occurred, on average, once every 25 years between 1784 and 1972. Big floods recorded at Harrisburg, on the main stem of the Susquehanna about {{convert|120|mi|km|sigfig=2}} downstream from Lock Haven, occurred in 1784, 1865, 1889, 1894, 1902, 1936, and 1972. Readings from the Williamsport stream gauge, {{convert|24|mi|km|0}} below Lock Haven on the West Branch of the Susquehanna, showed major flooding between 1889 and 1972 in the same years as the Harrisburg station; in addition, a large flood occurred on the West Branch at Williamsport in 1946.{{sfn|Shank|1972|pp=10–13}} Estimated flood-crest readings between 1847 and 1979—based on data from the National Weather Service flood gauge at Lock Haven—show that flooding likely occurred in the city 19 times in 132 years.{{sfn|Schuldenrein|Vento|1994|pp=4–5|loc=chapter 2, table 1}} The biggest flood occurred on March 18, 1936, when the river crested at {{convert|32.3|ft|m}}, which was about {{convert|11|ft|m}} above the flood stage of {{convert|21|ft|m}}.{{sfn|Schuldenrein|Vento|1994|pp=4–5|loc=chapter 2, table 1}}

The third biggest flood, cresting at {{convert|29.8|ft|m}} in Lock Haven, occurred on June 1, 1889,{{sfn|Schuldenrein|Vento|1994|pp=4–5|loc=chapter 2, table 1}} and coincided with the Johnstown Flood. The flood demolished Lock Haven's log boom, and millions of feet of stored timber were swept away.{{sfn|Shank|1972|pp=22–23}} The flood damaged the canals, which were subsequently abandoned, and destroyed the last of the canal boats based in the city.{{sfn|Miller|1966|p=59}}

The most damaging Lock Haven flood was caused by the remnants of Hurricane Agnes in 1972. The storm, just below hurricane strength when it reached the region, made landfall on June 22 near New York City. Agnes merged with a non-tropical low on June 23, and the combined system affected the northeastern United States until June 25. The combination produced widespread rains of {{convert|6|to|12|in|mm|0}} with local amounts up to {{convert|19|in|mm|0}} in western Schuylkill County, about {{convert|75|mi|km|0}} southeast of Lock Haven.{{cite web| url =http://www.wpc.ncep.noaa.gov/tropical/rain/agnes1972.html|title =Hurricane Agnes – June 14–25, 1972 | publisher=National Oceanic and Atmospheric Administration (NOAA)| access-date=September 16, 2007|archive-url=https://web.archive.org/web/20150209162410/http://www.wpc.ncep.noaa.gov/tropical/rain/agnes1972.html|archive-date=February 9, 2015|url-status=live}} At Lock Haven, the river crested on June 23 at {{convert|31.3|ft|m}}, second only to the 1936 crest.{{sfn|Schuldenrein|Vento|1994|pp=4–5|loc=chapter 2, table 1}} The flood greatly damaged the paper mill and Piper Aircraft.

In 1992, federal, state, and local governments began construction of barriers to protect the city. The project included a levee of {{convert|36000|ft|m|sigfig=2}} and a flood wall of {{convert|1000|ft|m|sigfig=1}} along the Susquehanna River and Bald Eagle Creek, closure structures, retention basins, a pumping station, and some relocation of roads and buildings.

Lock Haven is at {{convert|561|ft|m|0}} above sea level near the confluence of Bald Eagle Creek and the West Branch of the Susquehanna River in north-central Pennsylvania. The city is approximately {{convert|200|mi|km|-1}} by highway northwest of Philadelphia and {{convert|175|mi|km|-1}} northeast of Pittsburgh. U.S. Route 220, a major transportation corridor, skirts the city on its southern edge, intersecting with Pennsylvania Route 120, which passes through the city and connects it with Renovo in northern Clinton County. Other highways entering Lock Haven include state routes 150, which connects to Avis, and 664.{{cite map |publisher = Rand McNally & Company |title = The Road Atlas |edition = 2008 |section = 86–89 |isbn = 0-528-93961-0 }}

The city and nearby smaller communities, including Castanea, Dunnstown, Flemington, and Mill Hall, are mainly at valley level in the Ridge-and-Valley Appalachians, a mountain belt characterized by long, even valleys running between long continuous ridges. Bald Eagle Mountain, one of these ridges, runs parallel to Bald Eagle Creek on the south side of the city. Upstream of the confluence with Bald Eagle Creek, the West Branch Susquehanna River drains part of the Allegheny Plateau, a region of dissected highlands (also called the "Deep Valleys Section") generally north of the city.{{cite web | title = Landforms of Pennsylvania from Map 13, Physiographic Provinces of Pennsylvania | publisher = Pennsylvania Department of Natural Resources and Conservation | url = http://www.dcnr.state.pa.us/cs/groups/public/documents/document/dcnr_016202.pdf| access-date = April 21, 2015|archive-url=https://web.archive.org/web/20150421172859/http://www.dcnr.state.pa.us/cs/groups/public/documents/document/dcnr_016202.pdf|archive-date=April 21, 2015}}{{cite web | title = National Register of Historic Places Inventory—Nomination Form: Memorial Park Site, 36Cn164 | publisher = United States National Park Service| url = https://www.dot7.state.pa.us/ce_imagery/phmc_scans/H001002_01H.pdf | access-date = November 12, 2009|archive-url=https://web.archive.org/web/20141020222616/https://www.dot7.state.pa.us/ce_imagery/phmc_scans/H001002_01H.pdf|archive-date=October 20, 2014}} The geologic formations in the southeastern part of the city are mostly limestone, while those to the north and west consist mostly of siltstone and shale.

As of the census of 2020, there were 8,108 people living in the city. The average household size during the years 2018–22 was 2.19. The rate of home ownership was 33 percent, and the median value of owner-occupied units was about $133,000. The population density in 2020 was 3,248 people per square mile (8,410 per km²). The reported racial makeup of the city was about 91 percent White and about 4 percent African-American, with other categories totaling about 5 percent. People of Hispanic or Latino origin accounted for about 3 percent of the residents. Between 2018 and 2022, about 3 percent of the city's residents were foreign-born, and about 3 percent of the population over the age of 5 spoke a language other than English at home. In 2020, the city's population included about 5 percent under the age of 18 and about 15 percent who were 65 years of age or older. Females accounted for 52 percent of the total population.

Between 2018 and 2022, of the people who were older than 25, 89 percent had graduated from high school, and 23 percent had at least a bachelor's degree. In 2017, 126 businesses with employees operated in Lock Haven. The mean travel time to work for employees who were at least 16 years old was 21 minutes. The median income for a household in the city during 2018–22 was about $43,000 compared to about $75,000 for the entire United States. The per capita income for the city was about $24,000, and about 25 percent of Lock Haven's residents lived below the poverty line.

Lock Haven's economy, from the city's founding in 1833 until the end of the 19th century, depended heavily on natural resources, particularly timber, and on cheap transportation to eastern markets. Loggers used the Susquehanna River and Bald Eagle Creek to float timber to sawmills in Lock Haven and nearby towns. The West Branch Canal, reaching the city in 1834, connected to large markets downstream, and shorter canals along Bald Eagle Creek added other connections.{{sfn|Miller|1966|pp=44–46}} In 1859, the first railroad arrived in Lock Haven, spurring trade and economic growth.

By 1900, the lumber industry had declined, and the city's economic base rested on other industries, including a furniture factory, a paper mill, a fire brick plant, and a silk mill. In 1938, the Piper Aircraft Corporation, maker of the Piper Cub and other light aircraft, moved its production plant to Lock Haven. It remained one of the city's biggest employers until the 1980s, when, after major flood damage and losses related to Hurricane Agnes in 1972, it moved to Florida. The loss of Piper Aircraft contributed to an unemployment rate of more than 20% in Lock Haven in the early 1980s, though the rate had declined to about 9% by 2000. Another large plant, the paper mill that had operated since the 1880s{{sfn|Wagner|1979|p=134}} in Castanea Township, closed in 2001.{{cite news |agency=Associated Press | title = Plan to Close Paper Mill Staggers Lock Haven | work = Reading Eagle | via = Google News| date =October 18, 2000 |url=https://news.google.com/newspapers?nid=1955&dat=20001019&id=OIs0AAAAIBAJ&pg=5678,1067302 |access-date=September 10, 2019}} By 2005, 32% of the city's labor force was employed in health care, education, or social services, 16% in manufacturing, 14% in retail trade, 13% in arts, entertainment, recreation, accommodation, and food services, and smaller fractions in other sectors. The city's biggest employers, Lock Haven University of Pennsylvania and UPMC Susquehanna Lock Haven hospital, are among the seven biggest employers in Clinton County.

The City of Lock Haven owns the reservoirs and water distribution system for Wayne Township, Castanea Township, and the city. Water is treated at the Central Clinton County Water Filtration Authority Plant in Wayne Township before distribution. The city also provides water to the Suburban Lock Haven Water Authority, which distributes it to surrounding communities. Lock Haven operates a sewage treatment plant for waste water, industrial waste, and trucked sewage from the city and eight upstream municipalities: Bald Eagle Township, Castanea, Flemington, Lamar, Mill Hall, Porter Township, Woodward Township, and Walker Township in Centre County. Storm water runoff from within the city is transported by city-owned storm sewers. Curbside pickup of household garbage is provided by a variety of local haulers licensed by the city; recyclables are picked up once every two weeks. The Clinton County Solid Waste Authority owns and operates the Wayne Township Landfill, which serves Lock Haven.
