The city of Lock Haven is the county seat of Clinton County , in the U.S. state of Pennsylvania . Located near the confluence of the West Branch Susquehanna River and Bald Eagle Creek , it is the principal city of the Lock Haven Micropolitan Statistical Area , itself part of the Williamsport – Lock Haven combined statistical area . At the 2010 census , Lock Haven 's population was 9 @,@ 772 .
Built on a site long favored by pre @-@ Columbian peoples , Lock Haven began in 1833 as a timber town and a haven for loggers , boatmen , and other travelers on the river or the West Branch Canal . Resource extraction and efficient transportation financed much of the city 's growth through the end of the 19th century . In the 20th century , a light @-@ aircraft factory , a college , and a paper mill , along with many smaller enterprises , drove the economy . Frequent floods , especially in 1972 , damaged local industry and led to a high rate of unemployment in the 1980s .
The city has three sites on the National Register of Historic Places — Memorial Park Site , a significant pre @-@ Columbian archaeological find ; Heisey House , a Victorian @-@ era museum ; and Water Street District , an area with a mix of 19th- and 20th @-@ century architecture . A levee , completed in 1995 , protects the city from further flooding . While industry remains important to the city , about a third of Lock Haven 's workforce is employed in education , health care , or social services .

The earliest settlers in Pennsylvania arrived from Asia between 12000 BCE and 8000 BCE , when the glaciers of the Pleistocene Ice Age were receding . <unk> point spearheads from this era , known as the Paleo @-@ Indian Period , have been found in most parts of the state . Archeological discoveries at the Memorial Park Site <unk> 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 . 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 . First contact with Europeans occurred in Pennsylvania between 1500 and 1600 CE .

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 325 @-@ acre ( 1 @.@ 32 km2 ) 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 . 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 .
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 , white 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 white 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 . It was the westernmost of 11 mostly primitive forts along the West Branch ; Fort Augusta , 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 white 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 50 miles ( 80 km ) from Fort Reed ; some did not return for five years . 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 .

Lock Haven was laid out as a town in 1833 , and it became the county seat in 1839 , when the county was created out of parts of Lycoming and Centre counties . Incorporated as a borough in 1840 and as a city in 1870 , 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 .
The West Branch Canal , which opened in 1834 , ran 73 miles ( 117 km ) from Northumberland to <unk> , about 5 miles ( 8 km ) 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 , 24 miles ( 39 km ) 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 12 feet ( 4 m ) wide and 80 feet ( 24 m ) 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 ) followed the opening of the canal .
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 150 feet ( 46 m ) from one another , stretched in a line from the dam to a point 3 miles ( 5 km ) 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 .
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 <unk> ' 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 , 56 miles ( 90 km ) to the southwest . The two rail lines soon became part of the network controlled by the Pennsylvania Railroad .
During the era of log floating , <unk> 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 28 feet ( 9 m ) wide — narrow enough to pass through the chutes — and 150 feet ( 46 m ) to 200 feet ( 61 m ) long . 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 16 feet ( 5 m ) high . The jam eventually trapped another 200 log rafts , and 2 canal boats , The Mammoth of Newport and The Sarah Dunbar .
In terms of board feet , the peak of the lumber era in Pennsylvania arrived in about 1885 , when 1 @.@ 9 million logs went through the boom at Williamsport . These logs produced a total of about 226 million board feet ( 533 @,@ 000 m3 ) 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 .
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 . 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 3 miles ( 5 km ) 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 , 3 miles ( 5 km ) miles south of Mill Hall , and to Avis 10 miles ( 16 km ) 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 .
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 . 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 , 48 miles ( 77 km ) west of Lock Haven , in 1989 .
An 8 @-@ acre ( 3 @.@ 2 ha ) 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 .

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 120 miles ( 193 km ) miles downstream from Lock Haven , occurred in 1784 , 1865 , 1889 , 1894 , 1902 , 1936 , and 1972 . Readings from the Williamsport stream gauge , 24 miles ( 39 km ) miles 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 . 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 . The biggest flood occurred on March 18 , 1936 , when the river crested at 32 @.@ 3 feet ( 9 @.@ 8 m ) , which was about 11 feet ( 3 @.@ 4 m ) above the flood stage of 21 feet ( 6 @.@ 4 m ) .
The third biggest flood , cresting at 29 @.@ 8 feet ( 9 @.@ 1 m ) in Lock Haven , occurred on June 1 , 1889 , and coincided with the Johnstown Flood . The flood demolished Lock Haven 's log boom , and millions of feet of stored timber were swept away . The flood damaged the canals , which were subsequently abandoned , and destroyed the last of the canal boats based in the city .
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 6 to 12 inches ( 152 to 305 mm ) with local amounts up to 19 inches ( 483 mm ) in western Schuylkill County , about 75 miles ( 121 km ) southeast of Lock Haven . At Lock Haven , the river crested on June 23 at 31 @.@ 3 feet ( 9 @.@ 5 m ) , second only to the 1936 crest . The flood greatly damaged the paper mill and Piper Aircraft .
Federal , state , and local governments began construction in 1992 of barriers to protect the city . The project included a levee of 36 @,@ 000 feet ( 10 @,@ 973 m ) and a flood wall of 1 @,@ 000 feet ( 305 m ) along the Susquehanna River and Bald Eagle Creek , closure structures , retention basins , a pumping station , and some relocation of roads and buildings . Completed in 1995 , the levee protected the city from high water in the year of the Blizzard of 1996 , and again 2004 , when rainfall from the remnants of Hurricane Ivan threatened the city .

U.S. Route 220 , a major transportation corridor , skirts the city on its south edge , intersecting with Pennsylvania Route 120 , which passes through the city and connects it with <unk> in northern Clinton County . Other highways entering Lock Haven include Pennsylvania Route 664 and Pennsylvania Route 150 , which connects to Avis .
The city and nearby smaller communities — 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 . 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 . Large parts of the city are flat , but slopes rise to the west , and very steep slopes are found along the river , on the university campus , and along Pennsylvania Route 120 as it approaches U.S. Route 220 .

= = Economy = =
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 . 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 in Castanea Township , closed in 2001 . 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 Lock Haven Hospital , are among the seven biggest employers in Clinton County .
