Beaver is a borough in and the county seat of Beaver County in the U.S. state of Pennsylvania . It is located at the confluence of the Beaver and Ohio Rivers , approximately 30 miles ( 48 km ) northwest of Pittsburgh . As of the 2010 census , the borough population was 4,531 . The borough is a Tree City USA community . Robert Linn was the mayor of Beaver for 58 years , from 1946 to 2004 , making him one of the longest serving mayors in the United States .
The Cumberland and Pennsylvania Railroad ( C & P ) was an American railroad which operated in Western Maryland . Primarily a coal hauler , it was owned by the Consolidation Coal Company , and was purchased by the Western Maryland Railway ( WM ) in 1944 . The line ran from Cumberland , Maryland to Piedmont , West Virginia , at both points interchanging with the Baltimore and Ohio Railroad . The railroad 's shops were located at Mount Savage , Maryland , also the location of its headquarters . On the way to Piedmont the line passed through ( and under ) Frostburg , Maryland , where the C & P station stands today as the western terminus of the Western Maryland Scenic Railroad .
The Beginning Point of the U.S. Public Land Survey is the point from which the United States in 1786 began the formal survey of the lands known then as the Northwest Territory , now making up all or part of Ohio , Indiana , Illinois , Michigan , and Wisconsin . The survey is claimed to be the first major cadastral survey undertaken by any nation . The point now lies underwater on the state line between Ohio and Pennsylvania . Because it is submerged , a monument commemorating the point is located on the state line between East Liverpool , Ohio and Ohioville , Pennsylvania , adjacent to the nearest roadway . The area around the marker was designated a National Historic Landmark in 1965 .
Ohio /oʊˈhaɪoʊ/ ( listen ) is a state in the East North Central region of the Midwestern United States . Of the fifty states , it is the 34th largest by area , the seventh most populous , and the tenth most densely populated . The state 's capital and largest city is Columbus . Ohio is bordered by Lake Erie to the north , Pennsylvania to the east , West Virginia to the southeast , Kentucky to the southwest , Indiana to the west , and Michigan to the northwest . The state takes its name from the Ohio River , whose name in turn originated from the Seneca word ohiːyo ' , meaning good river , great river or large creek . Partitioned from the Northwest Territory , Ohio was the 17th state admitted to the Union on March 1 , 1803 , and the first under the Northwest Ordinance . Ohio is historically known as the Buckeye State after its Ohio buckeye trees , and Ohioans are also known as Buckeyes . Ohio rose from the wilderness of Ohio Country west of Appalachia in colonial times through the Northwest Indian Wars as part of the Northwest Territory in the early frontier , to become the first non-colonial free state admitted to the union , to an industrial powerhouse in the 20th century before transitioning to a more information and service based economy in the 21st . The government of Ohio is composed of the executive branch , led by the governor ; the legislative branch , which comprises the bicameral Ohio General Assembly ; and the judicial branch , led by the state Supreme Court . Ohio occupies 16 seats in the United States House of Representatives . Ohio is known for its status as both a swing state and a bellwether in national elections . Seven presidents of the United States have been elected who had Ohio as their home state .
Ohioville is a borough in Beaver County , Pennsylvania , United States . The population was 3,533 at the 2010 census .
The Watts Mill Bridge is a pin-connected Pratt pony truss bridge located over the Little Beaver Creek in Cannelton , Pennsylvania , United States . The bridge was constructed in 1878 by the West Penn Bridge Company , based in nearby Beaver Falls PA . The bridge is located in a valley approximately a quarter mile north of the North Country Trail . The bridge was listed on the National Register of Historic Places in 1988 . When the bridge was given this designation by the NRHP , it was simply known as the Bridge in South Beaver Township . It is the only bridge in Beaver County on the National Register for itself , although the Bridgewater-Rochester Bridge over the Beaver River is part of the Bridgewater Historic District in Bridgewater to the south . In 2004 , the bridge , which was becoming rusty and falling into disrepair and considered for demolition by PennDOT , was placed on the Top Ten Best Historic Preservation Opportunities in the Pittsburgh Area by the Young Preservationists Association of Pittsburgh . No major renovations have been done to the bridge .
Little Beaver Creek is a wild and scenic area in Ohio . The Little Beaver Creek watershed is located primarily in Columbiana County in eastern Ohio , and in portions of Carroll County , Mahoning County , and western Pennsylvania , draining approximately 605 mi² ( 1,567 km² ) , of which 503 mi² ( 1,303 km² ) are in Ohio . The watershed in total size covers an area of approximately 510 square miles , with about 80% of this being situated in Ohio . The great majority of land within the watershed is privately owned . Within the watershed are roughly 808 miles of linear streams . The creek is protected by a number of classifications , including Ohio Wild and Scenic River and National Scenic River , as well as being part of Ohio 's state park system . It is the only major river in Ohio to have dual State Wild and Scenic and National Scenic River designations , and was the first in the country to earn both distinctions . The creek empties into the Ohio River just east of East Liverpool , Ohio . The now-defunct Sandy and Beaver Canal was constructed alongside the creek . According to an Ohio Department of Natural Resources study conducted in 2004 , Little Beaver Creek is an exceptionally clean waterway with a highly diverse ecosystem . It supports 63 species of fish , 49 mammal species , 270 species of migratory and resident birds and 46 species of reptiles and amphibians , including the rare and protected salamander known as the hellbender . It is thought to be the only riparian corridor in the United States which shows geologic evidence of all five ice ages .
Darlington Township is a township in Beaver County , Pennsylvania , United States . The population was 1,962 at the 2010 census .
South Beaver Township is a township in Beaver County , Pennsylvania , United States . The population was 2,717 at the 2010 census .
The Bridgewater Historic District is a historic district in Bridgewater , Pennsylvania , United States . Listed on the National Register of Historic Places on June 28 , 1996 , it includes buildings built between 1818 and 1933 , although the most significant buildings in the district are those that were built before the Civil War in the 1860s . Located at the confluence of the Ohio and Beaver Rivers , Bridgewater was a transportation center as the terminus of the Bridgewater Canal during the pre-Civil War era . This prosperity is reflected in many of the district 's buildings : the adjacent communities of Beaver and Rochester were less significant during that time , and accordingly have a much smaller number of period buildings . The district includes the Bridgewater-Rochester Bridge , a canal lock for the Bridgewater Canal , and 97 buildings . Among its contributing properties are three churches , the Keystone Bakery , and the William B. Dunlap Mansion , which is separately listed on the Register . Because the bridge spans the Beaver River to Rochester , a small portion of the district is located in Rochester . Another building in the district is the house of Joseph Hemphill , a local landowner who platted much of Bridgewater in 1818 . Built in 1818 , it is Bridgewater 's oldest extant house . During Bridgewater 's heyday , Bridge Street was a vibrant downtown street . Its buildings housed a wide variety of businesses , ranging from offices to stores to metalworking shops . Among the leading businesses of Bridge Street , the Keystone Bakery , was once the largest bakery in Western Pennsylvania outside of Pittsburgh and Allegheny .
The Beaver River is a tributary of the Ohio River in Western Pennsylvania in the United States with a length of approximately 21 mi ( 34 km ) . It flows through a historically important coal-producing region north of Pittsburgh . The Beaver River is formed in Lawrence County by the confluence of the Mahoning and Shenango rivers in the Mahoningtown neighborhood of New Castle . It flows generally south , past West Pittsburg and Homewood . It receives Connoquenessing Creek west of Ellwood City and flows past Beaver Falls and New Brighton . It joins the Ohio at Bridgewater and Rochester ( flowing between these two towns ) at the downstream end of a sharp bend in the Ohio approximately 20 mi ( 32 km ) northwest of ( and downstream from ) Pittsburgh . In the lower reaches near the Ohio River , the Beaver cuts through a gorge of underlying sandstone . The river is roughly parallel to the border with the state of Ohio , with both Interstate 376 and Pennsylvania Route 18 running parallel to the river itself . The river , which flows throughout the northern half of Beaver County , serves as the namesake of the county as well as several locales in both Beaver and Lawrence County . The river itself was either named for King Beaver ( Tamaqua ) of the Delaware nation that had migrated to the area in the late 1740s , or for the animal itself . Until the partition of Lawrence County from parts of Beaver and Mercer County in 1849 , the river was entirely located in Beaver County , with its upstream terminus being at the border between Beaver and Mercer County from 1800-1849 .
Bridgewater is a borough in Beaver County , Pennsylvania , United States . The population was 704 at the 2010 census . It is best known as the home of the Bruster 's Ice Cream chain . A few scenes in the 1986 movie Gung Ho were also shot in Bridgewater . Much of Bridgewater , including its two major streets are included in the Bridgewater Historic District .
Rochester is a borough in Beaver County , Pennsylvania , United States . Located 25 miles ( 40 km ) northwest of Pittsburgh , it is part of the Pittsburgh metropolitan area . The population was 3,657 at the 2010 census . Like many places around Pittsburgh , Rochester was a former industrial hub , home to the H. C. Fry Glass Company , and was a major junction on the Pennsylvania Railroad . Recently , Rochester has been a background for films , including the 1986 movie Gung Ho , the 1996 movie Kingpin , and the 2000 movie Wonder Boys .
The Carnegie Free Library of Beaver Falls is a historic Carnegie library in the city of Beaver Falls , Pennsylvania , United States . Erected as Beaver County 's first library building , it was financed by Andrew Carnegie and designed by a leading Pittsburgh architect in grand architectural style that helped to redefine the image of the typical Carnegie library . Numerous community organizations have used its space , which remains in continued use as a library , and it has been named a historic site .
Beaver Falls is a city in Beaver County , Pennsylvania , United States . The population was 8,987 at the 2010 census . It is located 31 miles ( 50 km ) northwest of Pittsburgh , and on the Beaver River , six miles ( 9 km ) north of its confluence with the Ohio River .
A Carnegie library is a library built with money donated by Scottish-American businessman and philanthropist Andrew Carnegie . A total of 2,509 Carnegie libraries were built between 1883 and 1929 , including some belonging to public and university library systems . 1,689 were built in the United States , 660 in the United Kingdom and Ireland , 125 in Canada , and others in Australia , South Africa , New Zealand , Serbia , Belgium , France , the Caribbean , Mauritius , Malaysia , and Fiji . At first , Carnegie libraries were almost exclusively in places where he had a personal connection - namely his birthplace in Scotland and the Pittsburgh , Pennsylvania area , his adopted home-town . Yet , beginning in the middle of 1899 , Carnegie substantially increased funding to libraries outside these areas . In later years few towns that requested a grant and agreed to his terms were refused . By the time the last grant was made in 1919 , there were 3,500 libraries in the United States , nearly half of them built with construction grants paid by Carnegie .
The James Beach Clow House is a historic house in northern Beaver County , Pennsylvania , United States . Located in North Sewickley Township near the community of Ellwood City , :1 the house is a rare surviving example of 19th-century Greek Revival farmhouses in Beaver County . The Clow House was built circa 1830 by War of 1812 veteran James Beach Clow , a native of Pitt Township in Allegheny County , upon land that he bought in 1821 . A leading man in his community , Clow served as justice of the peace in eastern Beaver County in 1830 . Besides his position as a gentleman farmer , Clow was an industrialist , holding a share in a sawmill near his farm . He sold the property to his son Samuel in 1844 , but continued to live in the house until his death ten years later . :7 Although the house remained Samuel 's home until his death in 1893 , it was also a dormitory for students attending a school across the road during most of the 1870s . After the deaths of Samuel and his widow , the property passed through several different owners before farming ended in 1950 . Besides the house , early buildings on the property include an original outhouse and a spring house . The property also included an early barn and miscellaneous multi-purpose building , but these two structures were removed in 1959.:2 Today , the house lies along Chapel Drive southeast of Ellwood City ; its prominent hilltop location makes it visible to the south and east to a distance of several miles . Although a modern residential subdivision is located along Chapel immediately to the north of the Clow property , it retains much of its historic integrity amid a primarily rural setting . :2 , 3 , 14 This places it in contrast with most period wooden Greek Revival farmhouses in rural Beaver and Lawrence counties : nearly all surviving examples of this type of architecture have been heavily modified .
North Sewickley Township is a township in Beaver County , Pennsylvania , United States . The population was 5,488 at the 2010 census .
The William B. Dunlap Mansion was a historic house in Bridgewater , Pennsylvania , United States . Erected in 1840 on a bluff over the Beaver River in the northern part of the borough , it has been ranked as the grandest and best-preserved 19th-century house in Bridgewater . :2 , 4 As of January 17 , 2017 , the structure was demolished by borough authorities following condemnation . The mansion was built for coffee entrepreneur James Arbuckle , whose architect employed the Greek Revival style of architecture . Arbuckle lived in the house until 1865 , when he sold it to Samuel R. Dunlap and his family . Among the mansion 's new residents was Samuel 's son William , who ran his river transportation business from the house . Upon Samuel 's death in 1890 , the house passed into William ; he continued to reside at the property until his own death in 1922 . During these years , the house was the home of a public official : William was elected to represent the 46th District in the Pennsylvania State Senate in 1890 , and he remained in this position until his death . :4 After his death , the house passed through the hands of few owners ; it changed ownership very few times and was only rarely vacant , and thus it has seen less change than most period houses . :3 Except for a period as the home of a veterans ' organization , the mansion has always been used as a residence , although would-be buyers sought to convert it into offices or a print shop . :5 Dunlap 's mansion is a three-story brick structure built on a stone foundation , with four large chimneys and a cedar interior . :3 Although the house is currently surrounded by a lawn and shrubs , it was once surrounded by a formal garden that may have been larger than any other such garden in western Pennsylvania .
William Boyd Dunlap was a former Democratic member of the Pennsylvania State Senate . He worked as a riverboat captain . He was a delegate to the 1876 Democratic National Convention . He represented the 46th senatorial district in the Pennsylvania State Senate from 1891 to 1894 . William B. Dunlap Mansion , his home in Bridgewater , Pennsylvania , is on the National Register of Historic Places .
Old Economy Village is a historic settlement in Ambridge , Beaver County , Pennsylvania , United States . Administered by the Pennsylvania Historical and Museum Commission , it lies on the banks of the Ohio River and is surrounded by downtown Ambridge . The Village is the last of three settlements established by the Harmony Society in the United States ( another in Pennsylvania and one in Indiana ) . Established in 1824 , it was designated a National Historic Landmark District in 1966 under the name of Old Economy .
Pennsylvania Route 65 ( PA 65 , also known as the 65th Infantry Division Memorial Highway ) , is a major 51-mile-long ( 82 km ) state highway located in western Pennsylvania , United States . The route , traveling north-south from the Interstate 279/U.S . Route 19 Truck ( I-279/US 19 Truck ) concurrency in Pittsburgh north to the PA 108/PA 168 concurrency in New Castle , connects downtown Pittsburgh to the northwestern portion of the Pittsburgh Metropolitan Area . PA 65 is similar in its purpose to PA 18 and PA 51 , both of which run parallel to PA 65 at one point or another ; however , the three routes pass through different cities for most of their respective alignments . The route begins in the Golden Triangle of Pittsburgh as a limited-access highway , following the bank of the Allegheny and Ohio rivers around the Manchester neighborhood , passing north of Heinz Field and west of PNC Park . While limited-access , the road becomes Ohio River Boulevard , named for the river that PA 65 parallels for 25 miles ( 40 km ) between the city of Pittsburgh and the borough of Rochester . Outside of the city , the road becomes a four-lane at-grade roadway to Rochester , with some portions featuring a divided highway . North of Rochester , PA 65 narrows to two lanes and passes through predominantly rural land , running concurrent with PA 18 and PA 288 as it heads north . In Pittsburgh , the boulevard was one of the deadliest roads in the city from the 1970s to the early 1980s .
Ambridge is a borough in Beaver County , Pennsylvania , United States . Incorporated in 1905 as a company town by the American Bridge Company , Ambridge is located 16 miles ( 25 km ) northwest of Pittsburgh , along the Ohio River . The population was 7,050 at the 2010 census .
The Harmony Society was a Christian theosophy and pietist society founded in Iptingen , Germany , in 1785 . Due to religious persecution by the Lutheran Church and the government in Württemberg , the group moved to the United States , where representatives initially purchased land in Butler County , Pennsylvania . On February 15 , 1805 , the group of approximately 400 followers formally organized the Harmony Society , placing all their goods in common . Under its founder and spiritual leader , Johann Georg Rapp ( 1757-1847 ) ; Frederick ( Reichert ) Rapp ( 1775-1834 ) , his adopted son who managed its business affairs ; and their associates , the Society existed for one hundred years , roughly from 1805 until 1905 . Members were known as Harmonists , Harmonites , or Rappites . The Society is best known for its worldly successes , most notably the establishment of three model communities , the first at Harmony , Pennsylvania ; the second , also called Harmony , in the Indiana Territory , now New Harmony , Indiana ; and the third and final town at Economy , now Ambridge , Pennsylvania .
Fort McIntosh was an early American log frontier fort situated near the confluence of the Ohio River and the Beaver River in what is now Beaver , Pennsylvania . The fortress was constructed in 1778 under the direction of Lt. Col. Cambray-Digny , a French engineer , and named in honor of General Lachlan McIntosh . The fortress was the site of the signing of the Treaty of Fort McIntosh on January 21 , 1785 . It was occupied until it was abandoned in 1791 . After the Revolution , the fort was the home of the First American Regiment , the oldest active unit in the United States Army . The fort was in the form of a trapezoid , about 150 feet on each side , with raised earthen bastions on each corner . Log palisades connected the bastions , and a 15 foot wide ditch protected three sides of the fort , with the 130 foot slope to the Ohio River protecting the other side . Inside were three barracks , warehouses , officer 's quarters , a forge , kitchen , and powder magazines . The fort may have had either two or four iron cannon . Around the year 1976 , citizens of the nearby community of Beaver decided , with great fanfare , to excavate the pilings and remaining stone foundations of the original Ft. McIntosh .

The Ohio River is a 981-mile ( 1,579 km ) long river in the United States . It is located in the midwestern United States , flowing southwesterly from western Pennsylvania south of Lake Erie to its mouth on the Mississippi River at the southern tip of Illinois . It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States . The river flows through or along the border of six states , and its drainage basin includes parts of 15 states . Through its largest tributary , the Tennessee River , the basin includes several states of the southeastern U.S . It is the source of drinking water for three million people . The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the water level falls 26 ft. in 2 miles and is impassible for navigation . The McAlpine Locks and Dam , a shipping canal bypassing the rapids , now allows commercial navigation from the Forks of the Ohio at Pittsburgh to the Port of New Orleans at the mouth of the Mississippi on the Gulf of Mexico . The name Ohio comes from the Seneca , Ohi : yo ' , lit . Good River .

A lock is a device used for raising and lowering boats , ships and other watercraft between stretches of water of different levels on river and canal waterways . The distinguishing feature of a lock is a fixed chamber in which the water level can be varied ; whereas in a caisson lock , a boat lift , or on a canal inclined plane , it is the chamber itself ( usually then called a caisson ) that rises and falls . Locks are used to make a river more easily navigable , or to allow a canal to cross land that is not level . Later canals used more and larger locks to allow a more direct route to be taken . Since 2016 , the largest lock worldwide is the Kieldrecht Lock in the Port of Antwerp , Belgium .
A dam is a barrier that stops or restricts the flow of water or underground streams . Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation , human consumption , industrial use , aquaculture , and navigability . Hydropower is often used in conjunction with dams to generate electricity . A dam can also be used to collect water or for storage of water which can be evenly distributed between locations . Dams generally serve the primary purpose of retaining water , while other structures such as floodgates or levees ( also known as dikes ) are used to manage or prevent water flow into specific land regions . The earliest known dam is the Jawa Dam in Jordan , dating to 3,000 BC . The word dam can be traced back to Middle English , and before that , from Middle Dutch , as seen in the names of many old cities . The first known appearance of dam occurs in 1165 . However , there is one village , Obdam , that is already mentioned in 1120 . The word seems to be related to the Greek word taphos , meaning grave or grave hill . [ citation needed ] So the word should be understood as dike from dug out earth . The names of more than 40 places ( with minor changes ) from the Middle Dutch era ( 1150-1500 CE ) such as Amsterdam ( founded as 'Amstelredam ' in the late 12th century ) and Rotterdam , also bear testimony to the use of the word in Middle Dutch at that time .

The United States Senate is the upper chamber of the United States Congress , which , along with the United States House of Representatives - the lower chamber - constitutes the legislature of the United States . The Senate chamber is located in the north wing of the Capitol Building , in Washington , D.C . The composition and powers of the Senate are established by Article One of the United States Constitution . The Senate is composed of senators , each of whom represents a single state in its entirety . Each state , regardless of its population size , is equally represented by two senators who serve staggered terms of six years . There being at present 50 states in the Union , there are currently 100 senators . From 1789 to 1913 , senators were appointed by legislatures of the states they represented ; they are now elected by popular vote , following the ratification of the Seventeenth Amendment in 1913 . As the upper chamber of Congress , the Senate has several powers of advice and consent which are unique to it . These include the approval of treaties , and the confirmation of Cabinet secretaries , Supreme Court justices , federal judges , flag officers , regulatory officials , ambassadors , other federal executive officials and other federal uniformed officers . In addition to these , in cases wherein no candidate receives a majority of electors for vice president , the duty falls to the Senate to elect one of the top two recipients of electors for that office . Furthermore , the Senate has the responsibility of conducting the trials of those impeached by the House . The Senate is widely considered both a more deliberative and more prestigious body than the House of Representatives due to its longer terms , smaller size , and statewide constituencies , which historically led to a more collegial and less partisan atmosphere .

The Recreational Demonstration Area program ( also known as the Recreation Demonstration Area program ) was a National Park Service program during the 1930s and early 1940s that built forty-six public parks in twenty-four states on 397,000 acres ( 1,606.6 km2 ) , chiefly near urban areas in the United States . The NPS used labor from a variety of Great Depression federal relief programs , chiefly the Civilian Conservation Corps and Works Progress Administration , to build recreational demonstration areas . By the end of World War II , the recreational demonstration areas had all either become National Park Service units or been given to their states for use as state parks . The goals of the Recreation Demonstration Area program were typically threefold : 1 ) to develop land as a park ; 2 ) to provide employment ; and 3 ) to create new parks near urban areas . For the first goal , in some cases the land developed was purchased from sub-optimal farmers , providing some of the poorest farmers with relief . In other cases , state lands ( in state forests or parks ) were developed . In the second case , the CCC and WPA laborers received payment , and in the CCC , room and board . Finally , the residents of nearby urban areas benefited from new nearby recreation areas .
The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s , beginning in the United States . The timing of the Great Depression varied across nations ; in most countries , it started in 1929 and lasted until the late 1930s . It was the longest , deepest , and most widespread depression of the 20th century . The Great Depression is commonly used as an example of how intensely the world 's economy can decline . The Great Depression started in the United States after a major fall in stock prices that began around September 4 , 1929 , and became worldwide news with the stock market crash of October 29 , 1929 , ( known as Black Tuesday ) . Between 1929 and 1932 , worldwide gross domestic product ( GDP ) fell by an estimated 15% . By comparison , worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession . Some economies started to recover by the mid-1930s . However , in many countries , the negative effects of the Great Depression lasted until the beginning of World War II . The Great Depression had devastating effects in countries both rich and poor . Personal income , tax revenue , profits and prices dropped , while international trade plunged by more than 50% . Unemployment in the U.S. rose to 25% and in some countries rose as high as 33% .
