Lancaster and York Counties, Pennsylvania<br />

The Modern Era (1900 to Present)<br />

In <strong>the</strong> early twentieth century, creameries were a significant element of Lancaster’s agricultural economy.<br />

In 1916 <strong>the</strong>re were 40 creameries in <strong>the</strong> county. One of <strong>the</strong> biggest, Farmer’s Creamery, was located in<br />

Drumore Township (Roddy 1916). Agricultural land use continued into <strong>the</strong> twentieth century; in 1960,<br />

Lancaster County was <strong>the</strong> largest farming county in Pennsylvania with 4,650 farms (Stevens 1964:345).<br />

In comparison, York County had 2,700 farms, a little more than half of those in Lancaster County<br />

(Stevens 1964:345).<br />

The Columbia & Port Deposit Railroad was <strong>the</strong> principal route <strong>for</strong> moving freight between points on <strong>the</strong><br />

Pennsylvania Main Line and points on <strong>the</strong> Philadelphia, Baltimore, and Washington line. Freight trains<br />

were more efficiently and economically operated through <strong>the</strong> low grade of <strong>the</strong> Lower Susquehanna Valley<br />

ra<strong>the</strong>r than <strong>the</strong> heavier grades used <strong>for</strong> through passenger service (Burgess and Kennedy 1949:375). The<br />

Columbia & Port Deposit Railroad was relocated to higher ground from Conestoga Creek Bridge to Safe<br />

Harbor in 1905–1906 because of construction of <strong>the</strong> Holtwood Dam and <strong>the</strong> resulting lake.<br />

In 1916, <strong>the</strong> Columbia & Port Deposit Railroad and o<strong>the</strong>r lines consolidated into <strong>the</strong> Philadelphia,<br />

Baltimore, & Washington Railroad Company, a subsidiary of <strong>the</strong> Pennsylvania Railroad Company<br />

(Burgess and Kennedy 1949:375–376; 554). The railroad was relocated between Port Deposit and Fite’s<br />

Eddy in 1926–1928, when <strong>the</strong> Conowingo Dam was built. The railroad was electrified in 1938 and <strong>the</strong>n<br />

de-electrified in <strong>the</strong> early 1980s. It is still in active service today and owned by <strong>the</strong> Norfolk/Sou<strong>the</strong>rn<br />

Corporation (Smith 1997; Trower 2002).<br />

Hydroelectric power production facilities were developed beginning in <strong>the</strong> early 1900s to take advantage<br />

of <strong>the</strong> Susquehanna River’s <strong>for</strong>ce. In 1904, <strong>the</strong> York Haven Hydroelectric Station, located at Conewago<br />

Falls, was opened (Sheets 1991:210). The Holtwood Power Plant, which began operation in 1910, was <strong>the</strong><br />

largest producer of electricity at <strong>the</strong> time and is still a major producer of electricity <strong>for</strong> south central<br />

Pennsylvania (Synder and Boyle 1984). By 1916, <strong>the</strong>re were nine hydroelectric plants in Lancaster<br />

County (Roddy 1916). The massive Conowingo Dam was built near Darlington, Maryland a short<br />

distance downstream of <strong>the</strong> Project between 1926 and 1928 to provide hydroelectric power to supply<br />

Philadelphia and sou<strong>the</strong>astern Pennsylvania with electricity. (Lower Susquehanna Heritage Greenway<br />

2006; MHT Determination of Eligibility (DOE) Form, US 1 over Susquehanna River/Conowingo Dam,<br />

HA-1971).<br />

Electricity from <strong>the</strong> Conowingo plant also powered railroad lines between New York and Washington,<br />

D.C., and was used <strong>for</strong> industrial and residential applications. When constructed, Conowingo Dam was<br />

<strong>the</strong> second largest hydroelectric development in <strong>the</strong> United Sates after Niagara Falls (Camden County<br />

Vocationalite, June 1930). It was and still is <strong>the</strong> single largest generation station to be built in one step,<br />

and used <strong>the</strong> most up-to-date technology, as well as <strong>the</strong> largest turbines and generators ever produced<br />

(Maryland Humanities Council 2001:259; Jefferson et al 2007). It is “apparently <strong>the</strong> first dam, of major<br />

size, built entirely by chuting concrete” and reportedly <strong>the</strong> longest slab dam in <strong>the</strong> United States<br />

(Maryland State Highway Administration 1997:463).<br />

Since <strong>the</strong> end of World War II, <strong>the</strong> Lancaster and York County areas have developed several residential<br />

communities. Farmland has declined, population has grown (and continues to grow), and <strong>the</strong> landscape<br />

has became more suburban in nature. A recently renewed interest in <strong>the</strong> region's past has led to physical<br />

and historical revitalization of <strong>the</strong> area. In <strong>the</strong> 1960s, an agreement was passed among Maryland,<br />

Pennsylvania, and New York to begin work on clearing <strong>the</strong> Susquehanna River of sewage, coal-mining<br />

seepage, soil runoff, and chemical fertilizers. At <strong>the</strong> same time, a movement was also taking shape to<br />

clean up <strong>the</strong> Chesapeake Bay.<br />
