About Long Valley

Long Valley is an unincorporated community and census-designated place (CDP) located within Washington Township, in Morris County, in the U.S. state of New Jersey. Once known as German Valley from its foundation during the colonial era, the community was renamed in response to anti-German sentiment during World War I. As of the 2010 United States Census, the CDP's population was 1,879. == History == In 1705, a number of German Reformed, residing between Wolfenbüttel and Halberstadt, fled to Neuwied, a town of Rhenish Prussia, where they remained for two years before proceeding on to Holland. In 1707, they embarked for the British colony of New York. Before arriving, their ship was blown off-course to the south, where they were carried into the Delaware Bay and landed in Philadelphia. From there, they embarked by land eastward to what became known as the "German Valley" in what was then called "Nova Caesaria" (New Jersey), located in today's Morris County, New Jersey. == Geography == According to the United States Census Bureau, the CDP had a total area of 4.623 square miles (11.974 km2), including 4.566 square miles (11.825 km2) of land and 0.057 square miles (0.148 km2) of water (1.24%).There are several bodies of water, including several man-made lakes used for agriculture and a portion of the Raritan River that are not reflected in the calculation of water area.
