Question: What is the population of one of the towns that Watervliet previously encompassed?
Context: Beaverdam Lake-Salisbury Mills was a census-designated place (CDP) in Orange County, New York, United States.  It encompassed a region in the corner of the towns of Blooming Grove, Cornwall, and New Windsor.  As of the 2000 census, its population was 2,779.  For the 2010 census, the area was counted as two separate CDPs: Beaver Dam Lake (pop.  2,242) in the towns of Blooming Grove and New Windsor and Salisbury Mills (pop.  536) in the towns of Blooming Grove and Cornwall.  Beaverdam Lake is also the name of a lake next to the community. Cyropolis was the largest of seven towns in the region that Alexander the Great targeted for conquest in 329 BC.  His goal was the conquest of Sogdiana.  Alexander first sent Craterus to Cyropolis, the largest of the towns holding Sogdiana against Alexander's forces.  Craterus' instructions were to ""take up a position close to the town, surround it with a ditch and stockade, and then assemble such siege engines as might suit his purpose..."" The idea was to keep the inhabitants focused on their own defenses and to prevent them from sending assistance out to the other towns.  Starting from Gazza, Alexander went on to conquer the other surrounding towns.  Five of the seven towns were taken in two days.  Many of the inhabitants were killed.  Alexander then arrived at Cyropolis, which was the best fortified of the towns and had the largest population.  It also had reputedly the best fighters of the region.  Alexander battered Cyropolis' defenses with the siege engines.  While the bombardment went on, Alexander ordered certain of his troops to sneak through a dried-up water course that went under the town's wall.  Alexander also joined on this mission and once inside his troops opened the town's gate to admit his attacking force.  Once the natives saw that the town was taken, they fell violently upon the attackers.  Alexander received a violent blow from a stone that landed upon his head and neck.  Craterus was wounded by an arrow, but the defenders were driven off.  Arrian puts the defender's force at about 15,000 fighting men and claims that 8,000 of them were killed in the first phase of the operation.  The rest apparently sought refuge inside the town's central fortress, but surrendered after one day for lack of water. The town of Watervliet ( or ) was a town that at its height encompassed most of present-day Albany County and most of the current town of Niskayuna in neighboring Schenectady County, in the state of New York, United States.  Just prior to its dissolution, the town encompassed the current towns of Colonie and Green Island and the city of Watervliet. Green Island is a coterminous town and village in Albany County, New York, United States some 8 miles (13 km.)  north of Albany, New York.  Green Island is one of only five such town-village amalgams in New York.  The population was 2,620 at the 2010 census.  The postal code is 12183.

Norfolk County, Massachusetts Colony was one of the original four counties created in the Massachusetts Bay Colony.  The land was originally granted as separate from Massachusetts, but boundary disputes among the settlers led to their petitioning to join the colonial government to the south.  The county was created by the Massachusetts General Court on May 10, 1643, when it was ordered "that the whole plantation within this jurisdiction be divided into four sheires".  Norfolk County contained the settlements of Salisbury, Hampton, Haverhill, Exeter, Dover, and Portsmouth.  It effectively encompassed all settlements from the Merrimack River, north to the Piscataqua River, and extending inland about a dozen miles.  In 1680, the Province of New Hampshire was formally separated from Massachusetts, with Norfolk County forming the core.  Massachusetts retained the northern bank of Merrimack River and the towns of Salisbury and Haverhill were added to Essex County.  Hampton, Exeter, Dover, and Portsmouth were governed at two levels, town and province/colony, until 1769, when New Hampshire was itself divided into counties, so that Norfolk ceased to exist. The New Town (Czech: Nové Město ) is a quarter in the city of Prague in the Czech Republic.  New Town is the youngest and largest of the five independent (from the Middle Ages until 1784) towns that today comprise the historic center of modern Prague.  New Town was founded in 1348 by Charles IV just outside the city walls to the east and south of the Old Town and encompassed an area of 7.5 km²; about three times the size of the Old Town.  The population of Prague in 1378 was well over 40,000, perhaps as much as twice that, making it the 4th most populated city north of the Alps and, by area, the 3rd largest city in Europe.  Although New Town can trace its current layout to its construction in the 14th century, only few churches and administrative buildings from this time survive.  There are many secular and educational buildings in New Town, but also especially magnificent gothic and baroque churches.  These nevertheless are not the main drawing points for tourists.  New Town's most famous landmark is Wenceslas Square, which was originally built as a horsemarket and now functions as a center of commerce and tourism.  In the 15th century, the Novoměstská radnice, or New Town Hall, was the site of the first of the three defenestrations of Prague. Sint-Laureins (] ; Dutch for Saint Lawrence) is a municipality located in the Flemish province of East Flanders, in Belgium.  The municipality comprises the towns of Sint-Jan-in-Eremo, Sint-Laureins proper, Sint-Margriete, Waterland-Oudeman and Watervliet.  On January 1, 2011, Sint-Laureins had a total population of 6,535.  The total area is 74.50 km² which gives a population density of 88 inhabitants per km². The Division of Wimmera was an Australian Electoral Division in the state of Victoria.  It was named after the Wimmera region in which it was located.  It originally encompassed the towns of Mildura, Swan Hill and Warracknabeal, but by the time it was abolished in 1977, it had drifted south and grown smaller to only include Ararat, Horsham and Maryborough.  The Division was proclaimed in 1900, and was one of the original 75 divisions to be contested at the first Federal election.  It was abolished at the redistribution of 31 October 1977. A town or eup is an administrative unit in South Korea; along with township (rural), a town (urban) is one of the divisions of a county, and of some cities with a population of less than 500,000.  The main town or towns in a county—or the secondary town or towns within a city's territory—are designated as towns.  Towns are subdivided into villages.  In order to form an town, the minimum population required is 20,000.
