the Croton water had already dramatically improved both domestic hygiene and interior design. Baths and running water were being built in the private homes of wealthy New Yorkers, and public bathing facilities were constructed for the masses. The water system had another inadvertent consequence. The decline in the number of residents drawing water from the city's wells resulted in a rise in the water table, which flooded many cellars. To address this problem, the city built sewers in many residential streets. By 1852, of sewers had already been constructed. About this time the German cockroach attracted attention and was called the "Croton bug" on the mistaken belief that the aqueduct brought the insects into the homes being connected to the new water supply system. Despite its size, the capacity of the Old Croton Aqueduct could not keep up with the growth of New York City, and construction on a New Croton Aqueduct began in 1885 a few miles east. The new aqueduct, buried much deeper than the old one, went into service in 1890, with three times the capacity of the Old Croton Aqueduct. It currently supplies 10 percent of New York City's water. The Croton Receiving Reservoir continued to supply New York City with drinking water until 1940, when Commissioner of Parks and Recreation Robert Moses ordered it drained and filled to create the Great Lawn and Turtle Pond in Central Park. The old aqueduct remained in service until 1955. In 1987 the northernmost portion was reopened to provide water to Ossining. Old Croton Trail The Old Croton Trail extends for in Westchester County, providing public access along all but four segments — in the Getty Square neighborhood of downtown Yonkers, Tarrytown, Scarborough and Ossining — along the route of the aqueduct. It crosses the lawn of Lyndhurst, following the aqueduct's easement. The trail enters New York City on the eastern side of Van Cortlandt Park and runs through the Bronx alongside Aqueduct Avenue, and the trail continues under the southern part of University Avenue. Both the trail and the tunnel are part of the Old Croton Aqueduct State Historic Park, which was created in 1968 and encompasses the northernmost of the aqueduct and its right-of-way, from Croton Gorge Park to the Yonkers-New York City line. It lies wholly within Westchester County but is under the jurisdiction of the Taconic Region of the New York State Office of Parks,
