For over two hundred years, the Catskill Mountains have been repeatedly and dramatically transformed by New York City. In Making Mountains, David Stradling shows the transformation of the Catskills landscape as a collaborative process, one in which local and urban hands, capital, and ideas have come together to reshape the mountains and the communities therein. This collaboration has had environmental, economic, and cultural consequences. Early on, the Catskills were an important source of natural resources. Later, when New York City needed to expand its water supply, engineers helped direct the city toward the Catskills, claiming that the mountains offered the purest and most cost-effective waters. By the 1960s, New York had created the great reservoir and aqueduct system in the mountains that now supplies the city with 90 percent of its water. The Catskills also served as a critical space in which the nation's ideas about nature evolved. Stradling describes the great influence writers and artists had upon urban residents - especially the painters of the Hudson River School, whose ideal landscapes created expectations about how rural America should appear. By the mid-1800s, urban residents had turned the Catskills into an important vacation ground, and by the late 1800s, the Catskills had become one of the premiere resort regions in the nation. In the mid-twentieth century, the older Catskill resort region was in steep decline, but the Jewish "Borscht Belt" in the southern Catskills was thriving. The automobile revitalized mountain tourism and residence, and increased the threat of suburbanization of the historic landscape. Throughout each of these significant incarnations, urban and rural residents worked in a rough collaboration, though not without conflict, to reshape the mountains and American ideas about rural landscapes and nature.

New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.
