From 2013 to 2015, bathymetric surveys of New York City’s six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs (fig. 1) – Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie – which were constructed from the early 1900s to the 1960s and have an estimated combined storage capacity of more than 460 billion gallons. Problem and Objective The daily and seasonal management of the WOH reservoirs by DEP depends on accurate bathymetric...
