Hydrography High Resolution, 1:24,000, Northeast Hydrography represents stream centerlines and off centerlines with greater than 30 hectare flow accumulation for the Northeast region. This dataset was developed as part of the Designing Sustainable Landscapes project led by Professor Kevin McGarigal of the University of Massachusetts and sponsored by the North Atlantic Landscape Conservation Cooperative; for more information about the entire project see: http://www.umass.edu/landeco/research/dsl/dsl.html The purpose of this dataset is to improve the National Hydrography Dataset (NHD) for the Northeast region. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat...

The study area includes 12-13 sampling sites that follow a transect spanning the entire length of the reservoir from the Colorado River inflow to the Glen Canyon dam, as well as the San Juan River arm, the Escalante River arm and West Canyon. Bed sediment samples were analyzed for mercury speciation, methylmercury production and degradation rates, total reduced sulfur, iron speciation, organic content, and 16S rRNA gene templates as a proxy for microbial abundances....

NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

The Data Distribution Site directs you to the LANDFIRE Viewer, where you can view the 30-meter resolution layers, metadata, and descriptions. This viewer provides assorted tools allowing the ability to interact and manipulate any data displayed within the viewer. Data extents are defined by dragging an extent or defining coordinates. All LANDFIRE data are free and available to everyone. The default download is an ESRI grid raster format with attributes and includes metadata in a zipped file. Options to specify different data formats and projections are available through the viewer's Modify Data Request...
