Waterfalls, and Wells, 2008 (1:24,000) - Shows gaging stations, gates, lock chambers, reservoirs, springs, seeps, sinks, rises, waterfalls, and wells in Indiana. This layer is derived from the National Hydrography Dataset (NHD). 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 to 1:12,000 scale, adds detail to the original 1:100,000-scale NHD.
