These data depict the hydrography (water) resources of Rocky Mountain National Park. It is derived and developed from a number of sources. These include:

> 1:24000-scale USGS Digital Line Graph (DLG) data.> 1:24000-scale USFS Cartographic Feature File (CFF) data, > GPS (Global Positioning System) data. These data have also been updated and upgraded using heads-up digitizing using USGS DOQ's and color DOQ's developed for Rocky Mountain National Park as a backdrop. **NOTE** - These data are available as either an ESRI coverage, or as separate ESRI shapefiles, and this one metadata file is valid for all those data. When in COVERAGE format, both arc and polygon data are in the one dataset. Due to the limitations of the ESRI shapefile format, this hydrography data is contained in two separate shapefiles: Lakes.shp (polygons) and Streams.shp (vectors). These data were originally compiled in 1995, and have been incrementally updated and upgraded as needed. These data depict only vector and/or polygon features (streams, lakes, etc.). Point hydrography features (wells, springs, diversions, etc.) are located in other datasets of the Rocky Mountain National Park GIS database.

These data cover a 39 quad area centered on Rocky Mountain National Park. The 7.5 minute USGS quads covered are: Clark Peak, Chambers Lake, Comanche Peak, Pingree Park, Crystal Mountain, Mount Richthofen, Fall River Pass, Trail Ridge, Estes Park, Glen Haven, Bowen Mountain, Grand Lake, McHenrys Peak, Longs Peak, Panorama Peak, Trail Mountain, Shadow Mountain, Isolation Peak, Allens Park, Raymond, Granby, Strawberry Lake, Monarch Lake, Ward, Gold Hill, Rawah Lakes, Boston Peak, Kinikinik, Rustic, Big Narrows, Poudre Park, Buckhorn Mountain, Drake, Pinewood Lake, Lyons, Boulder, Laporte, Horsetooth Reservoir, and Masonville.

This is a vector line dataset representing the lake and stream features in Rocky Mountain National Park. This dataset is utilizing the updated Core Data Standard dated 08/10/2016.
