Abstract:
Colorado hydrographic dataset sourced primarily from 1:100K USGS DLGs. This dataset has been modified for pulic distribution. |
Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
Colorado hydrographic dataset sourced primarily from 1:100K USGS DLGs. This dataset has been modified for pulic distribution.
This dataset is intended to graphically represent Colorado's hydrography at a scale no less than 1:24,000.
1:24000 scale, statewide, stream network features. Data Sources: 1:24K USGS DRGs. NOTE: You may notice gaps between stream network segments. These are most likely due to the intersection with a ditch. A resource to check this is the 1:24,000 scale DRG. Feature Items- Arcs: FEATURE, DOW_NAME, DOW_NAME2, NAME1, NAME2, STRAHLER, HYDROCODE, QUADCODE, SOURCE, AREA_BIO, BRAID. FEATURE. This attribute was created to simplify feature type. It was created by combining several fields which have been omitted in this version of the dataset. This may include - Artificial Flow Path (used to show network connectivity through polygonal features), Ditch, Intermittent Stream, Perennial Stream, Pipeline, Polygonal Feature Limit (denotes a border of a polygonal feature that is not actually a shoreline, such as the edge of a sandy wash or the maximum extent of an ice mass), Stream Connector. DOW_NAME. This is the feature name found in the CDOW aquatic database. NAME. This is the feature name modified for cartographic purposes. STRAHLER. Stream order was calculated using the Strahler stream-ordering method. It was only applied to natural streams and associated artificial flow paths and on a case by case basis to ditches that maintained stream connectivity. HYDROCODE. Delineates the eight digit hydro unit code in which the stream arc segment falls. QUADCODE. Delineates the topographic Quad number in which the stream arc segment falls. SOURCE. CDOW, CFF or DLG-3. AREA_BIO. This field identifies the initials of the CDOW area biologist charged with managing the particular water. BRAID. This item identifies a stream braid. Arc attributes: STREAM feature items can be attributed as perennial or intermittent. Stream Connectors are features that are added to supplement existing voids in the data for downstream features. They are added so that they conform to natural features and contour lines. Stream to stream connecting features must be within 800 meters of each other. Stream to lake, or lake to lake connectors are added on a case-by-case basis to maintain the known connectivity of the hydro network. Connectors can be added through dams. Connectors are NOT added from stream to ditch, ditch to stream, after an intentional stream termination or when there are intentional breaks from stream diversions into ditch/canals. A stream with the attribute BRAID = 1 identifies a stream braid. When a stream forks downstream the braid attribute is assigned to the shortest and most insignificant fork. Only one stream of the fork is assigned the braid attribute. When a braided stream joins with another inflowing stream the new stream created does NOT get a braid attribute. DITCHES and PIPELINES are generally excluded from this stream ordered statewide network, unless they were pertinent to continuity of the stream network which was determined on an individual basis. These are features which break the contours, do not follow a natural stream channel, and are identified on the map as an aqueduct, tunnel, penstock, siphon, ditch or flume. ARTIFICIAL FLOW PATH (AFP's) are used to maintain the connectivity of water flow. All water features that flow into, out of, or through polygonal water bodies have a connecting AFP. More than one AFP can be found in a water body connecting all inflowing streams to the main flow artery. All head water bodies connecting an out-flowing feature have an AFP. All terminating water bodies connecting an inflowing water feature have an AFP. Artificial flow paths are used in washes and marshes to maintain connectivity when a stream would most likely flow through the water body. If a stream is delineated on the map in a wash, marsh, or inundation area the stream is left as is and AFP's are used to fill in the flow gaps. Artificial flow paths that fork downstream are considered braids. Only one of the forks receives a braid attribute BRAID = 1. AFP's connecting to ditches can also receive a braid attribute. AFP's are NOT found outside of a polygonal water body. Artificial flow paths are NOT used to maintain flow through dams. AFP's are NOT found in free standing polygonal water bodies. NAMES of arc water features are determined by what is named on the map. If a name is present it is attributed as NAME1 = (name on the map). In some cases the use of USGS GNISID name points were used to determine the extent of the stream name and to which forks the name applies. Names beginning with 'Mc' were changed so that there are no spaces in the name. For example, Mc Kenna Creek is changed to McKenna Creek. Streams, ditches, pipelines, and artificial flow paths are the only arc features that carry a name attribute. When a water feature has more than one name the least significant name is applied to the second attributing scheme. The second attribute scheme does NOT have to be populated with any other attributes if the water feature is the same. Artificial flow paths carry the stream, ditch, or canal name through lakes and polygonal water bodies. Headwater lake AFPs are NOT named. Features with a BRAID = 1 are NOT named unless it is unavoidable. Valleys and meadows, and other land features are NOT named.
