Description:
Abstract:
This dataset contains EPA River Reach data for streams, wide rivers, reservoirs, lakes, miscellaneous hydrographic features, and the coastal shorelines for the Atlantic Ocean and Gulf of Mexico.
Purpose:
The structure and content of the Reach File databases were created expressly to establish hydrologic ordering, to perform hydrologic navigation for modeling applications, and to provide a unique identifier for each surface water feature, i.e., reach codes.

Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: <http://geoplan.ufl.edu/education.html>. These data are based on interpretation of available information and should not be construed as legally binding.

Logical_Consistency_Report:
Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."

Attribute_Definition:
Marker Index; assigned to each piece of segments that are divided by a new tributary. Their segment numbers remain the same, thus identifying them as once being a single reach. The new downstream piece receives a marker index of zero. The new upstream piece receives a marker index which is defined as the proration or ratio of the distance from the base of the reach segment to the point of subdivision to the total length of the reach segment. DO NOT USE THE MARKER INDEX AS AN INDICATOR OF ACTUAL REACH LENGTH. The only valid use of the Marker Indicator is as a coding approach that enables the pieces with in one Segment to be hydrologically ordered.

Primary name. For connected reaches, including open water reaches, this is a stream name. Each connected shoreline reach around an open waterbody will bear the name of the stream which feeds that open waterbody.

For example, a Back Creek in Virginia would have a different PNMCD from any other Back Creek in Virginia or any other state.

Attribute:
Attribute_Label: SEGL
Attribute_Definition:
Reach length (Miles). This length was calculated from all of the latitude/longitude coordinate values for the entire length of the reach. NOTE: The difference between MI and UPMI will NOT always equal SEGL. MI/UPMI are proportionally related indexes based upon mileage calculations from RF1/RF2 and the DLG. For all mileage calculations, SEGL should be used.
