The National Waterway Network is a comprehensive network database of the nation's navigable waterways. The data set covers the 48 contiguous states plus the District of Columbia, Hawaii, Alaska, Puerto Rico and water links between. The nominal scale of the dataset varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters.

The Navigable Waterway Network Lines dataset is periodically updated by the United States Army Corp of Engineers (USACE) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The National Waterway Network (Lines) is a comprehensive network database of the Nation's navigable waterways. The dataset covers the 48 contiguous states plus the District of Columbia, Hawaii, Alaska, Puerto Rico and water links between. It consists of a line feature class of the National Waterway Network (NWN), which is based on a route feature class for the NWN update regions (“1†through “7†, as well as the open ocean region “0†) and route event table with linear referencing system measures for NWN links. This dataset is a feature class with associated measures (in miles) that are used for finding distances, locating features, and displaying route event layers. It was exported from this route event layer. The nominal scale of the dataset varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters. These data could be used for analytical studies of waterway performance, for compiling commodity flow statistics, and for mapping purposes.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows three condensed maps of waterways known to be navigable as of the late 1950s, or those which had been used for navigation in the past. However, the map does not proport to show all the waterways upon which navigation was possible. The map entitled Existing Canals shows all the canals in operation as of the late 1950s. Their evolution is shown on the inset diagram entitled Development of Canadian Canals which gives the dates of construction and operation depths of canals. Several small maps featuring the Trent Canal System, St. Peter's Canal and the Welland Canal are also included on this plate. The St. Lawrence Seaway map shows the state of the St. Lawrence River, including the old canal system, dykes, locks and dams, prior to the construction of the Seaway, which began in 1954. Areas of land that were to be flooded are indicated along with railways and highways which were to be relocated because of the flooding. Construction of the St. Lawrence Seaway concluded in 1959.

The National Waterway Network (NWN) is a geographic database of navigable waterways and channels in and around the United States, for analytical studies of navigation performance, for compiling commodity flow statistics, and for mapping purposes. The NWN is comprised of a link database and a node database. Links are line strings, which consist of beginning and end points (nodes) with intermediate vertices (shape points). Links represent either actual shipping lanes (i.e., channels, Intracoastal Waterways, sea lanes, rivers) or serve as representative paths in open water (where no defined shipping paths exist). Nodes may represent physical entities such as river confluence's, ports/facilities, and intermodal terminals, USACE nodes, or may be inserted for analytical purposes (i.e., to facilitate routing).

Navigable water, Minnesota represents Navigable waterway centerlines for all navigable waterways within the state of Minnesota. It originated as an arc coverage with the U. S. Army Corps of Engineers. Then MnDOT extracted the arcs that lay within the state boundary. A description of the Navigable water layer is included in Section 5 of this document - Entity and Attribute Overview.

Summary The RITA/BTS desires a single nationwide database that has polygons/attributes for major rivers and lakes, is consistent across state lines, and has the most accurate data available. This database will be used primarily for map production, basic queries, and will be distributed as part of the National Transportation Atlas Databases (NTAD) 2008. Description The hydro polygon/arc coverages were created using TIGER/LINE 2000 shapefile data gathered from ESRI's Geography Network. The individual county hydrography line shapefiles were processed into Arc/Info coverages and then appended together to create complete state coverages. They were then edited to remove unwanted features, leaving a state-by-state database of both important and navigable water features. Attributes were added to denote navigable features and names. Also, an attribute was added to the polygons to denote which were water and which were land features. The state databases were then appended together to create a single, nationwide hydrography network containing named arcs and polygons. These features also contain a state FIPS. Because some of the hydro features are represented by lines instead of polygons, the complete hydro dataset consists of 2 shapefiles, one for lines and one for polygons. They must be used together to paint a complete picture.

These two data-sets contain potentially navigable rivers for small and medium-sized boats in South-America depending on the topography, rainfall and potential evapotranspiration. Hence, it is an approximation of the location of navigable rivers, not an actual map of hidroways. Navigability is defined by the extent of a river which in this case (1) for small boats accounts to ~5-15 meters minimum extent and (2) for medium-sized boats ~30-40m meters minimum extent. The model data was parametrized and validated with land-cover data from high-resolution satellite images. Please see the full description of how the data-sets was created in the attached PDF File.

Navigable waterways. The source of data is based on the collection of historical maps and the Ryavec and Henderson (2017) shapefile of 1850 (https://doi.org/10.7910/DVN/8KHNVI). This collection contains very detailed maps of the navigable waterways of France over the second half of 19th century. I digitized the historical maps for the years 1860,1870,1880 and 1890 in QGIS. This dataset was used in https://doi.org/10.1080/00343404.2025.2511710

Contains 11,201 sequential mile positions of navigable inland waterways and the Gulf Intracoastal Waterway. Records include eight fields; id, latitude, longitude, mile, river code, river name, river number, source .

This database contains lines and polygons showing the locations of provincial waterways, such as drains, dikes, diversions, detention basins, floodways, dams and reservoirs. This dataset was created by digitizing high-resolution imagery of the water features and by digitizing the titled Water Control Work plans associated with the features for drains which have been designated as provincial waterways by Order-in-Council.This dataset was created to provide a record of the designated Provincial Waterways in Manitoba and was intended for use in administering Provincial Waterways Authorizations. Provincial Waterways are designated by Order-in-Council and are under the administration and control of Manitoba Infrastructure (MI) through the Water Resource Administration Act.

The Commissioner of the Department of Natural Resources through AS 38.04.062 (b) to compile, maintain, and make public a list and map of all water in the state that the commissioner, the United States Department of the Interior, Bureau of Land Management, or a state or federal court determines was navigable water at the time the state achieved statehood. The submerged land underlying that navigable water shall be included in the inventory of state land prepared uner AS 38.04.060. AS 38.04.062 (g)(1) "navigable water" means water that, at the time the state achieved statehood, was used, or was susceptible of being used, in its ordinary condition as a highway for commerce over which trade and travel were or could have been conducted in the customary modes of trade and travel on water; the use or potential use does not need to have been without difficulty, extensive, or long and continuous. The Navigable Waters datasets are a representation of those waterbodies where the DOI, BLM has made a determination of navigability and the State of Alaska concurs or disagrees. The datasets also include those waterbodies where title has positively been cleared through litigation or recordable disclaimer of interest. The datasets are continualy under consideration for edits and QA/QC. Many features have not been reviewed for QA/QC and are subject to change without notice. The database is not intended to be used for navigational purposes due to natural changes in the waters over time.
