This is a 1:2400 line coverage showing Indiana's Navigable Streams as defined and classified by the 1992 Natural Resources Commission report. This data set was updated May 2013 using the Natural Resources Commission Information Bulletin #3 posted 06/11/2008 and Jun 2017 using the Local Res NHD dataset from USGS.

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 Navigable Waterways dataset is as of October 24, 2018, and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics's (BTS's) National Transportation Atlas Database (NTAD). The National Waterway Network is a comprehensive network database of the nation's navigable waterways. 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. Metadata

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).

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.

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 GIS data depict navigational routes commonly used in Florida. Many of these routes are officially designated navigational channels or waterways. Others are just well known but unmarked pathways from one location to another. These data were digitized from NOAA Nautical charts (image files) of various dates and map scales, using most detailed charts for the area and feature of interest. Where depicted on the charts, channel centerlines and waterway routes were followed. Otherwise, AToNs depicted on the charts were used as guides to trace navigation pathways. This data set does not depict all navigational pathways but should serve as a start to a more comprehensive data set.

"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. [AS 38.04.062 (g)(1)]

Omission of any waters from this map is not intended as a designation that it is not navigable.

This map does not identify all navigable waters due to scales and/or data limitations. Further, water not included is not considered either navigable or non-navigable until the commissioner has made a determination as to its navigability at the time the state achieved statehood. In addition, the commissioner may make corrections and alterations of this map to maintain accuracy. [AS 38.08.062 (d)]

The State Lands Commission has prepared the Significant Lands Inventory (report) for the California Legislature as a general identification and classification of those unconveyed State school lands and tide and submerged lands which possess significant environmental values. The publication incorporates evaluated and pertinent comments received on the initial draft report which was circulated statewide in February 1975.The absence of a particular digitized waterway in the dataset does not mean that the State does not claim ownership of that parcel or waterway, or that such specific parcel or waterway has no significant environmental values. This dataset is not intended to establish ownership, only to identify those parcels which possess significant environmental values. Staff was unable to physically inventory all of the considered lands; instead, the advice and participation of those with known environmental expertise was utilized as additional to staff survey.Tide and submerged lands are digitized in the WaterBody and WaterLine feature classes; WaterLines for coastal areas, WaterBody for inland areas. Tide and submerged lands under the jurisdiction of the State Lands Commission are those sovereign lands received from the Federal Government by virtue of California's admission to the Union on an equal footing with the original States. Such lands, and State interest therein, are generally the lands waterward of the ordinary high water mark of the Pacific Ocean (seaward to a three-mile limit); tidal bays, sloughs, estuaries; and, navigable lakes and streams within the State.School Lands are digitized in the SchoolLand feature class. State school lands under the jurisdiction of the Commission are largely composed of the 16th and 36th sections of each township. The Federal Government transferred these lands to the State in 1853, in order to establish a financial foundation for a public school system. In cases where the 16th and 36th sections were mineral in character, incomplete as to acreage total, or already claimed or granted by the Federal Government, the State was permitted to select other lands "in lieu" of the specific sections.The public trust of commerce, navigation and fisheries which the State retains on patented sovereign lands should also be considered included in this inventory. Wherever a waterway, or body of water, is listed or mapped, the common trust state interest in patented sovereign lands, if any, is also included.The State Lands Commission emphasized when it adopted this report at its December 1, 1975 meeting that all tide and submerged lands are significant by the nature of their public ownership. Only because of the methodology used for this report are all of these waterways not specifically listed in this inventory.It is the intent of the State Lands Commission that the Significant Lands Inventory be periodically updated. This dataset should be considered informational, to assist the Legislature, the Commission, and the public in considering the environmental aspects of a proposed project and the significant values to be protected therein.
