This data represents rivers in the 2002 Integrated Report. There are 7,840 miles of rivers and streams in addition to 675 miles of canals in New Jersey. Of these, 6,330 miles (81%) are non-tidal rivers, 1,520 miles (19%) are tidal rivers, and 197 river miles share a border with a neighboring state.
This data spatially represents the rivers (1:100,000 scale) in New Jersey and was used as the base coverage for rivers in the 2002 Integrated Report.

Waterbody linework based on EPA Reach File Version 3.0 (RF3).
Linework is the EPA Reach File 3.0 (RF3) hydrographic database. Verification checks with approximately 75% of the entries.
Checked that each RF3 river segment has a unique identification code. Removed all overlapping lines.
Delaware River and Hudson River are depicted as a center line and stream bank. The center line river segment was the river segment with the calculation of river miles. The stream bank is for visual purposes only and is depicted in the table as all capital letters and the waterbody is "L", indicating no calculations of river miles for these river segments.

RF3 used as the basis for linework.
EPA RF3 used as the base linework for the hydrography. The following edits were completed to improve and simplify the linework: a) lakes are represented by only one segment, one shoreline was deleted while the remaining shoreline represents lake as one line; b) canals of cranberry bogs were deleted (these are used for irrigation); c) type of waterbody (river, lake, canal) attribute was extensively edited based on NJDEP lakes, 1985 Land Use/Cover, and 1:24,000 hydrography coverages; d) added stream segments where sampling sites are located using 1:24,000 hydrography coverage; e) connected isolated stream segments if 1:24000 hydrography coverage showed a connection with rivers; and f) corrected river names. Some river segments had to be split and new RF3 Reach IDs generated under the if the tidal area split a river reach or a lake not depicted on the original RF3 coverage was corrected on the linework. Intersected coverage with watershed management area and HUC 11 coverages to identify which watershed management, HUC 11, HUC 8, and region stream segment located. SEE the document "Integrated Water Quality Monitoring and Assessment Methods" for the description of the spatial extent method.
