This data represents the 2004 Integrated Report final assessment results for conventionals, aquatic life, metals, toxics, fish advisories, and shellfish harvesting for rivers in New Jersey. Also included are data for location of the rivers, monitoring station where data came from, and parameters listed on the 1998 303(d) list (for conventionals, metals, and toxics only).
This data spatially represents the assessment results for all rivers in the state that were assessed. This coverage depicts spatial extent by associating a single sampling point to a river stretch and applying the assessment results to the waterbody. The methods used for the final results are explained in the NJDEP document, "Integrated Water Quality Monitoring and Assessment Methods." The explanation for the spatial extent method is explained in: Spatial Extent Assessment Methods - Section 7
2004 Integrated Report files retain the same basic content as the 2002 Integrated Report, with small changes in format. Some files were combined to consolidate information. For questions on metadata content, please contact Leigh Lager, NJDEP/BFBM 609-292-0427 or leigh.lager@dep.state.nj.us

Waterbody linework based on EPA Reach File Version 3.0 (RF3).
Linework is the USEPA Reach File 3.0 (RF3) hydrographic database. Assessment results were imported from NJDEP Water Assessment Team's data files of assessment results, and included verification check with approximately 50% of the entries.
Checked for duplicate segments, undershoots, and overshoots.
Blank entries for assessment results are unassessed parameters.
RF3 linework +- 35 ft

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. The assessment results were imported from the Water Assessment Team's data files and joined with the shapefile using the Station ID as the common attribute. Some river segments had to be split and new RF3 Reach IDs generated under the following circumstances: a) conventional spatial extent ended before the termination node of the river reach (occurred mostly when two sampling sites on same RF3 stream reach); b) tidal area split a river reach; or c) 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.
