This data represents the 2002 Integrated Report final assessment results for conventional parameters, metals, aquatic life (based on DO), shellfish, and fish advisories in tidal rivers. The assessments are based on data from NJDEP Monitoring Networks, NY Harbor Monitoring, and DRBC. The following parameters were evaluated: pH, dissolved oxygen, fecal coliform, arsenic, cadmium, chromium, copper, lead, mercury, nickel, silver, zinc, as well as fish advisories and shellfish consumption status.
This data spatially represents the assessment results for conventionals. metals, aquatic life, shellfish, and fish advisories in tidal rivers. 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." Conventional Water Quality Parameters Asssessment - Section 4.1 Toxic Water Quality Parameters Assessment - Section 4.2 Recreational Designated Use Assessment - Section 5.2 Fish Consumption Designate Use Assessment - Section 5.4 Shellfish Harvesting Designated Use Assessment - Section 5.5 Spatial Extent Assessment Methods - Section 6

Waterbody linework based on EPA Reach File Version 3.0 (RF3).
Linework is the EPA Reach File 3.0 (RF3) hydrographic database. Assessment results were imported from NJDEP Water Assessment Team's data files, and included verification check with approximately 20% of the entries.
Checked for duplicate segments, undershoots, and overshoots. Also, ensured river segments ended at the head of tide.
Blank entries or "NA" for assessment results indicates unassessed parameter.
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 or RF3 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.
