Representatives from the Rhode Island Department of Environmental Management contributed a substantial amount of time and salary towards quality review of the dataset. ESRI ArcCatalog 9.3.1.1850 File Geodatabase Feature Class features stored in an ESRI File Geodatabase format represent watershed boundaries digitized in compliance with the "Federal Standards for Delineation of Hydrologic Unit Boundaries; Verion 2, October1, 2004" The following topological reviews have been succesfully completed: Create a new topology inside this geodatabase feature dataset. Associate the arc, polygon and centroid feature classes with this topology. Rank the arc feature class with a 1. Rank the polygon feature class with a 2. Rank the centroid feature class with a 1. Apply topology rules to arcs and polygons: To the arcs, apply these rules: Must Not Overlap Must Not Intersect Must Not Have Dangles Must Not Have Pseudos Must Not Self-Overlap Must Not Self-Intersect Must be covered by boundary of (polygon file) To the polygons, apply these rules: Must Not Overlap Must Not Have Gaps Boundary must be covered by (arc file) All fields for all polygons in the polygon attribute table are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All fields for the lines in the arc attribute table are attributed. The lines adjacent to the universal polygon are attributed with a 0 for the hu_level. These cannot be attributed until the adjacent states complete their linework at which point the highest level of hydrologic unit can be determined. The accuracy of these maps is generally based on the contour information of corresponding DRGs. The differences in positional accuracy between the hydrologic unit boundaries and their digitized map locations has not been tested Hydrologic unit boundaries generally were digitized within 0.01 inches of their locations on the digitizing source. Edge match locations are exact because the data were extracted from a New England-based hydrologic units layer which had been electronically edge-matched.

The watersheds for these bay segments were delineated and digitized from paper copy topographic maps using Arc Info software by NRCS staff. (Narragansett Bay Project did not create metadata for the bay segment coverage.) withheld 1997 ArcInfo withheld Rhode Island Geographic Information System (RIGIS) coverages for Basins and Subbasins (S44hdb90 and S44hsb90) were modified to fit standards for HUC -- aggregation to create appropriate HUC levels. Documentation for the RIGIS coverages is poor, however the data was the result of a cooperative effort between NRCS (Warwick), USGS-Water Resource Division (Providence), RI Water Resource Board, RI Division of Statewide Planning and the RI Dept of Environmental Management Watershed boundaries were hand drafted onto mylar quad maps and manually digitized ArcInfo 1997 Data layer attribution, editing, review by RI/IRT NRCS and RIGIS personnel; USGS ArcInfo withheld 1998 Basin coverages from MA and CT were edge-matched to the RI HUC8. Since the Blackstone (?PJ - 2007) and Quinebaug Subbasins do not drain into RI, few subdivisions were made past the HUC8 level. HUC 10 and HUC 12 delineations were made by NRCS staff to match CT and MA HUC 10 and 12 delineations. On-screen digitizing was done over DRG basemap ArcInfo withheld 1998 Additional subdivisions were made in the Pawcatuck Subbasin from paper copy topographic maps using Arc Info software by NRCS staff to fit local needs and meet the HUC standards. ArcInfo withheld 1999 Review and editing/combining of smaller subwatersheds to better meet National Standard withheld 2000 ArcInfo Attribute edits to update layer to newest Hydrologic Unit Digitizing Standard ArcInfo withheld 2001 Draft HUC maps were presented to the major data users in the state for review. Agreement was reached among the agencies (local, state and federal) that the proposed 8, 10 and 12 level units met the standard for HUC with the exception of the coastal areas since the standard for the delineation of coastal areas has not been approved.

All work was performed in accordance with reguirements & standards set forth in the "Federal Standards for Delineation of Hydrologic Unit Boundaries; Version 2.0, October 1, 2004. All edits were reviewed and verified by the RI Dept of Environmental Management and the Warwick, RI office of NRCS. With one exception, the resulting watershed boundaries do not conflict with the certified WBD of neighboring states. The exception occurs in the 6th level watersheds identified as follows: 010900030207, 010900040401 and 010900030208. The areas draining to "Cranberry Ponds" and thence to "Happy Hollow Pond" required alteration and will need to be resolved with the certified WBD for Massachusetts.

Federal Standards for Delineation of Hydrologic Unit Boundaries Federal Standards for the Delineation of Hydrologic Unit Boundaries Please refer to the Entity and Attribute Overview for valid values This is a description of attributes by field from the Federal Standards for Delineation of Hydrologic Unit Boundaries 1) Polygon attributes Huc_8 : Eight Digit Hydrologic Unit Code A unique 8-digit code from the USGS map series "Hydrologic Unit Maps". The same number was used in every record that pertains to a subwatershed that resides within the same 8-digit sub-basin.Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Huc_10: Ten Digit Hydrologic Unit Code This field provides a unique 10-digit code for each watershed. This same number was used in every record that pertains to a subwatershed that resides within the same 10-digit watershed. Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Huc_12: Twelve Digit Hydrologic Unit Code This field provides a unique 12-digit code for each subwatershed. Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Acres: Acres Area of subwatershed including non-contributing areas calculated to acres as a whole number, no decimals. The "Acres" field was calculated from the "Area" field. States: States The "States" field includes the names of all state(s) that the subwatershed falls within. The 2-digit postal abbreviation in upper case and in alphabetical order was used, separated with a comma. Ncontrb_a: Non-Contributing Area Drainage areas that do not flow toward the outlet of any hydrologic unit are considered non-contributing. If a non-contributing area is on the boundary between two or more hydrologic units, the non-contributing area is associated with the hydrologic unit adjacent to the low point on the boundary. This attribute should be the total of the non-contributing areas within a hydrologic unit calculated in acres. Hu_10_ds: Fifth Level Downstream Hydrologic Unit Code This field has the 10-digit code of the 5th level hydrologic unit that is receiving the majority of the flow from the watershed that the 6th level HU falls within. Outlets created by ditching or other artificial drainage were not considered for this field. If an HU flows into an ocean or the Gulf of Mexico, this field was populated with "OCEAN" and if a HU flows into one of the Great Lakes the term "LAKE" was used. If a HU flows across international borders, "CANADA" or "MEXICO" was used depending on which country the HU drains into. If an HU is a closed basin, then the term "CLOSED BASIN"was used. Hu_10_name: Fifth Level Hydrologic Unit Name This field used officially recognized names only. This field was populated by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol". The name used to attribute the watershed was used only once within a 4th level unit. Hu_10_mod: Fifth Level Hydrologic Unit Modifications This field identifies any type of modifications to natural overland flow that alters the location of the hydrologic unit boundary for a 10-digit watershed. This field shows the most significant to least significant modification(s) to the watershed boundary. One or more of the following abbreviations was used. SC - Stormwater Canal ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Non-Contributing KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel DM - Dam at outlet or HU boundary OT - Other Hu_10_type: Fifth Level Hydrologic Unit Type This field was populated with the hydrologic unit type from the list provided that most closely identifies the watershed. S - "Standard" hydrologic unit - Any land HU with drainage flowing to a single outlet point, excluding non-contributing areas. This includes areas or small triangular wedges between adjacent HU's that remain after classic hydrologic units are delineated. Some examples include "true", "classic", "composite", and "remnant" hydrologic units. C - "Closed Basin" hydrologic unit - A drainage area that is 100% non-contributing. This means all surface flow is internal, no overland flow leaves the hydrologic unit through the outlet point. F - "Frontal" hydrologic unit - Areas along the coastline of lakes, oceans, bays, etc. that have more than one outlet. These HU's are predominantly land with some water areas at or near the outlet(s). W - "Water" hydrologic unit - Hydrologic units that are predominantly water with adjacent land areas, ex. lake, easturies, harbors. I - "Island" hydrologic unit - A hydrologic unit that is one or more islands and adjacent water out to the toe of the shore face. U - "Unclassified" hydrologic unit - A hydrologic unit that can't be defined or doesn't fit into one of the types that have been listed. Hu_12_ds: Sixth Level Downstream Hydrologic Unit Code This field was populated with the 12-digit code of the 6th level hydrologic unit that is receiving the majority of the flow from the subwatershed. Outlets created by ditching or other artificial drainage were not considered for this field. If a HU flows into an ocean or the Gulf of Mexico it was populate with "OCEAN" and if a HU flows into one of the Great Lakes the term "LAKE" was used. If a HU flows across international borders, "CANADA" or "MEXICO" was used depending on which country the HU drains into. If an HU is a closed basin, this field was populated with the term "CLOSED BASIN". Hu_12_name: Sixth Level Hydrologic Unit Name Officially recognized names were used in this field. This field was populated by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol". The name used to attribute the subwatershed was used only once within a 4th level unit. Hu_12_mod: Sixth Level Hydrologic Unit Modifications This field identifies any type of man-made modification(s) to natural overland flow that alters the location of the hydrologic unit boundary for a 12-digit subwatershed. One or more of the following abbreviations was chosen for this field. SC - Stormwater Canal ID - Irrigation Ditch IT - Interbasin Transfer BC - Barge Canal SD - Stormwater Ditch PD - Pipe Diversion CD - Channel Diversion NC - Non-Contributing KA - Karst LE - Levee NM - No Modifications OC - Overflow Channel DM - Dam at outlet or HU boundary OT - Other Hu_12_type: Sixth Level Hydrologic Unit Type This field was populated with the hydrologic unit type from the list provided that most closely identifies the subwatershed. S - "Standard" hydrologic unit - Any land HU with drainage flowing to a single outlet point, excluding non-contributing areas. This includes areas or small triangular wedges between adjacent HU's that remain after classic hydrologic units are delineated.

I - "Island" hydrologic unit - A hydrologic unit that is one or more islands and adjacent water out to the toe of the shore face. U - "Unclassified" hydrologic unit - A hydrologic unit that can't be defined or doesn't fit into one of the types that have been listed. 2) Line attributes Hu_level: Hydrologic Unit Level This field provides the means to create cartographically pleasing maps. This field is populated with the highest hydrologic unit level (smallest number) for the line (arc) represented by the record. The attribute was recorded using numbers 1 through 6 representing each level with 1 being the highest and 6 the lowest level. An example would be if a line represents a region, subregion, basin, subbasin, watershed, and subwatershed boundary, then this cell was populated with a 1 (Region). Below is a list of numbers used for each level. Level Digit# Name 1 2 Region 2 4 Subregion 3 6 Basin 4 8 Subbasin 5 10 Watershed 6 12 Subwatershed Linesource: Line Spatial Data Source The Linesource indicates the base map source(s) used to delineate at 1:24,000 scale. The field was populated using one of the standardized code(s) listed below. If more than one code was used, then a comma was used to separate the codes. TOPO24 - Delineation from hardcopy 1:24,000 scale topographic maps TOPO25 - Delineation from hardcopy 1:25,000 topgraphic maps, only Alaska and Caribbean TOPO63 - Delineation from hardcopy 1:63,360 topographic maps, only Alaska and Caribbean DRG24 - Delineation from 1:24,000 scale Digital Raster Graphics DRG25 - Delineation from 1:25,000 Digital Raster Graphics, only Alaska and Caribbean DRG63 - Delineation from 1:63,360 Digital Raster Graphics, only Alaska and Caribbean DEM10 - Derived from 10 meter Digital Elevation Model DEM30 - Derived from 30 meter Digital Elevation Model NED30 - Derived from 30 meter National Elevation Dateset Model EDNA30 - (formally NED-H), derived from 30 meter Elevation Derivatives for National Applications BATH"scale" (ex.
