ESRI shapefiles and SARIS lookup table (30 MB)
Overview
The Networked Hydro Centerlines layers were developed for use with the Watershed Analyst extension that was used in the now-discontinued ArcView GIS 3.x version of the MassGIS Data Viewer. The data were developed by watershed, divided into 32 tiles based on the SARIS (Streams and Rivers Information System) IDs of the Major Watersheds. Each tile name is a four-letter abbreviation of the basin name. The tiles are named as follows:
| SARIS ID | Major Basin Name | Tile Name |
| 11 | Hoosic | HOOS |
| 12 | Kinderhook | KIND |
| 13 | Bashbish | BASH |
| 21 | Housatonic | HOUS |
| 31 | Farmington | FARM |
| 32 | Westfield | WEST |
| 33 | Deerfield | DEER |
| 34 | Connecticut | CONN |
| 35 | Millers | MILL |
| 36 | Chicopee | CHIC |
| 41 | Quinebaug | QUIN |
| 42 | French | FREN |
| 51 | Blackstone | BLAC |
| 52 | Ten Mile | TENM |
| 53 | Narragansett Bay | NARR |
| 61 | Mount Hope Bay | HOPE |
| 62 | Taunton | TAUN |
| 71 | Mystic | MYST |
| 72 | Charles | CHAR |
| 73 | Neponset | NEPO |
| 74 | Weymouth & Weir | WEYW |
| 81 | Nashua | NASH |
| 82 | Concord | CONC |
| 83 | Shawsheen | SHAW |
| 84 | Merrimack | MERR |
| 91 | Parker | PARK |
| 92 | Ipswich | IPSW |
| 93 | North Shore (N.Coastal) | NCOA |
| 94 | South Shore (S. Coastal) | SCOA |
| 95 | Buzzards Bay | BUZZ |
| 96 | Cape Cod | CAPE |
| 97 | Islands | ISLA |
The networked centerline data, named HYDRONET_ARC, was developed for all watersheds except for Cape Cod and Islands. A route layer, named HYDRONET_RTE_SARISRT, contains only lines with a named SARIS route. The linework is dissolved on the SARISNAME field and is available for all land area within Massachusetts for all watersheds except Taunton, Buzzards Bay, Cape Cod, and Islands. The centerline was created and routed using a set of ARC/INFO AMLs from the 1:25,000 Hydrography as featured on the USGS topographic quads.

| SOURCE | Data source for coverage (100K enhanced or 25K DLG) |
| PWSID | DEP PWS ID number of downstream Public Surface Drinking Water Supply |
| CLASS | Designated Use Classification (not yet implemented; Mass. Surface Water Quality Standards) |
| ARC_CODE | Generalized arc code derived from MINOR_TOT |
| HYA | Generalized arc code derived from MINOR_TOT |
| RMIN | Minor_num of polygon to right of arc |
| LMIN | Minor_num of polygon to left of arc |
| RHYP | Generalized arc code to right of arc |
| LHYP | Generalized arc code to left of arc |
| CONNECTED | Arcs that are in the route system |
| SARISNAME | Name of stream or river based on SARIS system |
| ARCLINK | Links arc to its route in the section table |
| T_MEAS | Meters from mouth of routed major basin based on All route |
| SARISCODE | Stream code based on the SARIS (Stream and River Id System) |
The HYDRONET_RTE_SARISRT attribute table contains the following:
