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:
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.

The HYDRONET_RTE_SARISRT attribute table contains the following:
SARISCODE Stream code based on the SARIS (Stream and River Id System) LENGTH Length of the route in meters SARISNAME Name of stream or river based on SARIS system
