Description:

Hydronet_me24 and Hydropoly_me24 depict Maine's hydrography data, based on 8-digit hydrological unit codes (HUC's) at the 1:24,000 scale. Some New Hampshire and New Brunswick hydrography data are also included. The NHD hydrography data was compiled from previous ArcInfo library data for the state by 1:24,000 scale quadrangle. This data was subjected to several processes including edge-matching tiled data, adding photo-revisions and using available evidence or cartographic judgement, lines called connectors were added to join features that were deemed to have flow between each other. All arcs were directed downstream and artificial paths were created through 2-D waterbodies to complete flow through the hydrography network.
