Estimated Perennial Streams in Idaho, indexed to the NHDPlus
Description
Perennial streams in Idaho have been
modeled using regression equations for 7-day, 2-year low flows (7Q2)
described in Wood and others (2009, U.S. Geological Survey Scientific
Investigations Report 2009-5015). The model produces "synthetic" streams
based on 10-meter resolution digitial elevation models that have been
processed to agree closely with 1:24,000-scale National Hydrography
Dataset flowlines. See Larger_Work_Citation report text for a complete
description of the modeling process.
In this dataset, the synthetic stream lines have been indexed to the
NHDPlus Version 01_02 (schema version 1, data version 2). Points along
the synthetic streams where 7Q2 model estimates exceeded 0.1 cubic feet
per second were snapped to the NHDPlus 1:100,000-scale flowlines, and
then traced downstream using the NHDPlus network. The data are presented
in the form of a dBase-format event table. The traced line events
correspond to synthetic stream lines having PerCode values of 2 or
3.
