This data set was designed for cartographic presentation only and should not be used for hydrologic analysis.

1/31/08 - Removed USGS fields as this dataset has changed considerably from it's original USGS format - Turtle River spelling error corrected - Streams w/same flow type and feature type have been merged into single entities - Added Draw and Label fields to make it easier to symbolize - i.e. you can label the Missouri River centerline but not draw it - Changed field names to 10 characters or less for ease of conversion to shapefiles - Alias' added so above field name changes were easier to interpret The data set portrays the line water features (streams and shorelines) of North Dakota. The file was produced by joining the individual State hydrography layers from the 1:2,000,000-scale Digital Line Graph (DLG) data produced by the USGS. This data set was formerly distributed as Hydrography Features of the United States. This is a revised version of the November 1999 data set.
