The USGS has a set of AML's to conflate NHD from the 100K features to
the 24K features. You can contact them from the above web site.
Good Luck,

I have worked with the Esri ArcHydro data model to improve the quality of the local data(creating a network and flow).
>My question is how to conflate the two datasets. Is it better to take an NHD file and spatially adjust it to match the local data? or Should the attributes only be transfered through reach files or another technique. Has anyone done a project similar to this and can offer advice or point out available resources, extentions, scripts etc....
