Looked briefly but did not see whether this was out there or not - I'm wondering if there's documentation similar to the on-premise elevation profile service, but for watershed delineation. I'd be interested in testing out the functionality the Watershed geoprocessing service, but running it against more locally-derived elevation data.
Thanks

Search ArcScripts (BETA) seems to be the site to look though
Thanks Dan, will look into it!
