[OSGeo-Discuss] OSGEO project based Web app for watershed land use?

[Fawcett, David (MPCA)]

I have seen a Web app that allows a user to click on a map and get land use information calculated for the upstream area.  It is based on some OSGEO projects and is quite a cool app.

I have found and lost the URL to this app several times.  If this sounds familiar, I would appreciate it if you could point me back there again...
