Greenwood Reservoir, Upper Michigan?

Anybody been to the Greenwood Reservoir near Ishpeming in the U.P. of Michigan? I am having trouble finding any detailed maps, campsite info, etc. Plenty of fishing data is available, tho! Our group is experienced, well equipped, and do not need any outfitter-type of help, just looking for planning info to set up a weeklong summer 2013 trip.

Thanks, Jim & partners

Googling brought some info, but I didn’t
notice personal reports. My approach to such is to see if the Google Earth space photography is clear enough to scout and examine campsites.

The reservoir looks complex and interesting. Its watershed isn’t very big, but in spring and early summer it should be full and cold.
