The Middle Cranberry will probably be around 3.0-3.3ft tomorrow afternoon, which makes for a very low and scrapey paddling experience.  The Lower Cranberry is still scrapeable at that level.  I like to see at least 3.8 as a bare min. for the Middle section.  Last weekend I had two laps at 4.5ft with nobody on the river until late afternoon.
