River Description
Canoe tripping run (20 miles, at only 3 FPM average gradient). It may be possible to shorten the run a bit using alternate accesses.
'Grand Rapids' (at Lat/Lng 46.7640, -89.2717) is the whitewater highlight of the run.
USGS aerial image resolution on Google is quite good. Go to the 'Map' tab, click 'USGS Aerial', and double-click near (not 'on') any of the markers on the river (put-in, take-out, or Grand Rapids), then zoom in to maximum resolution, and do a 'virtual walk' of the river.

Grand Rapids
RapidDistance: 0 mi
This is the only marked, named rapids on this reach. We have no specific information on the nature of this rapids. However, from the 'Map' tab ('USGS Aerial' view, zoomed in to maximum resolution) it appears to be an area of rubble shoals, leading to an island (making for some likely 'constriction waves').
