The ROTten contingent of the FOGBEES (who post their morning rides under the FB Ride Group TAB) make frequent (almost weekly) trips to the Nashville Greenway. On our trip last week we were seriously flooded out. To avoid this problem in the future, we have added a tailwater level link in the sidebar on this blog. We guess that 398 is the magic number for a dry trail. Last week it was at 401.5 feet.

This past Sunday July 19 at about 10:00am I pedaled by last week's deeply flooded (1.5 ft?) greenway length; the river surface appeared to be a couple of feet below the pavement. Your link reported tailwater level 394.38 at that time and date. Assuming a 1.5 to 2 ft drop in the slope of the river from the tailwater to our deeply flooded section (and maybe 2.5 ft drop at last week's 401.5 ft tailwater elevation), it appears that your 398 ft is a good galoshes alarm elevation. My crude observations Sunday (and the water depth around the shapely legs of last week's lady wader) suggest the deeply flooded greenway pavement elevation may be around 397.5 ft as a guesstimate.
