I haven't been on the river for two years now. We just started a contrct, or rather, resuming the run that we had 2 years ago but that only covers 4.7 miles of the river.

The Lower Mississippi River is good for awhile because the rains that have fallen over the last couple of weeks in the Lower Mississippi River Drainage Basin and Ohio River Drainage Basin.
I don't know what the largest allowable tow size at this time is.

The problem is the Upper MIssissippi River which is affected by the ongoing Mid West Drought in both the Upper Mississippi River and Missouri River Drainage Basins. Basically speaking, It's the Upper Mississippi River that is threatened by the water shortage. The largest tows that can navigate the Upper River, normally, is 25 barges.
