That depends. There is no Standard for measuring rivers AFAIK.
"There is not yet full consistency or standardization of scientific terminology used to describe watercourses. A variety of symbols and schemes exist. Parameters based on mathematical formulae or numerical data vary as well, depending on the database used by the theorist."

It isn't as simple as it might seem. Yes, you can use a laser range finder and determine to the cm. how wide the river is where you are measuring, but is that the widest part of the river? What season is it? The Nile is little more then a creek in places during the dry season, but is a major water barrier during the flood season. Many rivers are like that. Plus any major river is subject to tidal flows where it empties into the sea. So what time of the day is a factor also.
Then there is to 'dry' part to consider. Rivers meander. Do you count the old width, or the new one?
I think the defining measurement should be the longest bridge across the river. But that is just my opinion, which means it and 5$US will get you a cup of coffee at Starbucks, if they are still in business when you read this.
