re: W/o looking it up, what's your guess to what the Red and Ouachita River rank in flow rate?

interesting data point.......the corps of engineers have monitored silt content in the Mississippi for the last hundred years and there was a big change in the 1950's. The monitored silt content dropped by 2/3 over that 10 year period. Sooo the lack of silt caused a big loss in coastal wetlands. What caused the siltation loss??? The corp did a big nation wide campaign to reduce muddy water runoff .
