Lewis and Clark data show a different Missouri River

aid. "The whole river is strapped in and the flow is much more variable now than then."

According to Ehlmann, the modern Missouri-Mississippi River confluence near St. Louis shows greater average daily stage change and greater standard deviation 8.5 +/- 14.4 inches at St. Charles and 9.1 +/-11.1 inches at St. Louis -- than did the river mouth at Camp Dubois (near St. Louis) in the winter of 1803-04 5 inches +/- 5.2 inches.

In contrast, she said, at present-day Washburn, North Dakota (Fort Mandan, two hundred years ago), normal daily variability is between 1 to approximately 4 inches compared with an average stage variability of 4.1 +/- 7.1 inches when Lewis and Clark made measurements. A few days, however, show extremely large variability, greater than 20 inches. This, said Ehlmann, is "due to regulation by huge, nearby main stem reservoirs."

The conclusion from Ehlmann and Criss's study is that "flow regulation by main stem reservoirs and numerous others on tributaries does not fully offset the large increases in flood stages and greater stage variability that are caused by channel restriction and development in the lower basin," according to the researchers.
