Water-level decline in the Apalachicola River, Florida, from 1954 to 2004, and effects on floodplain habitats
Helen M. Light, Kirk R. Vincent, Melanie R. Darst, Franklin D. Price
2006, Scientific Investigations Report 2006-5173
From 1954 to 2004, water levels declined in the nontidal reach of the Apalachicola River, Florida, as a result of long-term changes in stage-discharge relations. Channel widening and deepening, which occurred throughout much of the river, apparently caused the declines. The period of most rapid channel enlargement began in 1954...
