Terry R. Maret, Jon Hortness, Douglas S. Ott
2006, Scientific Investigations Report 2006-5230
Anadromous fish populations in the Columbia River Basin have plummeted in the last 100 years. This severe decline led to Federal listing of Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) stocks as endangered or threatened under the Endangered Species Act (ESA) in the 1990s. Historically, the upper Salmon...

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...
