Chemical and Hydrologic Assessment of the Caloosahatchee River Basin, Lake Okeechobee to Franklin Lock, Florida (open access)

Chemical and Hydrologic Assessment of the Caloosahatchee River Basin, Lake Okeechobee to Franklin Lock, Florida

From purpose and scope: The U.S. Geological Survey, in cooperation with Lee County, conducted an investigation of the river in 1976-79. This investigation was planned to provide a broader base if information than heretofore available on the freshwater resources of the Caloosahatchee River basin, and in particular to provide information on water-quality conditions with emphasis on nutrients and algal growth. In addition to data collected during 1976-79, some earlier data collected by the U.S. Geological Survey were included to evaluate annual variation and trends.
