1999, Water-Resources Investigations Report 98-4223
The Elwha River was once famous for its 10 runs of anadromous salmon which included chinook that reportedly exceeded 45 kilograms. These runs either ceased to exist or were significantly depleted after the construction of the Elwha (1912) and Glines Canyon (1927) Dams, which resulted in the blockage of more...

Ground-water discharge and nitrate loadings to the coastal bays of Maryland
Jonathan J.A. Dillow, Earl A. Greene
1999, Water-Resources Investigations Report 99-4167
Nitrate in ground water discharged to the Atlantic coastal bays of Maryland enhances the growth of phytoplankton and algae in the bays, which in turn contributes to the process of eutrophication (changes in a body of water as nutrients and sediments accumulate), which is one of the principal environmental problems...
