Obama’s herring: Removing dams on the Patapsco brings back a silvery little fish

Jim Thompson and William Harbold discovered silver in a place in the Patapsco River where it had not been seen in more than a century. The discovery occurred last Friday around 10 a.m. about 3 miles downstream of Ellicott City and just upstream of where the Bloede Dam used to be. As discoveries go, it was hardly sensational; it did not send shock waves through the stock exchange.
