The Hudson River is Reddish-Brown
I was amazed that a week after Irene the Hudson River was still reddish-brown with silt. This photo, taken with my IPhone looking down at a marina on the west side of the river, shows the color accurately.
How does all that silt affect the river's fish? I'll have to ask Tom Lake or Steve Stanne, editors and compilers of the Hudson River Almanac for the state's Hudson River Estuary Program.
