Scott mentioned in another post that when you shoot a lot at one location you get a lot of image as that all look alike. It is fun to try to get some different backgrounds in order to change things up every once in a while. Although the dams are manmade they have become an integral part of the Bald Eagle habitat along the Upper Mississippi. Also the addition of the dam gives the image some local context.
Lovely and crisp images Dave. I liked the second for the action are those pink colours tents?, but first one is more interesting. You said it the though Dams goble up vast areas of forest the back waters do provide good habtate for the wild live. Here is one such place it has become home for Otter, fishing Eagle and in summer time hundreds of Elephants literally thousands of Indian Gaur will come together.
Unlike a lot of dams the ones on the Mississippi River do not create lakes. There are necessary to only to raise the river a few feet for navigation. These dams are referred to as Roller Dams. The Rollers are the red/pink areas in the background. They can be raised and lowered to control the rate of water flow and the depth of the river behind them. When the river rises to near flood level they can raise the Rollers completely out of the water so that the river can flow unimpeded.
The Upper Mississippi River has 27 Locks and Dams from Minnesota to St Louis.
One of these days I'm going to find a couple eagles to add to my library..Hoping that happens this winter out here in the Valley. #2 is outstanding... love the action and the colors in the background and water.
