Wow, is the Potomac skanky these days.  The dearth of rain has brought the levels down and between the stagnant water and the heat, the algae and underwater growth is flourishing.  Here's a little meditation on the underwater growth. Many of these river shots are the product of my morning meditations by the river.  Over time I start to notice things externally (as I do internally) that I had not noticed before.

This image is from a pond.  Last year about three old trees came down, exposing the pond to sunlight.  The result is a permanent cover of algae and growth.
