Sending more green to our eyes

This is the Arrow Lakes Reservoir, where Columbia River water is collected and held in Canada under the Columbia River Treaty, for use downstream in the U.S.

One of the tell-tale signs of a reservoir is trees having fallen like soldiers along the unstable shoreline from the raising and lowering of the water for hydro-power and flood control.  The  beautiful blue-green colour soothes the battlefield.  In places all along the upper Columbia River, the plain old beautiful, watery-blue shifts to this stunning, spangled blue-with-green-added.  When fine silt suspends in the water, the light passing through bounces into the particles of silt, sending green back to our eyes.
