Low water in the river apparently means more animals can exploit the environment below the dam. There are rocks to rest upon and pools of water where fish linger. The hot weather has stimulated luxuriant plant growth which provides forage for the mallards. I even spotted a large brown water snake the other evening. It was cruising the rocks at the face of the dam looking, I presume, for small fish. I did see a few darting black fish shapes leaping up at the face of the cascading water. So did an observant Great Blue Heron that perched a few feet from the snake (who seemed unaware of its presence!). The heron seemed equally curious about the snake (who was focused on the fish). That would be quite a meal if he could manage it!

| Here's that incredible water snake. He looked huge but was probably a meter long tip to tail. |

| I returned this morning (July 29, 2011) and was able to sketch a pair of juvenile Common Mergansers as they rested on a flat rock. Later, they hopped into the water and started foraging. |
