The Mill River channel takes shape

Last week, construction crews finished roughing in the Mill River channel through the former impoundment.  The new channel has a gentle slope and meanders across the new floodplain.  The photo above gives a sense of the curves; this photo was taken from the mid-point of the impoundment looking downstream.  This week crews will begin constructing the stream banks by building burritos of soil.  Crews will also place gravel in the bed of the stream.
Meanwhile, the impoundment continues to green-up with pioneer wetland species and grasses.  "This looks better than my lawn," said one visitor.

The photo above was taken at the former dam looking upstream.  Again, you can get a sense of the sinuosity of the new channel as it winds off to the left.
