Echota Bend, Illinois River — Part 3

“But I also know that in places, the river still runs deep, and though I've floated it in these places, it hasn't revealed itself in such obvious ways. I know that it might be months -- years, even -- before I understand what it has to teach me. I still need to give myself over to the flow and pattern and rhythm of it to learn its lessons and hear its messages. The river is inside me now, I know, and I need only wait and see where the current takes me, and what lies beneath it.”

On July 4, 2004 the site experienced yet another flood with a peak flow of near 18,000 cfs.  The pictures shown below were taken on July 14, 2004.

Over all,  I would say that this has been a very successful project.  The high bank that was eroding at the rate of 10 feet per year has not eroded since the project was completed 7 years ago and the vanes combined with the altered radius have been very effective.  Fish studies (not reported here) have shown very high numbers of fish in the restored reach.

In every project, there seem to be things that I discover that I wish I would have done differently.  First, I would have installed rock vanes instead of root wads at the onset, but that is fairly obvious.   Second, I would have had Troy re-build the third vane as the angle from the bank is too steep.  This causes a backwater and a back eddy that are resulting in the only scour observed anywhere on the sight.  Other than that the only other thing I would like to see is less mowing (or weed eating) of the site, at least along and down the bank.
