(RKLD) advised that the lift gates are all open. He said they were concerned that if the open the wicket gates they could sustain damage, so they prefer not to open them.

It appears they are making a good faith effort to get this done as quickly as possible.

Given the facts as presented by Bill O'Connor and Mike Cain, and the need to give a speedy response so the work can be completed before water levels get out of hand I am going to recommend the following course of action.

Using riprap for backhoe access to the river should be used provided that is the fastest way to accomplish the work. The riprap needs to be clean (not a lot of fines) and removed immediately upon completion of the work. I am assuming that this work will be initiated tomorrow and completed soon after. The exception to this approval is if a barge could be brought in to be used as a work platform in the same timeframe, that option should be used.

We understand the water levels may rise above the authorized maximum until the work is completed. If it does not look like the work will be completed in the next 48 hours, we will need to explore other options to prevent water levels from getting too high.
