Guys, super excited to hear that folks are interested in this project. This could be a real win for Lyons and Lyons kayaking.
A little history, the October Hole feature was originally designed by locals and built with concrete and rock (this is the upper feature). S2o has since looked at trying to help with it. We have been informed by the US Army Corps of Engineers that we will not be allowed to use concrete on that structure again. As such, we have largely avoided adjusting this feature itself. I believe that it is too steep and could do with some adjustment but, of course, then we would lose the concrete.
My Firm, S2o Design and Engineering has volunteered our time to rebuild the lower hole (sometimes called the November hole) for the Town of Lyons. This lower hole was never intended to be a play feature and does not consist of enough rock to create a durable structure (it has about half the rock it needs). As such, we rebuild it every couple of years. It was last rebuilt about three years ago. There is a plan to rebuild it again this year although I am not certain on dates.
Contrary to Matt Booth's (ERDVM1's) statements above, we would very much like to have a nice play hole at the October Hole and have tuned it to the greatest degree possible using the configuration of the lower structure (the November Hole) and the pool. In fact, the last time we did it I invited Matt Booth himself to sit in his playboat as we made all of the adjustments--which he did. We stopped when he was happy. Dane Jackson also came down to help.
You are all welcome to come out for the second rebuilding of this structure which, I am assuming, will happen soon. We would be happy to adjust the structure to your liking.
