I have a question for anyone that has experence with a "Roller dam".
Our city is making plans to fill the lower side of our roller dam with large rock to do two things 1) make the roller dam safer by eliminating the roller effect and 2) make a "white water rapids" for recreation purposes.
My question is; What are the effects of doing this. I certainly think the hydronics of the river would change. My fear is that raising the river bed would raise the water surface elevation, potentially causing flooding downstream. ie the river banks are not high enough to contain the water during spring high water or flooding periods.
Has anyone had this done in there citys?
Also a man that has been in the mix of doing this to 40 other dams in MN said it would improve the fishing on the lower side of the dam and it would not effect the upstream enviroment at all. Is there any truth to this?
My home is only 1' above the 100yr flood plain and I may have real concern if the flood plain would change because of there actions($1,700.00 per yr flood ins)
