The plan is to remove the Monument low dam and replace it with a Whitewater Park, with options for a smoother channel or a whitewater passage. These channels along the Great Miami River are part of the Greater Downtown Dayton Plan, which if you haven't checked it out yet, you should! http://www.downtowndayton.org/plan/ The ultimate goal of these new river passages is to create a more aesthetic and recreational use of the river downtown to attract people to the city while still keeping flood protection in mind.
The whole plan is very exciting, but I think that the Whitewater Parks are a great continuation of the conservation that Five Rivers MetroParks and MCD have always kept as a goal for the city of Dayton and Montgomery County.
Here's more on the Plans for the Whitewater Park specifically: http://www.downtowndayton.org/plan/rivers.html
(P.S. The renderings of potential projects are really cool, especially this! http://www.downtowndayton.org/pdfs/recommendations_rivers_appendix2.pdf)
Enjoy this beautiful fall weather!
