Clarksville never was.
It used to be St Ansgar, Greene, Riceville, Rockwell-Swaledale, Nora Springs, North Central, Rockford, and NP. With all of the mergers (Allison and Greene, Rockwell with Sheffield, etc) program shares (North Butler and Clarksville wrestling for example) things are becoming more complicated. With districts and the constant mergers and shares, changing school sizes by the year, I really don't see a point in having conferences. As schools merge or share programs simply redistrict/class them and make schedules based on those districts.
The only schools conferences make sense for are the larger schools. Even then, they would be largely split into districts that would align with the geographical location of the conferences anyway. Just get rid of them and simplify everything for the schools, ADs, and everyone else.
