Senior Health - Water Aerobics Classes

We are in Choctaw, OK...  Looking for a water aerobics class for seniors for my husband.  Does anyone know if there are any options in our area other than the YMCA?  Apparently the high school used to do this... but no more.  Also looks like one of the junior colleges might do it but I can't get anyone on the phone to find out.  Any info members can find will be appreciated.
