Yes, Herrington did have Stripers (Striped Bass) at one time, but they failed to become a long lasting deal. I did "hang" one, out in front of the buoys at the mouth of Cane Run Creek, and battled with it for several minutes before it came unbuttoned .... straightening out the hooks on the Silver Buddy I was throwing.
I know what you mean about the "grass/moss" at Cedar ... and it's one reason I don't fish Cave Run as much as I used to. I used to think it'd be nice to have "pads" or "grass" at Taylorsville, but after seeing what happens at Cedar & Cave Run ... not so much, anymore. They did "consider" planting them at Taylorsville, but the constant flooding wouldn't allow it to grow.
