I'd skip the spillway as a primary overflow for the pond and keep it as a secondary (or emergency) overflow. Too many have washed away that weren't properly constructed and sloped. You have to keep the water flow under "X" depth and under "X" speed to stop it from eroding. Yes, to the constantly wet comment too. If you want to mow it, and you leave a bunch of furrows from the tires, how would you smooth it back out? I have heard of spillways that were made of concrete wash away because the water somehow got under the concrete and washed the dirt away, making the concrete fail.

I took the bypass around Ft. Wayne today on my way to the Dayton, OH area.

To stop any problems with the freeze/thaw issue with the overflow pipe, put the winter aerator near the overflow pipe so it keeps the ice thawed in that area. Problem solved.
