They built most of the ramps on the lakes before the lakes were filled.
Lake Oroville has to be down about 150' before the main ramp is above the
waterline.

I've seen lots of landings, and it ranges from, "Boy, that's good" to "WTF
were they thinking?" I remember a tilt trailer I had on a boat in
Louisiana, and when you got to the end of the concrete, it dropped off, and
that was the only way to launch or recover. And even then, you had to be
spot on.
