For Lake Chabot specifically, there are no par 5's on the back 9, just the one par 6.
Of the 3 par 5s on the front, #8 is the only one I could see this happening as it plays approx. 480 downhill. The other two play down to the bottom of the valley and back up the other side to the green. And given how wet the course usually is, I couldn't see anyone running a ball very far up the hills there.
