I take it you dont haul your road bike up there? looks like a great trail. Lucky lucky man. 
It is a great trail. I have ridden it a number of times when I lived in Highlands Ranch. If you check out MTBR.com under the Waterton Canyon trail you'll see a variety of reviews. Most border on the negative side, but personally I think the trail is great. The real MTB starts after the dam. Quite a ascent and absolutely courgeous country.
