Terrace Reservoir is a lousy place. The road FR 205 is very bad - do not drive it past T. reservoir. This road should be closed. The reservoir itself is ugly - contaminated with mining waste. Says Mountain Man
All the outdoors amusing things in the San Juan and Jemez Mountains will keep you coming back time and again. Jacobs Hill is pretty and can be seen from Terrace Reservoir, and Terrace Dam is an interesting thing to check out. A short spree to Shillings
Spring is always worthwhile; Terrace Reservoir is good enough to spend more than a day at, Alamosa Campground is a good local campground.
