If Google maps takes you down what looks like to be dirt roads, it will take you to a dead end where a sign states, "no trespassing". Take the "long" way around and you should be fine. Go to Fairview and take "Mormon Road" and you should fine what you are looking for. Otherwise, the place is great overall. Fun to fish at.
It is a reservoir in the desert...not much to see here. Boat ramps are available.
