From down south

If you are in the four corners area, Sand Hollow is a lot more than six miles away.

I would think your best bet in the area are some of the reservoirs around Blanding and Monticello.  There are the Blanding #3 and #4 Reservoirs, Recapture Reservoir a little further north, and Lloyd's Reservoir Reservoir near Monticello.  There also a couple of small lakes near Monticello, Foy Lake and Monticello Lake that have populations of fish.

Good luck!

Whoops, I meant six hours.
