Ruby Lake lies at an elevation of 6,000 feet in a closed basin and the refuge contains over 9,000 acres of lakes, ponds, and waterways intermixed with islands and bulrush stands to the south and manmade dike units to the north. Depths vary from several inches to 12 feet deep and game fish are comprised of largemouth bass, rainbow trout, tiger trout, brown trout, and brook trout. The average size for largemouth bass is around 11 inches and trout typically surpassed 15 inches. The normal bass fishing lures include crankbaits, topwater, rubber worms, and spinner baits as well as bass flies. Most forms of bait such as salmon eggs, nightcrawlers, and Power Bait work for trout as well as small spinners, spoons, and flies. Spring through early summer or fall is the best time to fish for trout, while bass fishing is usually good in spring through fall. A Forest Service campground is situated adjacent to Ruby Lake and there are several primitive camping sites scattered in the foothills along the west side. There are two boat ramps for South Lake, the Main Boat Landing and Narciss Boat landing.
