Natural features

Aside from two campgrounds and a nearby day-use park, very little of the lakeshore is developed. The edges consist of rocky beaches and sandy bluffs. Although much of the lake area is forested, the campground has rolling hills that are mostly open with little to no shade. Most campsites have a view of the water, with some right along the shoreline and others within a short walking distance. The lake has noticeably clear and deep water that is inhabited by largemouth bass, smallmouth bass, channel catfish and many birds. A man-made wetland was constructed on the south shore of the lake to provide an additional 10 acres of wildlife habitat in the lake area.

Recreation

With 58 miles of shoreline, Stillhouse Hollow Lake is an often uncrowded haven for boaters and fishermen. The campground has a four-lane boat ramp, and visitors who do not have motor boats, canoes or kayaks can rent them nearby. Birding is also a favorite pastime, with hawks, Great Blue herons, ducks, geese, many species of songbirds, bobwhite quail, Rio Grande turkey and even an occasional bald eagle, yielding year-round opportunities for bird sightings.
