The small 3.5-acre lake at the confluence of Sassafras Run and Standing Stone Creek is not stocked, but those interested in catching a wily native brook trout would do well to bring their fishing gear. The stream below the dam is stocked in the spring. A unique center spillway which acts like a waterfall, is in operation from about April 15th through November 1st. On quiet evenings, muskrats can be seen on the lake and an occasional duck or goose visits the lake from time to time. Trapping is not permitted.
Wildlife is abundant in the area.
White-tailed deer, black bear, wild turkey, and many species of small game may be seen by the alert observer. Due to the small acreage, Penn Roosevelt State Park is closed to hunting. However, the surrounding Rothrock State Forest is open to hunting. The camping area makes an excellent base for a fall hunting trip. The Mid State Trail which bisects the park provides cross-country hiking in the Ridge and Valley Region of central Pennsylvania.
