Keystone Reservoir
Armstrong
DESCRIPTION: Keystone Lake, a large reservoir owned by a conglomeration of utility companies and administered by the PFBC, is open and free to the public. Spring is a great time to see waterfowl and warblers. Summer is sometimes not productive because this is primarily a recreational lake and attracts crowds of people, including boaters and fishermen. Late summer and fall are prime times to search the various mudflats for shorebirds. The lake freezes over in winter, but the surrounding areas can sometimes be worthwhile for raptors and sparrows.

DIRECTIONS: From Indiana, take US 422 eleven miles west to Elderton; turn northwest (right) on PA 210 and proceed to the breast of the dam (1), a distance of 3.3 miles. Many vantage points are available along PA 210, but the most consistent are mentioned here. From the breast of the dam, proceed 2.5 miles to a dirt-gravel parking area (2) on the left. Check the scrub growth here in spring and fall for migrant passerines. Scope the lake for loons, mergansers, and scoters. Occasionally, large flocks of diving ducks are spotted here as well. Continue north on PA 210 for 0.3 mile to a sign indicating the town of Atwood to the right. Turn left here into the boat launch area (3). Park in the lower lot nearest the lake. Check the coves on the opposite shore for waterfowl. In spring be sure to walk right up to the edge and look down. Spotted Sandpiper frequent the water's edge, and all six swallow species have been recorded here. They frequently perch on the branches just below the lot. Both Purple and House finches nest in the conifers on the hillside. Continue north on PA 210 for 0.9 mile. Turn right and park along the dirt road named North Jefferson Street. Check the marshy area (4) to your right for Wood Duck and Mallard. Walk back and scope the lake. The muddy edges below are sometimes productive for shorebirds, especially during falls when the water level is low. Check the opposite shore for herons and the trees on the other side for a perched Osprey. Continue north along PA 210 for 0.9 mile. A dirt road (5) to the left leads to the water's edge. Do not drive all the way to the water—park and walk—as you are less likely to flush the birds here. This has been the best fall location for shorebirds. White-rumped, Baird's, and Stilt sandpipers have all been found here. To your right is a ridge of trees. Quietly climb the steep path for a better vantage point. American Bittern, Great Egret, Little Blue Heron, Black-crowned Night-Heron, and Double-crested Cormorant have been found here. Virginia Rail and Sora have been heard calling from the marsh. In fall, Green Heron and Killdeer are abundant. Check the snags in the water for a perched Belted Kingfisher. Return to PA 210 and again head north (left). After a quarter mile, turn left on Fisher Farm Road (before the Silver Canoe Campground sign where a small sign indicates "Keystone Lake West Side"). Pull off the road where the marsh becomes visible (6). Willow Flycatcher, Yellow Warbler and Swamp Sparrow are a few of the species that breed here. The courtship flight of the American Woodcock can be observed here at dawn and dusk. Wild Turkey have occasionally been seen along this road. 0.8 mile beyond the intersection with PA 210, there is a parking area (7) on the left. Park here and follow the abandoned road to the lake. The mud flats here are sometimes alive with shorebirds. Species recorded here in fall include Ruddy Turnstone, Dunlin, Short-billed Dowitcher, and Wilson's Snipe. In fall and winter, the shrubs harbor mixed flocks of sparrows. In spring and summer, Blue-winged, Golden-winged, and Prairie warblers can be heard singing from the parking area. Brewster's, too, has been listed here. A walk from the parking lot along the main road all the way to the open fields has produced a wide variety of flycatchers, vireos, and warblers in both spring and fall. Some of the roads in this section of Armstrong County are dirt and/or gravel. In wet weather, the rest of this tour is not recommended as dirt readily turns to mud which can be worse than ice. In dry weather, however, there is no reason not to continue. Return to your car and proceed along Fisher Farm Road another 1.8 miles to a T intersection and turn left onto Sagamore Road. After 0.3 miles, turn left onto Owl Hollow Road. At a sign that indicates, "No Outlet" Fawn Road continues straight ahead, but stay on Owl Hollow Road which bears right. At the next intersection, 0.3 mile beyond the sign, bear left, staying on Owl Hollow. Continue for another 1.2 miles. Just beyond a mailbox is a small parking area. Park here (8) and hike the remainder of the road to the lake. Ruffed Grouse and Pileated Woodpecker are often heard and occasionally seen. Acadian Flycatcher and Rose-breasted Grosbeak nest here. As soon as you can see the water, watch for Wood Duck and Mallard. Frequently in spring Green-winged Teal and American Wigeon are observed here. Return to your car and retrace your route for 0.6 mile. Turn left onto Fall Road. Listen for Grasshopper Sparrow as you pass the fields. After 0.5 mile, turn left at the T intersection where Winter Road turns right. At the next T intersection (another 0.6 mile) turn left on Summer Road. At the stop sign Summer Road merges with White Oak Road. This road ends after 2.2 miles at the parking lot for another boat launch (9). Pine Warbler and Red-breasted Nuthatch frequent the pines near the parking lot. Check the lake again for waterfowl. Pied-billed and Horned grebes are often reported from this vantage point. Once again retrace your route 1.4 miles from the parking lot and bear left staying on White Oak Road. After 0.5 mile turn left then immediately left again onto a gravel road named Spring Road. Continue 1.5 miles to the next T-intersection and turn left. This stop in Reefer's Cove is not recommended unless you have four-wheel drive or the roads are completely dry as this road has seriously deteriorated with large potholes filled with water. If, however, you do continue, the road leads to another small parking area (11) after 0.8 mile. It may be possible to pull off along Reefer Hollow Road and walk into the cove. As you approach, watch for herons flushing. Park and explore this last stop on the Keystone tour. Black-throated Green Warbler nest in the conifers across the cove. White-eyed Vireo breed in the scrub growth on the west side of the cove. Watch overhead for soaring Turkey Vulture and Broad-winged and Red-tailed hawks. A myriad of waterfowl have been observed from this spot in both spring and fall. To return to Indiana, retrace your route to the previous intersection and turn left. Proceed to the T-intersection and turn left on Cessna Run Road. Follow Cessna Run for 3.8 miles to a stop sign. Turn left onto SR 2003. Continue 0.8 mile to the stop sign in Gastown. Turn right and follow this road to another intersection where a left will return you to PA 210. Turn right and follow PA 210 to US 422. Turn left on US 422 toward Indiana. Sturdy hiking boots are recommended for any of the walks into the area, as it is frequently very muddy.
