About Big Run

Big Run State Park encompasses 300 acres at the northern end of the Savage River Reservoir in Garrett County, Maryland, representing one of the most remote and pristine natural areas in the state. The park lies entirely within the 54,000-acre Savage River State Forest, the largest contiguous forest in Maryland, providing visitors access to true Appalachian wilderness. Named for Big Run stream, which flows into the reservoir, the park offers a quiet retreat focused on primitive recreation and nature appreciation. The Savage River Reservoir, created in 1952 by damming the Savage River, serves as the centerpiece for water-based recreation in the area. The park's location in Maryland's Appalachian Plateau region provides distinctly different natural characteristics from the rest of the state, with cooler temperatures and northern forest species.

Wildlife Ecosystems

Big Run State Park and the surrounding Savage River State Forest support some of Maryland's most significant wildlife populations. Black bears thrive in this region, with an estimated 500 adult bears inhabiting the forest, representing Maryland's core bear population. White-tailed deer are abundant, while bobcats, though rarely seen, maintain a presence in the remote forest interior. Wild turkey and ruffed grouse provide upland hunting opportunities, while smaller mammals including raccoons, opossums, and various rodent species are common. The Savage River and its tributaries support exceptional aquatic ecosystems, including native brook trout and the rare hellbender salamander, one of North America's largest salamanders. Johnny darters, striped shiners, mottled sculpins, and stonecats represent some of the rare fish species inhabiting these clean, cold mountain streams.

Flora Ecosystems

The forests of Big Run State Park reflect the northern Appalachian character of Garrett County, with species composition distinct from lower-elevation Maryland forests. Mixed hardwoods dominate, including red maple, sugar maple, yellow birch, and American beech, with northern red oak prominent on drier ridges. Eastern hemlock, though threatened by the hemlock woolly adelgid, still occurs along stream corridors. The understory features rhododendron, mountain laurel, and blueberry shrubs. Forest floor vegetation includes a variety of ferns, particularly hay-scented fern and New York fern in more open areas. Spring wildflowers such as trillium, hepatica, and spring beauty bloom before the forest canopy fully leafs out. The reservoir's edge supports wetland communities with sedges, rushes, and moisture-loving shrubs adapted to fluctuating water levels.

Geology

Big Run State Park lies within the Appalachian Plateau physiographic province, characterized by gently folded sedimentary rocks distinctly different from the more intensely folded Ridge and Valley province to the east. The underlying bedrock consists primarily of shale, siltstone, and sandstone deposited during the Devonian and Pennsylvanian periods, approximately 300 to 400 million years ago. Regional folding has created elongated arches that expose older Devonian rocks at the surface, while coal-bearing strata of Pennsylvanian and Permian age are preserved in the synclinal basins. The Savage River has carved a deep valley through these sedimentary layers over millions of years. Garrett County contains Maryland's highest elevations, with nearby Backbone Mountain reaching 3,360 feet at Hoye-Crest, the highest point in the state.

Climate And Weather

Big Run State Park experiences a humid continental climate significantly cooler and snowier than most of Maryland due to its high elevation and inland location. Mean annual temperatures average around 48 degrees Fahrenheit, approximately 10 to 15 degrees cooler than eastern portions of the state. Winter brings substantial snowfall, with annual accumulations often exceeding 80 inches and occasionally reaching over 100 inches. The region falls within USDA Hardiness Zone 6b, reflecting the colder conditions that influence vegetation patterns. Summer temperatures are notably cooler than the rest of Maryland, with average highs in the low to mid-70s Fahrenheit, providing relief from the heat that grips lower elevations. The area experiences freeze-thaw cycles throughout much of winter and early spring, affecting road conditions and recreational access.

Human History

The Savage River region was home to Native American hunting parties for thousands of years before European settlement, though the rugged terrain discouraged permanent settlement. European settlers arrived in the 1700s, establishing small farms in the valleys while the forested uplands remained largely wild. The area's forests were heavily logged in the late 1800s and early 1900s to fuel the growing nation's demand for lumber and railroad ties. Coal mining also occurred in the region, though on a smaller scale than neighboring counties. The Civilian Conservation Corps (CCC) played a crucial role in the area during the 1930s, constructing trails, roads, and recreational facilities while working to restore the cutover forests. The CCC legacy remains visible today in the park's infrastructure and the surrounding forest's ongoing recovery.

Park History

Big Run State Park was established to provide public access to the recreational opportunities offered by the Savage River Reservoir and surrounding forest lands. The Savage River Dam, completed in 1952, created the 360-acre reservoir that serves as the park's centerpiece. The reservoir was built primarily for downstream flood control and to augment water supplies, though recreation emerged as an important secondary use. The park is managed as part of the larger Savage River State Forest, Maryland's largest state forest, which has been managed for sustainable forestry, wildlife habitat, and recreation since its establishment. The CCC-built Monroe Run Trail, with its crumbling bridge abutments, provides a tangible connection to the conservation work of the 1930s that helped establish public lands throughout the region.

Major Trails And Attractions

The Monroe Run Trail extends 4.6 miles through scenic forest terrain, featuring remnant bridge abutments from CCC-era construction that once connected roads through this remote area. The trail terminates near the Savage River Reservoir, providing access to the park's waterfront. The reservoir itself offers excellent fishing opportunities for walleye, largemouth bass, crappie, yellow perch, bluegill, and trout. Non-motorized boating and electric motoring are permitted on the reservoir, providing access to otherwise unreachable shoreline areas. Hunting is permitted in season throughout the surrounding state forest for white-tailed deer, black bear, wild turkey, and small game. Winter brings opportunities for snowshoeing and cross-country skiing along forest trails. The park's remote location provides exceptional opportunities for stargazing, far from urban light pollution.

Visitor Facilities And Travel

Big Run State Park offers primitive camping at designated sites, emphasizing a rustic outdoor experience consistent with the park's remote character. Facilities are minimal, reflecting the park's focus on primitive recreation and nature appreciation. The park is accessible via Route 495 from Deep Creek Lake area or via Route 40 from Frostburg, though winter travel may be challenging due to snow and ice. Boat launching facilities provide access to the Savage River Reservoir for fishing and paddling. No entrance fee is charged for day use. The nearest services, including fuel, food, and lodging, are available in the Deep Creek Lake resort area or the towns of Frostburg and Oakland. Visitors should be prepared for self-sufficient recreation in this remote setting.

Conservation And Sustainability

Conservation efforts in Big Run State Park and the surrounding Savage River State Forest focus on sustainable forestry practices, wildlife habitat management, and watershed protection. The forest provides critical habitat for Maryland's black bear population and serves as a source area for wildlife dispersing into surrounding landscapes. Stream conservation programs protect habitat for native brook trout and the endangered hellbender salamander. Invasive species management addresses threats to forest health from insects like the hemlock woolly adelgid and emerald ash borer. Sustainable timber harvesting practices balance wood production with wildlife habitat and recreational values. The forest plays an important role in maintaining water quality for the Savage River and downstream communities dependent on clean water resources.
