The arboretum at Tridelphia Reservoir was created during late 2015 and early 2016 and is located along the Pig Tail Trail. It was created by Eagle Scout Connor Bruce and was made possible by the help and support from the Washington Suburban Sanitary Commission, the Maryland Urban and Community Forest Committee, the Howard County Forestry Board, and Boy Scout Troop 649.
Along a 3/4 mile hike from a parking lot to a beautiful cove 20 different species of trees are identified and signed with Arbor Tags. Three trees are located in the parking lot and the rest are along the trail. These trees support the ecosystem of the Tridelphia Reservoir by providing food for squirrels and whitetail deer and shelter for birds. They also contribute to the quality of the 800 acres of land and 21 billion litres of water by slowing and filtering the water that enters the reservoir.
