Liberty Reservoir is a 3,100-acre manmade body of water nestled in between Baltimore and Carroll counties. The reservoir, along with Loch Raven and Pretty Boy reservoirs, is used to supply drinking water to 1.8 million people in Baltimore and portions of the surrounding region, including Anne Arundel, Baltimore, Howard and Carroll counties. The reservoir and the 9,200 acres of land surrounding it are owned by Baltimore. The city allows guests to use the reservoir and surrounding lands for recreational uses including hiking, bird watching, horseback riding, row and paddle boating, and even seasonal archery hunting. Although Liberty Reservoir features multiple trails, the city government has allowed equestrians and hikers to use the many fire roads as trails as well.
