Designated as a State Scenic River in 1974, the Monocacy originates near the Pennsylvania border at the confluence of Marsh Creek and Rock Creek, flowing for 58 miles before joining the Potomac River. As the largest Maryland tributary to the Potomac, the Monocacy watershed covers 974 square miles across Frederick County, Carroll County, and portions of Adams County, Pennsylvania. The river varies in width from 40 to 375 feet and flows gently with an average gradient of 3 percent.

Maryland Stream Access Laws

Current law in Maryland seems quite friendly to public access to floatable water, allowing access at all public bridges and road crossings of floatable water. Though historically the state has only recognized waters subject to the ebb and flow of tides as navigable, that definition appears to have broadened. A complete list of public waters and access points is available on the Maryland DNR website.
