River Description

This class I float section begins at the confluence of the North and South Branches of the Patapsco.  There is no road access to the confluence, but in a high water year such as 2018, when water is going over Liberty Dam, you can put in on the North Branch, just above Marriottsville Rd. to run a 2.5 mile stretch of the North Branch (also class I - although strainers are likely), to the confluence.  However, in a normal year, it's rare to see water going over Liberty Dam.  Another possibility is to put in 1.8 miles downstream of the confluence at Woodstock Road, leaving about a 5 mile run down to Daniels, but as of the end of December 2018, the Woodstock river access was still closed.    Yet another possibility is to put in on the South Branch and portage or run the Class IV "McKeldin Falls" (the "McKeldin Falls" section of the South Branch is covered in a separate AW listing).  Finally, you can hike in from either the North or South Branch crossings with Marriottsville Rd. on the park trails with your boat to the confluence (not my taste, but last time I was there I ran into someone doing exactly that).  A whitewater boater would not seek out this section, but it is run, so it's included for the sake of completeness.

Upper Yough Access Depends on Everyone

Charlie and Sandy Walbridge

Many thanks those who have contributed to AW's Sang Run Access Fund on line. We raised over $1200 to pay for the porta potty and gravel. Thanks to you, we've maintained this site for the State of Maryland for over 20 years! Let's also give a special shout out to Don Millard, who has cut the grass in both Friendsville and Sang Run for many years to keep our access costs low. If not for him you might see a parking fee of $5 a head at both ends! Jeff Macklin Photo
