River Description

River Description
The Potomac River below Anglers Inn is an easier run than the Mather Gorge section just upstream, but is still in the back yard of Washington, D.C. This fact contributes to the strong boating community in the metropolitan region. In this section, the river maintains it's wild and remote feeling, except for at choice spots where Virginia has allowed sloppy development to mar the shore.
The river offers play and practice for beginners to experts and numerous sections can be run. This description will deal with the rapids and access points and doesn't provide details on the numerous play spots.  Make sure you know the take-out from the river - there is a dangerout low head dam downriver above Little Falls
- Angler's Inn. Put-in Reach via MacArthur Blvd. Park in one of three gravel or dirt lots across from the Angler's Inn, a fine restaurant. Carry across the canal, then 100 feet south on the towpath, then right down to the shore. From the river, the beach is easily seen on river left.
- Carderock. Reach via Clara Barton Parkway. Park at Carderock picnic area. Path across grassy area leads to small access. From the river, the access is a muddy bank.
- Lock 10. Take-out.  Reach via Clara Barton Parkway. Park at Lock 10 lot. Trail leads down to shore. From the river, you need to take a river left side channel to find the path.  Make sure you know the take-out from the river - there is a dangerout low head dam downriver above Little Falls.

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

Attention Virginia Boaters!

Jason Robertson

During the high waters of Spring 2003, there has been a noticeable increase in reported confrontations between boaters and property owners in Virginia. Please remember to be respectful and courteous to property owners; do not trespass; and avoid confrontation in order to preserve access in the future.
