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.

The hasp was broken in the last 24 hours. Please DO NOT PUT MONEY IN THE BOX UNTIL IT IS REPAIRED! To donate on line, please go to and put "Upper Yough Access" in the comment box. Memorial Day Weekend is coming up, and Deep Creek Hydro on Maryland's famous Upper Youghiogheny River will release on Sunday, May 26th, and Monday, May 27th from 10:00 AM until 1:00 PM. This marvelous stretch of expert-level whitewater draws hundreds of paddlers from all over the country. American Whitewater has worked closely with the Town of Friendsville and the State of Maryland to make river access hassle-free. Please remember that we are guests of the town of Friendsville. Use the paddler parking lot off Maple Street; do not park or take out on Water Street or Morris Street without permission from local residents. Be discrete; use the change house to get ready for the river. Remember that public drinking and rowdy behavior is not appreciated by nearby residents. Upstream, the Sang Run Access is owned by the State of Maryland and has been maintained by American Whitewater volunteers for almost 20 years. Please leave a donation in the fee box. $3 for a sin, go to gle use or $20 per season pays for the porta potty, gravel, and other expenses. The water has been running high for the past few weeks. Be careful and be safe!

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.
