Upper Yough Access Guidelines and Fundraiser

6/30/2020
Charlie Walbridge

At Maryland's Upper Yough, one of the country's finest whitewater runs, American Whitewater has been maintaining the Sang Run Access for the past 20 years. With the 4th of July weekend coming up, a quick reminder that we are guests of the Town of Friendsville when we take out. In addition changing clothes discretely ad behaving respectfully, please observe social distancing during the pandemic. Garrett County has a low infection rate, and a mask when patronizing local businesses is the norm. We are also beginning our annual fundraiser to pay the expenses American Whitewater has at Sang Run. Out goal is $1,000, and we have already received $160. The Fee Box at Sang Run is still closed due to vandalism. We suggest $20 for the full season; $5 for one weekend. Please donate on line, or use the donation jar at the Wilderness Voyageurs shop at the takeout. Please go to https://www.americanwhitewater.org/content/Membership/donate/? and put "Upper Yough Access" in the comment box.

Don Millard - AW Super Upper Yough Access Volunteer!

6/25/2020
Charlie and Sandy Walbridge

American Whitewater super-volunteer Don Millard has been taking care of the Sang Run and Friendsville Access Areas on Maryland's Upper Youghioghenny River for the past several years. This bulds on a 2003 agreement between American Whitewater and Maryland State Parks, which owns the property. This year he rebuilt the change house and porta-pot shelter, set AW's sign back up, filled in potholes, and mowed acres of grass. He not only did the work, he donated the materials and machine time! This work givezs AW strong ties to the community (the place is also a fishing access) and local park managers. Also, thanks to him, boaters are not faced with a $5 access fee at both ends! Please remember, the pandemic is still on. Be smart. If you use the porta-pot, wash your hands or use sanitizer!

Potomac River Closure for Golfing Officials Sparks Controversy

7/20/2017
Kevin Colburn

Several newspapers reported this week that the Coast Guard is proposing to close a portion of a popular section of the Potomac River whenever high-ranking officials are playing golf at Trump National Golf Club. DC area paddlers quickly balked at the proposed new rule and Congressional leaders have joined them in pushing back against the proposal. The Coast Guard has posted their proposed closure rules, and an opportunity to comment online until August 9, 2017. Alternative approaches could allow both public use of the river and secure use of the private golf course.

Attention Virginia Boaters!

4/24/2003
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.
