River Description

Extremely hard to catch. Very flashy. The run takes a super cell of rain in a short amount of time. It doesn't have to be alot, just sustained hard rain for a decent amount of time - around 30 minutes. You must be very spontanious and in the area to catch it.

Put-in is right after it goes under Military Road. This is all park land. There is one significant drop before it starts droppin under the George Washington Parkway. This is "Pump House Falls" which is just a 10 foot drop with a sticky hole at the bottom. The George consists of three main drops all of which are unnamed.

I believe I am the only person to have ever run this, please correct me if I am wrong. I have only run it twice begining with a run in 2003. The stream is very fast, has few eddys, and is very prone to wood jams and strainers. Scout all main drops. The rapids in the George are constently reconfigured due to log jams.
