You can usually get North Branch and Savage reports at http://www.easterntrophies.com/. And as someone mentioned above, that Maryland stream guide has oodles of info. I usually fish the North Branch every year, and occasionally the Savage, so if you drop me a PM as your trip approaches I may be able to give you some advice. I believe the North Branch is one of the best tailwaters in the East.

Also, you may wanna check with the Maryland DNR to make sure they aren't doing any dam releases when you head out there. Occasionally they make whitewater in the spring and fall, but it's all scheduled.

Best,

Dave
