Don't even think about the NB... it's running MUDDY!!!! (and a wee bit swift) Give it about 2 weeks without rain. Best time to 'yak it up here would be when the Towanda guage reads 5' or lower. You can do at 7' with a 'yak... but that's not for a novice. If your skilled at 'yakking! 7' can be fun fishing.
Right now, it's 8.9' I wouldn't risk it. Some logs, brush, and stuff coming down the river right now.
