Boundary Waters Canoe Area information sites

I think possibly the simplest way to check conditions at a specific site in the BWCA is to contact them directly....here's a link to their website...

http://www.fs.fed.us/r9/forests/superior/bwcaw/

This is e-mail addy for Superior National Forest, which oversees the BWCA http://www.recreation.gov/permits/map_of_Boundary_Waters_Canoe_Area_Wilderness/r/wildernessAreaMap.do?page=map&contractCode=NRSO&parkId=72600&topTabIndex=Permits
