Here is the NFAR at this moment from early October 2014. The site is USGS real time water flow data, it gives you a map of the USA, click on the state of interest, that single map will come up with hot data points, click California and the circle for the one for 11427000 NF American R at North Fork Dam CA and just start searching their historical data base. The 20,000 and 30,000 cfs values really stand out! I've been in the canyon in Feb 1963 with boulders bouncing on the river bottom, wall to wall milk chocolate brown water just ripping down river with 3'+ diameter trees floating past at a good clip. That was my first time in the canyon and I was hooked for life.
For the North Fork when the water is above 250 cfs a strong swimmer can not swim up river against the current and just crossing the river at that number is touchy. At about 150 cfs it becomes easy to do most anything you need to do but you should start filtering your drinking water if you take it from the river. At less than 100 cfs the algae really starts to grow but even at low flow levels the water temperature is still 54 F and that would be in July through August when it is hot in there. Be careful in there!......................63bkpkr
