this thread is a bit old but for those that are still interested:
we had a little rain and snow event last night and there is a bit of a warming trend coming for az.
we watch the low temps in flagstaff as an indicater. lows 32 or above usually mean the salt and verde will rise. that's what it looks like for the coming week starting sat or sunday. by sat or sun night the trend should be apparent (up or down or not at all)
these are the two sites you can use for readings.
one will give you graphs for the white and black rivers which combine to form the salt. the readings are just above the confluence. you can add the two lower readings and add corrizo creek to get an idea of where the upper salt reading will be in a day or two.
will give you some forecasts but are not be-all-end-all readings. is seems that they don't always figure in rising temps in the forecasts.

i am, in no way, an official voice of the forest service but i did chat with the ranger last week regarding launches on the salt before permit season (begins March 1).
he said that if you want to go, you still need to enter the wilderness area (below Gleason Flats) before march 1. that means you need to launch on or before Feb 27 to be legal. all regs still apply: toilts, fire pans, trash etc.
lets hope it comes up. maybe we'll see you there.
