River is runnable as low as 350. Comfortable @750ish, Only problems are Ledge, Hard pull off the wall. Not impossible. One layover at that level (below 1,ooo) Government is the real problem. Straight ahead and ROWIN" is the way to do it. Right down the middle. Just right then left.
Anything over 1500 is straight forward.
Once you come around the corner @ slickhorn your on the LAKE.
Past Grand Gulch it gets really braided. Anything over 2,ooo you;ll be ok. under that????
Although under 750cfs. It;s actually easier. Cause you can read the water.( If ya know what yer doin)
My advice, Do the first strech in 2 days. Then make it past Mex Hat. continue to the first loop camp.lay-over then make it to johns. etc...
