River Description

 

Despite the uninspiring description in the Holbeck/Stanley ("bible").  This is a fantastic run.  Maybe even a classic now that is has an internet guage and predictable flows. Likely a great wintertime resource in addition to spring melt.
 
Character
IV - V Lo-Medium Volume Creek.  Pool drop in nature with some longer boulder gardens. Probably 20-25 great rapids, mix of boulder gardens, ledges, and even a few slides. A few good mini gorges in the first mile or two.  Run flattens out and runs thru a ~1/2 m developed area.  After the dam, the run gets a bit steeper and more frequent pool drop. Good Rapids all the way to the take-out.
 
At similar flows, SF T is:
1. Similar in difficulty but shorter than SF Feather.
2. Easier, more open, and higher quality than Lovers Leap.
3. Much longer and harder than Pauley/Lavazola.
Best comparision is a longer, no hike version of Canyon Creek (SF Yuba trib). 
  
Portages
2 Portages. 20-25' dam (looks runnable, I'll let you test for rebar) and a bigger drop multi-tier 35-40' drop somewhat similar to the "ugly duckling portage" on S Branch Feather. Do beware the obvious piton in the first significant drop of the run.
 
Logistics
Take Out = Rainbow Pool (just off of highway 120, just west of Cherry Lake Rd)
Put In = HWY 120 bridge ~6mi upstream of rainbow pool
Recommended Flows = 300-350 is ideal for first timers and/or the faint of heart.  Likely up to 600 if you are bold.
 
Is this run for me?
If you want to step up to class V creeking, hone your boat scouting and have a fun adventure, go get it at 350cfs or less. Everything looked portageable. If you don't have fun on the first mile, take out at Berkeley camp.
Playground for a confident class V boater.
If you are a class V+ boater and haven't done it, it's worth it. Fun but not overly challenging.
 

Note: the reach ID'ed by the lat/longitude coordinates is from Rte. 101 to the campground. However, it contains some flatwater. There's some pretty honking gradient from the campground to the main Tuolumne.
