It used to be easier with the combination of the Dosewallips gauge (now gone) and North Fork Skokomish below Staircase (USGS).
Now I go off a precipitation reading and NF Skok level. I look for at least 2-3" rain within the last 24 hours with the NF Skokomish @...
- 1000-1200 expect low and bony (hard on boats)
- 1200-1400 good low level (maybe bony for some might be perfect for others) great first time level
- 1400-1600 medium (potential to be high, especially if 3+ inches rain in last 12-24) great first time follow someone level
- 1600-2000 medium-high or just high (probably not a good 1st time level) higher potential to be high
- 2000+ straight up high (even with previous runs, it becomes difficult to get a feel for the wood w/out lots of scouting)
Obviously if the level is going up, expect it to be higher, and if its dropping to be lower. Its a small drainage and reacts fast. The lake helps regulate this a bit, but not as much as I initially thought it would. Keep in mind snow level can take this run out fast even with the NF Skok showing levels are good.
As far as the SF Skokomish gauge is concerned, I think you might as well use the Skykomish. Although sometimes you get correlating gauge readings and levels on Jefferson, you're much more likely to have SF at 3000 and it be either way to high or way to low.
Here is the NF Skok USGS gauge I use:

Here is NF Skok prediction (helpful but iffy):

Precip Readings:
http://waterdata.usgs.gov/wa/nwis/uv/?site_no=12056500&PARAmeter_cd=00060,00065
- select 'precipitation' under 'available paramaters' then click 'go'
http://www.wrh.noaa.gov/mesowest/gmap.php?map=sew
-select precip on right side then find SKOW1 and/orJEFW1 on the map. JEFW1 is the most reliable.
Good luck and let me know if you're going. I'm always looking to get on this run.

Good beta D. Be great to hit it with you this fall! For us mortals, or those new to the run I'd probably adjust the range slightly, and suggest the following:
Low - 900
Med - 1300
High - 1700
Call Darren - 2000 and up :)
Of note, it seems like there's a correlation to the Duckabush gauge. Here's a few runs including that data point.....
This past Saturday 10/18/14 - Low level on Jefferson:
NF Skok = 970 - 920
SF Skok = 1,320 - 1,250
Duckabush = 2.36 - 2.26 or 659 - 618
2.5 inches of rain in the 24hrs prior
March 30, 2014 - Medium Level (probably some snow melt with rain)
NF Skok - 1300 - 1050
SF Skok - 1700 - 1500
Big Q - 1.95 / 2.0
Duckabush - 2.51 - 2.36
November 17, 2012 - High level on Jefferson
NF Skok = 2,000 - 1,700
SF Skok = Rising to 1,500
Big Q = 650 - 500
Duckabush = 4.1 - 3.4
2 - 2.5 inches of rain in the 12 - 15 hours prior
It's a great run....tough to catch, but worth the effort.
