Temira has been talking about the flow rate below the John Day Dam. What is the best source for flow and what is the upper limit for good sailing conditions at Rufus? Anyone have any comments they would like to share in LESS THAN 500 words (you know who you are).

Here is the link I use:

In my experience, Rufus and The Wall are best when the flow is under 200 KCFS, but the swell (and sailing) can still be good in slightly higher flows as long as the wind is strong enough to overcome the current. When the flow gets close to 300 KCFS (or over) you should keep driving to Arlington or Roosevelt.

Based on the current forecast, I would plan on avoiding the Maryhill stretch of river until late June.

On a positive note, the high water seems to make for great swell at the Hatchery.

Blowing high 20s, low 30s at Rufus on Tuesday with a perfect direction but I just sat and watched. The current was about 300 and it was killing the swell. The west end of the Wall looked much better (from I-84 on the drive home). Maybe because it`s a few miles farther from the dam?

Another flow site, slightly easier to read.

Thanks for the reports philodog. Your comments are right on from what I've experienced. I didn't go to the Wall Tuesday because

said 300 and that's usually to much current. 280 can be OK.

I sailed Doug's yesterday 4 hours of 4.2 and 2 hours of 4.7. The swell got good from 4 to 6:30, but earlier in the day it was marginal.
