Hey iwindsurf,
Have you noticed the sporadic outages with the "new" Dougs 57A meter that have been happening this season?
Fortunately the old Dougs meter is still online and seems to be working fine. I'd say it gave a better picture of what I felt on the river this afternoon.

I was at Doug's the other day and folks were talking about the wind meter problem. The rumor is that a local Osprey has been using the arm of the meter as a perch at times. As the graph shows it was blowing 30+ today and suddenly it went to 1 mph...pretty weird, so the bird theory may be true. May have to send out my Panther to check it out

I found the note about the osprey on the website under "sensor notes".
If the cause of the drop outs can't be eliminated, maybe a link to the old Doug's sensor needs to be added back to the maps since it can be hard to find otherwise.

Hi Chris,
We're aware of the problem at Doug's 57A and we have new equipment headed out to the Northwest to address the problem. The anemometer was replaced last fall but the issue continued so we are replacing a couple of additional components in an attempt to bring sanity back to this sensor.
Placing sensors on navigational aids in the Gorge allows us to get some really incredible data for windsurfers / kiteboarders. Unfortunately we have to share our platforms with nesting osprey during the summer months. Each situation is a little different but ultimately they have right-of-way and can block access to our equipment.
We really, really, really want to solve problems when they pop up. We're going to do our best to solve the intermittent outages at both Doug's 57A and The Wall M40 but if we cannot access the nav-aids due to the presence of osprey then we'll have to wait until their young leave the nest.
Regards,
Stuart

This should answer the question as to why the sensor isn't consistent. Taken this afternoon at Doug's:

I also took photos of the osprey. There are the mom n dad and 1 baby. He sits right on top of the wind spinner cups

Wow, it's hard to believe he can land on that thing and hold it still in a 30mph wind. It looks like he just needs an alternate perch (that doesn't spin) above the anemometer.

Guys,
Thanks for your reconnaissance work! The plan is to replace the cup anemometer with a RM Young anemometer, which makes it very hard for birds to roost on. However, we can't perform any upgrades until osprey nesting season is over (usually in early September). This is because osprey are federally protected birds and regulations prohibit us from mounting navigational aids with active osprey nests. So, for the short-term we'll probably see the intermittent "outages" when osprey are protecting the next from the conveniently located roost. Then, sometime in September we'll upgrade the anemometer.
Sorry for this inconvenience! Lesson learned: never underestimate the osprey.

That has to be the most bada@$$ technical outage reason ever.
Every time I look at the Doug's 57 A sensor now, and see it plummet to zero, I'll smile thinking of an Osprey protecting his brood, and priming to launch a hunt for fish, for the greatest death from above display in the animal kingdom, except maybe full grown 4 foot bald eagles in Alaska plucking salmon twice their weight.
Ospreys, true Gorge O.G.s.
