Is Eleven Mile actually running?

[thecraw]

Looking at the gauge it appers that it's kicked into grear.

It's been a long time since I ran it and have no idea what the levels are needed to be for a good run. I do remember some fairly good rapids though...

I have no idea if it is in or not, but Marty if you go I will go with you.

I don't know what gauge you're looking at, it's currently rockin it at 35cfs...

phateye was down earlier, so I looked on AW and it was showing in the med level... weird.

I thought that looked strange.

OK... what the hell is going on here.

I am not sure what is up with the gauges as many on Eddy Flower are not consistent with long term well trusted ones such as AW. And for whatever reason when Phateye was taken over by EF many readings got instantly odd...

For instance... again with 11 mile, it is apparently running at a low but good flow of 230 as seen here:

But EF still shows it at like 43 cfs...

11 mile is a great run albeit many years since I have been on it.

Does anyone have a visual on this to confirm what is going on here?

It looks like AW is using the South Platte above Cheeseman Res for 11-mile. Wouldn't Lake George be a better gage?
Right now:
SP above 11-mile: 37.4 cfs
SP near Lake George: 39.6 cfs
SP above Cheesman: 211 cfs

Bottom line, I don't think 11-mile is running. Other bottom line, I seriously miss the old, simple Phateye. The DWR has updated their flows page and it's more updated and comprehensive that anything else I know of out there:
District Data

Happy floating!

Marty,

The eddyflower gauge is correct. It is the CO DWR gauge for the South Platte near Lake George. That is the flow through Elevenmile Canyon. Pauh of EF, if you are reading, it would probably be good to use this gauge for Cheesman too, or add it as a reference.

Essentially, the guage listed on AW is right above Cheesman Reservoir, and so it is catching all the low elevation streams that come in below Lake George, like Tarryall Creek. I would imagine that later in the summer, like June and July, these two gauges would be pretty similar because the main source of water would be discharge from Elevenmile Reservoir, not tributary runoff. The situation is similar to Waterton Canyon, when it is at 600cfs, but Bailey only has 100cfs or so--most water comes in from the little creeks.

A lot of the gauges on AW are well below the actual run and therefore they aren't the most accurate indicators. So, I would keep an eye on the South Platte near Lake George gauge to find out when Elevenmile or Cheeseman is in (Detail Graph).
