5/19 update...

Looks like they are turning down the tunnel to 200 cfs, about 245 in the river. Pretty low, but I did it at this level recently and still had a good time.

It's raining a fair bit in Denver and the plains, which will likely reduce demand for water. They might turn the tunnel down again tomorrow. If you paddle Sunday, I'd recommend an early start. They changed the tunnel at 9am today, and it's taking 4 hrs lag for flow changes to get from the tunnel to Bailey, so flows drop at the put in around 1pm. Putting on a few hours before 1 should keep you ahead of a potential flow drop Sunday.

Denver water turned down the tunnel to 150 this weekend. They dont plan to change flows today, but expect flows could go up tomorrow after today's warm weather. Might bump the tunnel back up to 200 to 250.

5/22 Update...

Denver Water turned up the tunnel today to about 175 cfs. Small increase. They expect flows to hold there until wed afternoon or thur morning. They are doing some maintenance on the tunnel that requires them to drop the tunnel to 70 cfs. They can't drop it in one big dip, so they are planning on dropping it in chunks. They think that the first drop might be wed afternoon around 3:30-4PM. If you are hitting bailey after work wed, check flows to make sure they didn't turn down the tunnel early. Its about a 4 hr lag from the tunnel to bailey right now, so if they turn it down at 3:30, you should have higher flows until 7:30 at the put in. After work should be ok, but check to make sure they don't turn down the tunnel earlier in the day and hose the afterwork.

After the maintenance they will ramp back up to normal flows. They are expecting 200's.

I'm out of town this wednesday through the weekend, but will have Kevin check with Denver Water friday to get the memmorial weekend flow beta.

Are they performing more maintenance this weekend? They dropped the flow dramatically. Not looking good for the holiday weekend.

5/25 Update

Ian's out of town sipping wine, but as his substitute, I called Denver Water this morning. They're currently releasing about 100 cfs from the tunnel and don't anticipate increasing it much over the holiday weekend. He said it's possible that they'd bump it up to 150 cfs, but something would have to change dramatically for it to go higher than that.

The bottom line is to look elsewhere for water over the weekend.

Kevin, you must not know how to ask nicely. DW always turns up the tunnel for Ian.

Denver water turned up the tunnel to 275 cfs today. Looks like about 315 in the river at grant. Good enough for me!

Runoff is dropping and Denver water plans to adjust the tunnel to meet demand. Flows could go up or down a bit this week with warm weather and minimal precip in the forecast. I think it will be runnable all week.

This weekend looks like it gets hotter and I would expect flows to bump up. More updates on that as the weekend gets closer.

Denver water plans to hold the tunnel steady at 275 cfs today. They think that they will probably keep the tunnel at that flow over the weekend. Flows are fun in the low 300's. Have a great weekend on the north fork if you get out there.

Check out the rough hewn log pedestrian bridge that the bailey fest landowner just finished. Its nice. We will be able to party on one side of the river and camp on the other for bailey fest, effectively doubling our fest party/campground space. Love it!

Denver Water is cutting back the tunnel from 275cfs down 50 cfs to 225 cfs today. Should result in about 270cfs in the river. Flows will fluctuate with demand, which is a function of temps and precip. I'm a little surprised that they are cutting flows and that demand is lower. Looks like a warm week ahead of us, so I am hoping that they turn up the tunnel a bit more.

Denver water is bumping up the tunnel to do a test. They told me 240 but the tunnel us reading 260. Either way, small bump up from 225, but every cfs helps. No word on whether the leave it there or drop back to 225 after the test today.

In the next couple of days the think they will cut cheeseman and bump the tunnel to 275-300 flows.
