River Forecast Site Issues- Don’t Buy It!

Friday 5 pm

It occurs to me that these stage and flow forecasts are displaying a baseline recession curve. That means they show what would happen without any more rain.

This is what happened with the Dolores River and Mancos River when I woke up cranky and got in trouble (again) this morning. If you missed it, we went two days with CBRFC (NOAA’s Colorado Basin River Forecast Center) forecasting no problems with the Dolores River, while the experts (local residents) emailed me with their concerns. I woke up at 3 am this morning, and their forecast peak was over action stage.

Dolores locals (many whitewater rafters who understand all of this better than I) tell me they are concerned that, at a certain level, the river will take back its historic floodplain. It’s called channel avulsion. Water doesn’t like to be engineered; eventually, water wins.

In the railroad days of the late 1800s and early 1900s, they literally moved the Dolores River to protect the tracks and support a new town layout.

Then early  October 1911, a massive Eastern Pacific Hurricane recurved and turned a firehose over what is now our forecast area (sound familiar?). The Dolores River re-occupied (for a while) its former home.

This was the same storm that flooded Durango in 1911, and Pagosa, and everywhere in our forecast area. The Animas blew right through Durango with 25,000 cfs, washing out the bridges at 15th Street—including the Denver & Rio Grande railroad bridge right where the train used to cross —even after they desperately parked coal railcars on it to try to weigh it down (geniuses)…

Sorry, huge rabbit hole.

Whatever I do, I am not going to talk about the Post Halloween Storm. Yes, Moms and Dads, I looked at the Demons away schedule.

Friday Morning Update

10/23/26 Friday  4 am

Yesterday, in one of my posts, I wrote about the historic flood of 2011. I was off by 100 years. Muscle memory is the culprit. I have been typing 2000s for 26 years, so in my mind I meant 1911, but it came out as 2011. I only heard from a couple of people, so I appreciate them bringing it to my attention as much as I appreciate the thousands of people who overlooked it and knew what I meant.

I am tired and a little cranky. I will do my best to stay on track this morning. But come on CDOT. Nothing like dropping the ball during the big game.

“Sorry, our cameras are out so…”

Besides that, the closures tell the story.

From the CBRFC Colorado Basin River Forecast Center. These are all the sites I need to follow up on, especially the red and yellow dots, but not exclusively.

For the last couple of days, I have been hearing from followers in and near Dolores. Like most long-term residents near rivers, streams, and creeks, they have local knowledge and experience dealing with flood threats.

I am not a hydro=guy, not at all. I hear from a few; one, who asked me not to reveal his name, said I was worried too much about flooding. He tried to tell me that saturated soils absorb precipitation better and that I shouldn’t worry about it. OK.

The last couple of months have exposed me to more heavy-rain threats than I have dealt with in the last 18 years. Now look: DOL (Dolores River at Dolores) and DRR (Dolores River at Rico) made the list today. Guess when the peak forecast time is: Now. Of course, why would anyone want any warning?

That’s the equivalent of the NWS in their forecast discussions saying, “Webcams show snow stakes in the San Juans with 15 inches of snow, so we are raising the forecast to 12-14 inches.” Don’t laugh, I have read that kind of stuff before. We call it “nowcasting”: “It’s raining outside, so we’re increasing our chances of rain to 80% today.”

(Stick with me; long-term followers know when I am tired because I stray off topic quickly, I call it going down the rabbit hole, it usually happens when Sus has a bad day or night)

Caffeine kicking in, RANT OVER (mostly).

NWS just issued a flood warning through 8 am…DUH

Animas Downtown: Currently running above Action Stage. Peak forecast: Noon today

Animas Below Pump Station: Currently running above June 2019 high. Peak forecast: Noon today.

San Juan River at Pagosa: Peak Forecast: Now. Pagosa and Wolf Creek are currently inaccessible because roads are closed.

Piedra at Arboles: Currently running above historical highs. Peak forecast: Now

La Plata River at Hesperus: Above flood stage. Peak forecast: Now

Mancos River at Mancos: Above Action Stage. Peak forecast: Now (another one that made the list while we were sleeping).

Animas River at Cedar Hill: Above flood stage. Peak forecast: 4 pm today. This has been on the list all along. 

Animas River at Silverton: Peak forecast now. The forecast peak height is lower than current observations, which are hitting historical levels. This is another location where locals know more than the experts.

Vallecito Creek: Peak Forecast: Now

Los Pinos above Vallecito: Peak forecast 4 hours ago

Thanks for your patience. I am going to regroup. I’ll do a short model update in a moment. Then a more in-depth model update around 1 pm. At the moment, the latest model runs show this next round will be less impactful, but 1 to 3 more inches are possible
