#Runoff news (May 26, 2021): #YampaRiver stream flows see possible peak — Steamboat Pilot & Today #GreenRiver #ColoradoRiver #COriver

From the Steamboat Pilot & Today (Dylan Anderson):

There are two spots on Mount Werner that Erin Light looks at each spring to get a rough estimate about when the Yampa River may see peak stream flow.

“A lot of times, it is very close. When those two spots come together, it is probably within a day or two that it will peak,” said Light, the regional division engineer for the Colorado Division of Water Resources. “Looking at the Steamboat (stream flow) gauge, I would say we are probably done.”

Stream flows for the Elk and Yampa rivers likely have already peaked, Light said, pointing to high flow marks Friday and Sunday. It is possible this isn’t the peak, as a spring storm could bolster water levels, but Light said it seems unlikely that is the case this year…

…ranchers in the county are preparing for the worst, irrigating earlier than normal and contemplating taking measures like bringing livestock water in tanks and even selling off part of their herd, because they don’t have enough pasture land with water flowing through it to raise them all…

There is more water flowing out of Stagecoach right now than going in, which happens every year but rarely this early. There are already calls on various ditches in the Yampa Valley, and Light said she expects more.

Light is relatively confident there will be a call on the Elk River, which has happened almost every year since 2012. As for the Yampa, it could be different, as the Colorado River District has a $50,000 grant for strategic releases to hopefully avoid a call on the river. Without that, a call would almost be certain, Light said…

The upper basin is particularly tough right now, said Hagenbuch, who is the director and agricultural agent for the Routt County CSU Extension Office. He said he hopes return flows from irrigation will boost water levels in the coming weeks, but he doesn’t have an optimistic outlook…

[Kelly] Romero-Heaney said there is enough water to support municipal customers in town, but the more they use, the less there is in Fish Creek, which is an important spawning stream for mountain whitefish. She said she hopes Steamboat residents minimize outdoor watering to take some pressure off the resource.
