Colorado Is Now Out of Drought, But New Mexico Is Not

Click to embiggen.
This graphic displays moisture changes in Colorado over the last 90 days. As you can see, the Eastern Slope and High Plains have been wet. Nearly 11 inches (28 cm) have fallen at my house, and other places have more. While in some climates that counts as "somewhat damp," for us it is "Oh my gawd when will it stop?"

 The plains in particular have had tons of hail, which threaten the wheat harvest.

"Heavy rains and severe thunderstorms continue in the Southern Plains where producers are watching forquality impacts. In Colorado, Wyoming and South Dakota, producers are hoping for dryer and/or warmer weather ahead of harvest." (US Wheat Associates harvest report, July 7, 2023).

On the other hand, it is starting to look like a good summer wildlflower season, although spring was not so good.


A quarter of New Mexico is "abnormally dry," while the southeastern quadrant is in either "moderate" or "severe" drought.

If you find this information endlessly fascinating, visit the .gov "Drought Portal." Your tax dollars at work.

Colorado Drought Map July 5, 2022


Right now I call this good news, getting upgraded to "abnormally dry." And there was more good rain the evening of the 6th as well.

Blog Stew: Who Has Enough Water to Cook It?

 

 


 • A new drought map.
January-March 2022 precipitation hit some record lows. I am relieved to be living in one of the green areas on the map.

 • If you grow up in a city grid, your navigational skills are not so good, says Science.

 • Navajo law enforcement jammed up by the "lure of outdoor recreation":

More people are visiting tribal lands throughout the West and adjacent public lands to hike, bike or boat, and they’re accompanied by concerns about trespassing and vandalism at cultural sites, as well as traffic accidents and other issues.

The Wisdom of the Hackberry: Reflections on a Weird Gardening Year

One day this past week our little hackberry tree turned golden. It was alone in that—true, the aspens are turning at higher elevations, but here the lanceleaf cottonwoods, the Gambel oaks, the various berry bushes, are  all still green. 

We got it a few years ago at some nursery in Taos, possibly the now-closed Blossoms in Ranchos de Taos, or possibly Petree, but I think it was Blossoms.

I nearly lost it one year to drought, but it has come back up to where — although the picture does not suggest great height — it is a couple of feet taller than I am. Hackberry is supposed to be fast-growing. That is true in the good years.

"Hackberry," says the University of Nebraska Extension Service, "Celtis occidentalis, is a native tree to the region. It grows up to 60 feet tall and has a spread of 50 feet. It is in the same family as the elm tree, Ulmaceae."

Another site notes that hackberry "can withstand high salt, acid, sand, clay and alkali levels in soils, as well as survive extended flooding and drought." 

"Flooding and drought" summarizes the 2021 growing season. Spring and early summer were soaking. In an article celebrating this year's hay harvest, one of the county weeklies said the core growing area received more than 19 inches (4.75 hands for the horsey set, about one cubit for you Mesopotamians) of rain in the spring in summer. At my place, I saw water running downhill in places where I had never seen water before, not even when big spring snow dumps melted.

"Ah," I thought, "this will recharge the soil moisture, and we will have wildflowers and vegetables and mushrooms and all of it."

Not so fast, hopeful foothills gardener!  

Our "Holderness" (that's its name) clay soil holds water if you apply it slowly, which nature often does not. As my old Soil Conservation Service book on local soils says, 

Holderness "loess and residium that derive from sandstone . . . . the native vegetation is mostly foothills grasses. . . . . Permeability is slow, and the available water capacity is high. . . . runoff is moderate or rapid, and the hazard of erosion is high. Gully erosion is common. This soil is suited to pasture and grazing. (Description updated here.)

M. was at the grocery store two days ago, and someone else was describing her vegetable garden this year as "crappy." I think that happens when you plant late because it's cold and wet — and then the weather goes dry and hotter than average in late summer, making it almost impossible to keep up with watering plants.

As for the local wildflowers, they were not all that spectacular. Maybe they need more recovery time. Up a little higher, about 8,500 feet, I saw amazing flowers in an area that burned in 2016, however, with aspen saplings coming up everywhere.

Mushrooms down here were not. The usual Agaricus campestris never popped (well, there was one I left alone) and the normal Suellus "slippery jacks" never appeared. 

But up in our usual mushroom grounds, the harvest was spectacular, so no complaints.

Instead, this was the Year of Tall Grass. To come up our driveway is to experience driving between banks of grass like grain waiting for the scythe — I say scythe because I mean tall stuff, not like dwarf wheat bred for combine-harvesting.

I let much of the cabin lawn go unmowed (the deer bed down in that high stuff, feeling hidden). It was a tough choice—tall grass is more of a fire hazard, but I wanted all those seeds! It sure beats buying seed, and now the mower can spread them. 

Everywhere, grass thicker than I have ever seen. What Holderness wants, it gets.  It wanted the early summer lambsquarter and amaranth; it did not want beets, and it was sort of indifferent to tomatoes, which are bearing but not heavily.

Meanwhile, the hackberry, in its weather wisdom, is one of the last trees to leaf out in the spring, and now it is the first one to cash in its chips when autumn comes. It knows that abrupt changes from cold to hot and back again are commonplace and always have been, as long as there have been hackberries. As the saying goes, "normal is just a number."

Not-Gardening in a Time of Drought

Lamb's quarter, self-seeded in a big tub.
It rained three nights ago, boosting our total for the past four weeks to a magnificent 0.2 inches, or about 5 mm. Coming after a dry spring, it's serious drought time.

The creek had already gone dry, although the sandy bottom was moist. Since our well is in the creek aquifer—somewhere—the state of the creek is always a concern.

Some areas upstream got more rain than here, and a trickle of flowing water has returned, muddy water that must be coming off an upstream burn scar.

Knowing these conditions were coming, thanks to the shamanic prophecies of the National Weather Service, we did not even try to garden like normal. Almost everything we planted is in containers—some tomatoes, some herbs.

And there there is the Zen of not-gardening.  Instead, we took what showed up on its own.

One is lamb's quarter a/k/a goosefoot, a Chenopodium, which means "goose foot" in Latin. How lambs get into the story, I do not know. I assume that sheep would eat it. When it's too dry even for Swiss chard, these are our greens.

Another edible volunteer is wild amaranth, when it's young. Call them both quelites, if you prefer.

A third is nettles, which M. planted several years ago and which have firmly established themselves, putting them in the class of feral greens. Lots of hippie/Greek nettle pie is eaten in this house, "hippie" because she insists on making a whole-wheat sort of-phyllo dough.

We were going to try growing a similar plant to lamb's quarter, "Good King Henry," Blitum bonus-henricus, this year, but put it off. (In case you were wondering, it was apparently named after Henri IV of France, which just goes to show that you can preside over decades of religious wars and still have a tasty pot herb named for you. He did apparently encourage tree-planting.)

In the woods, brush, and pastures, not much is happening. A few tiny acorns. A scant handful of wildflowers—and what does bloom seems to come early and is stunted, as though the plants are trying to get through an abbreviated life cycle. Even my bomb-proof penstemon is just hanging on, barely existing.

A couple of days ago I thought I saw some Liatris about to bloom, which rocked me back, because its normally a flower that marks the end of summer. I need to go back and double-check. Maybe the plants just want this summer to be over.

Remember the Dust Bowl?


You probably don't remember it, unless you are over ninety. But see the right-hand blob of the red area? That's pretty much the center of the "Dirty Thirties." Compare it to this map.

Drought Monitor, April 28, 2016

Here is the drought picture as of yesterday, which does not show the current storm in eastern Colorado and along the Eastern Slope of the southern Rockies. Wet snow has been falling at my house in the morning of the 28th and is now beginning to stick, eight to ten inches so far, as the temperature hangs just above the freezing point.

Cannabis and Water Law: A Western Reportorial Twofer

Despite the huge importance of water issues in Colorado — headwaters of four or five major rivers (depending how you count) and home of more water lawyers than anyplace — news outlets often don't cover water issues well.

On my first reporting job, at the now-vanished Colorado Springs Sun, it seemed like my colleagues found water issues to be arcane and scary. "Water is hard," to paraphrase Teen Talk Barbie

On my second reporting job, I sat out to educate myself — with not a little help from the late Charles "Tommy" Thompson, long-time general manager of the Southeastern Colorado Water Conservancy District — or as I liked to think of it, the secret government.

The concepts of Colorado water law are fairly simple, but their permutations are endless, and the system operates like warring tribes — if you don't fight, you lose.

But add cannabis culture, and suddenly water issues are not just vital, they are sexy!

"Water District Votes Dry on Pot" (mostly paywalled)

"[Pueblo West] water available for pot growers; St. Charles Mesa keeping moratorium"

"Pot Shop Battles for Water Supply

But this is all the legal stuff. Drought-stricken California sees legal, semi-legal, and outlaw grows using up water and polluting streams:

"Study Finds Medical Pot Farms Draining Streams Dry"

In the Dust Bowl of 2014

There is nothing to see in eastern Colorado. It's all flat and treeless.
 Almost a month ago — January 18th — I took County Road 11 south from Manzanola, Colo., toward part of the Comanche National Grassland. I had driven nine or ten miles when something struck me — I had seen only one small herd of cattle, maybe six head, no more. The rest had all gone to the sale barn, apparently.

I was right about where the red arrow is pointing in the graphic from the United States Drought Monitor, and what was in theory a quail-hunting trip was, admit it or not, turning more into disaster tourism.

Outdoor writer Chad Love blogs from a location downwind of that location, and he has posted some photos that, once converted from color into black-and-white, evoke the Dirty Thirties.

I didn't photograph those six cows, nor the herd I saw somewhere on Colorado  Hwy. 10 grazing in the slanting sunset light in a pasture that was about half dirt, even though it would have been nice and National Geographic-y. Like something from East Africa.

Windmill on the national grasslands. Not pumping.
Fisher the dog and I took a walk around this windmill. There was no water in the tank, no bird tracks of any sort in the dust.

We drove on to another spot closer to the Purgatory River where there was a little water, but all we saw was a single mule deer slipping away. Very quiet. Very dry. Just a general sense of absence.

Chasing scaled quail involves a lot of a windshield time—and to be honest, I have done better in more agricultural areas, but this trip was degenerating into disaster tourism.

So I admitted that I was doing that, ate a late lunch of crackers and coffee, and drove around.

We drove past the Huerfano River Wind Farm outside Walsenburg—as usual for wind farms, not all the blades were turning—and Fisher got a piss break at Huerfano Butte.

And there is the mystery of those deserted commercial buildings on the gravel road in totally misnamed Apache City.

It was good to be back into the mountains and seeing snow.

Reading Water Flows with Trees

Via Coyote Gulch, I learned about TreeFlow, a project to reconstruct centuries' worth of river flows in the West through correlating them with tree rings. "A tree-ring reconstruction is a best-estimate of past streamflows, based on the relationship between tree-ring data and observed streamflow over the modern period."

Here, for example, is the reconstruction of the Colorado River's flow at Lees Ferry, Arizona, going back to 750 CE (scroll down for that graph).

Closer to home, the Arkansas River at Cañon City, Colorado, from 1685–1987.

The process correlates tree rings with observed data from the late 19th century to the present, then projects the correlation back over older tree ring samples from cores or archaeological sites. More about the process here.
The persistent drought conditions that emerged across the West in 1999, especially the extreme drought year of 2002, indicated that the observed records of streamflow in the region did not capture the full range of natural hydrologic variability. This drought, along with increasing demands on water supplies led to a need to assess the range of drought conditions that were likely to occur. Tree-ring reconstructions of streamflow, extending several hundred years or longer, provide a more complete representation of past variability. Accordingly, streamflow reconstructions attracted more interest within the water management community as a potentially useful tool for planning.

Drought Conditions Improve in Colorado, New Mexico



The strong monsoon season has helped ease the drought. I see that our area has dropped from "severe drought" to "abnormally dry." 

The creek near our house faltered in mid-summer but recovered before going completely dry. A rancher neighbor says that he has been able to irrigate for a few days, although I am sure that he would rather have had that water in June.

Denver Post photo
In northern Colorado, there is no drought at all! That happens when you get a year's worth of precipitation in a few days.

In fact, in some areas, soil moisture has been recharged the old-fashioned way.

Then there is the oil-spill problem.

What Kind of Water Year Was It?

Hydrologists measure "water years" from October through August, so this diagram shows the year that just ended.
