Cottonwood Creek stays impaired with no cleanup plan on file
August 9, 2026
Cottonwood Creek, threading through this stretch of Shale Deserts and Sedimentary Basins country, has been sitting on the EPA's impaired waters list without the cleanup plan regulators are supposed to write for it. That plan, a Total Maximum Daily Load, is meant to function as a pollutant budget: a ceiling on what can be discharged, and by whom, before the stream is considered back in compliance. Cottonwood Creek has none. The record doesn't specify which pollutant triggered the listing in the first place, which limits how much can be said about the underlying mechanism, but the practical effect is clear enough: there's no binding target steering recovery, just an open listing with nothing attached to it.The contrast with nearby Short Draw is instructive. It's also listed as impaired, but it already has a completed TMDL on file, meaning whatever problem it's addressing is at least moving toward a fix. Cottonwood Creek has no such marker of progress.Of the 19 facilities holding active discharge permits within ten miles, ten have racked up violations in the past four quarters, and one enforcement action has been taken, carrying $14,400 in penalties. None of those facilities has been tied specifically to Cottonwood Creek's impairment, and none currently rises to the EPA's most serious noncompliance tier. That's a mild sign, not a clean one; it means the known violators aren't the obvious culprits, not that the creek's problem has been ruled out or explained.This is a landscape already defined by extremes in water: monsoon pulses that can flood a dry wash in minutes, followed by irrigation draws that pull streams down to a trickle. An impairment listing without a cleanup plan is easy to lose track of in that kind of setting, precisely because it doesn't announce itself. There's no fish kill, no visible plume, just a bureaucratic gap that persists quietly while the water keeps moving through it.
River drops to a trickle as irrigation season peaks
July 11, 2026
The river has fallen to a trickle — just 0.7 cubic feet per second today, down from nearly 270 cubic feet per second two weeks ago when snowmelt was at its height. Senior water rights are drawing the channel onto irrigated orchards upstream, leaving the stream channel nearly dry at peak irrigation season.What used to be a seasonal drought is becoming a pattern. Earlier springs mean snowmelt now peaks and depletes faster with each passing decade, leaving these hot, dry weeks longer and more intense. The stream temperature sits at 13.3°C, but as flow dwindles and air temperature climbs through July, the water will warm further — stressing the aquatic life that depends on this connectivity.The margin between ecological function and collapse narrows each time the cycle repeats. Fish, amphibians, and invertebrates that time their life cycles to historical flow patterns now face bottlenecks they didn't evolve to survive. The river is still running, but not running as itself.
Monarchs find thistle in midsummer
June 13, 2026
The air shimmers with heat across the sage flats near Paonia, where summer reaches its full intensity. Magpies call from scattered cottonwoods, and the scent of big sagebrush carries on what little breeze moves through the valley. If you are walking here, the sun presses against your shoulders with the weight of the longest days.A monarch butterfly moves through this landscape with purpose that seems impossible for something so fragile. Its orange wings catch the light as it searches, pausing at flower after flower, testing each one. The monarch is looking for something specific in this sea of blooms. Rocky Mountain thistle grows here in scattered patches, its purple flower heads rising above spiny stems. Both the butterfly and the plant share something beyond this moment: they are both threatened species, each rare in a landscape that once held many more of their kind.The thistle offers what the monarch needs most during breeding season. Its deep purple flowers produce nectar rich in the sugars that fuel long-distance flight and egg production. The monarch's proboscis unfurls to reach deep into the flower head, where dozens of tiny florets cluster together. Each floret holds its own small reservoir of nectar, and the butterfly works methodically from one to the next. While feeding, pollen grains stick to the monarch's legs and body, and when it moves to the next thistle, it carries genetic material between plants that may be separated by hundreds of yards.This exchange sustains both species through their most demanding season. The monarch female must find milkweed plants for egg-laying, but she also needs energy-rich nectar sources like thistle to fuel her search and support egg development. The Rocky Mountain thistle depends on pollinators like monarchs to move pollen between its scattered populations. In this fragmented landscape, where invasive cheatgrass and purple crownvetch compete for space, both species rely on finding each other across greater and greater distances. The thistle blooms through midsummer, timing its peak flowering with the monarch's breeding season, when the butterfly's need for nectar is highest.The monarch lifts from the thistle and continues its search, orange wings steady against the afternoon heat. Somewhere in the distance, a western kingbird calls from a fence post, and the sagebrush releases its sharp perfume into air that tastes of dust and summer. The thistle remains, purple against the pale earth, its flowers still heavy with nectar that catches the slanted light.
