Durango faces a different scenario than many other municipalities that rely on large water reservoirs for their supplies, he said. When a municipality saves a gallon of water, for example, that water stays right there in its reservoir until it is needed. But Durango “lives on the flow” of the Animas and Florida rivers, Biggs said. On one hand, the city isn’t reliant on reservoirs that may be in short supply of water. But on the other, if the rivers are short on supply because there isn’t enough runoff, the city’s only choice is to clamp down on restrictions and wait out the shortage, he said…
The city is looking into installing a pipeline that would connect Lake Nighthorse to the College Mesa water-treatment facility, Mayor Kim Baxter said, which would allow Durango to take a more proactive approach to drought management and mitigation.
The Colorado Department of Public Health and Environment’s Water Quality Control Division is proposing the limits for 11 Colorado River tributaries in the valley with impaired water quality because of high levels of dissolved selenium and total recoverable iron, and in the case of two of the tributaries, E. coli. The river itself along that stretch, which meets water quality standards for selenium and E. coli, but not iron, is not itself targeted by the proposal, although it would benefit from it.
As required by the federal Clean Water Act and by Environmental Protection Agency regulations, the state is developing what it calls total maximum daily loads (TMDL) that would establish how much of those pollutants can enter each of the tributaries each day while maintaining water quality standards.
The area being targeted by regulators altogether encompasses about 138 square miles, stretching from Lewis Wash in the Clifton area to Salt Creek in western Mesa County. The area is all north of the Colorado River and is bounded on the northern end by the Government Highline Canal. That location beneath the canal is noteworthy because selenium is naturally occurring in the Mancos shale geological formation in the area, but at high levels in water can be harmful to fish and aquatic birds. The Water Quality Control Division, in its draft Grand Valley TMDL public notice, says that “the predominant source of selenium in all of the watersheds is likely groundwater inflow from canal seepage and deep percolation from irrigated lands.” Put another way, the valley’s irrigated agriculture, lying downgrade of the Government Highline Canal, is mostly driving the selenium problems in the drainages.
But as it happens, state water-quality regulators have little say over that agricultural activity. The Water Quality Control Division holds permitting authority over point sources of surface water discharges. Agricultural stormwater discharges, and return flows from irrigated agriculture, aren’t considered point sources under the Clean Water Act. The state relies on incentive-based approaches to encourage partners to work on voluntary measures to address contaminants, something that grant funding is available to support. This can include measures such as lining or piping canals and changing irrigation methods and schedules to reduce the leaching of selenium…Still, a concern for some people, including Trent Prall, public works director for the city of Grand Junction, is that because of the state’s lack of authority over the agricultural side of things, it will lean on permitted sources of surface water discharges to fix a problem that is largely agriculture-driven.

Precipitation over the past 30 days was well below average for the bulk of the western United States. Central Wyoming, eastern Colorado, and central New Mexico were the anomalies in the west, receiving above-average precipitation. Despite the late start to snow this season, winter precipitation ended up near average for Colorado Springs and Pueblo. This allowed a decrease in drought conditions…
Drought for the western US holds strong. NOAA classifies the current drought to be the “most extensive and intense drought in the 22-year history of the US Drought Monitor.”
Snowmelt this year is expected to be slightly below normal in accordance with the current snowpack, which is 91% of normal statewide as of April 7…Colorado’s luck seems to run out past the state lines. The Colorado River is the lifeline of the southwest US, supplying water to Lake Powell and Lake Mead. These lakes remain at concerning low levels as drought remains relentless.
According to an analysis from the National Weather Service Colorado Basin River Forecast Center, Blue Mesa Reservoir’s current storage is 29%. Flow into the Blue Mesa will be 83% of normal during this year’s run-off. Lake Powell is at 24% storage currently, and spring run-off will flow into Lake Powell at 64% of normal flow.
Democracies are making more progress than autocracies when it comes to climate action. But divestment campaigns can put pressure on the most recalcitrant of political leaders
At first glance, last autumn’s Glasgow climate summit looked a lot like its 25 predecessors. It had:
A conference hall the size of an aircraft carrier stuffed with displays from problematic parties (the Saudis, for example, with a giant pavilion saluting their efforts at promoting a “circular carbon economy agenda”).
Squadrons of delegates rushing constantly to mysterious sessions (“Showcasing achievements of TBTTP and Protected Areas Initiative of GoP”) while actual negotiations took place in a few back rooms.
Earnest protesters with excellent signs (“The wrong Amazon is burning”).
But as I wandered the halls and the streets outside, it struck me again and again that a good deal had changed since the last big climate confab in Paris in 2015 – and not just because carbon levels and the temperature had risen ever higher. The biggest shift was in the political climate. Over those few years the world seemed to have swerved sharply away from democracy and toward autocracy – and in the process dramatically limited our ability to fight the climate crisis. Oligarchs of many kinds had grabbed power and were using it to uphold the status quo; there was a Potemkin quality to the whole gathering, as if everyone was reciting a script that no longer reflected the actual politics of the planet.
Now that we’ve watched Russia launch an oil-fired invasion of Ukraine, it’s a little easier to see this trend in high relief – but Putin is far from the only case…
The cost of energy delivered by the sun has not risen this year, and it will not rise next year…
As a general rule of thumb, those territories with the healthiest, least-captive-to-vested-interest democracies are making the most progress on climate change. Look around the world at Iceland or Costa Rica, around Europe at Finland or Spain, around the US at California or New York. So part of the job for climate campaigners is to work for functioning democratic states, where people’s demands for a working future will be prioritized over vested interest, ideology and personal fiefdoms. But given the time constraints that physics impose – the need for rapid action everywhere – that can’t be the whole strategy. In fact, activists have arguably been a little too focused on politics as a source of change, and paid not quite enough attention to the other power center in our civilization: money. If we could somehow persuade or force the world’s financial giants to change, that would yield quick progress as well. Maybe quicker, since speed is more a hallmark of stock exchanges than parliaments.
And here the news is a little better. Take my country as an example. Political power has come to rest in the reddest, most corrupt parts of America. The senators representing a relative handful of people in sparsely populated western states are able to tie up our political life, and those senators are almost all on the payroll of big oil. But money has collected in the blue parts of the country – Biden-voting counties account for 70% of the country’s economy. That’s one reason some of us have worked so hard on campaigns like fossil fuel divestment – we won big victories with New York’s pension funds and with California’s vast university system, and so were able to put real pressure on big oil. Now we’re doing the same with the huge banks that are the industry’s financial lifeline. We’re well aware that we may never win over Montana or Mississippi, so we better have some solutions that don’t depend on doing so. The same thing’s true globally. We may not be able to advocate in Beijing or Moscow or, increasingly, in Delhi. So, at least for these purposes, it’s useful that the biggest pots of money remain in Manhattan, in London, in Frankfurt, in Tokyo. These are places we still can make some noise.
