⛈️ Wacky Weather Watch⚡️

Tropical disturbances have moved into the Four Corners Country in recent days, bringing massive amounts of moisture, raising river levels, and causing flash flooding. The pattern — and high danger of flooding — is expected to continue this week [September 21, 2026], with the highest rainfall forecast for New Mexico. 

Snow-nerd Andy Gleason reported that, as of Sept. 18, 3.5 inches of rain had already fallen in Silverton during the storm cycle. The National Weather Service also says the percentage of water in the atmosphere, or PWAT, in the area was 300% of normal, higher than they have ever recorded before.

Streamflows across the region shot up once again, with the San Juan River at Four Corners reaching 13,000 cubic feet per second on Sept. 19. That was enough to send it over its banks in some places in and around Shiprock, and Navajo Nation police evacuated residents near the San Juan Bridge, which high waters threatened.

The high flows sent a surge of water into Lake Powell, causing inflows to exceed releases and bringing the reservoir’s surface level up by a few inches. However it remains below 53,517 feet — or a mere seven feet above the level the Bureau of Reclamation plans to “defend.”

It’s increasingly likely that this series of September storms will bring total accumulated precipitation in Four Corners watersheds up to or above median levels by the 2026 water year’s end on Sept. 30.

Notice how accumulated precipitation in the San Juan River watershed for the 2026 water year, indicated by the black line, was at record levels during its first weeks and didn’t drop below the median until February. The latest round of storms — along with those to come — could push the levels back up to or above the median before the water year ends Sept. 30. Source: USDA.

That may seem surprising given how dry last winter was, how severe the drought is in much of the West, and how low streamflows have been all summer. But big storms in the early part of the water year (last October) and now at the end of it have buoyed accumulated precipitation levels, which exceeded those in water year 2025. The problem this year was one of timing, with most of the moisture coming before snow-season, and of warmth: It is shaping up to be the warmest water year on record across most of the West.

🐟 COLORADO RIVER CHRONICLES 💧
  • Tech giant Amazon plans to invest $20 million into Colorado River Basin water conservation projects as part of the newly formed Colorado River Basin Collaborative. Amazon’s first two funded projects include a leak-detection and repair effort in Orange County, California; and working with Arable on irrigation efficiency efforts on tribal farmland in Arizona. (Amazon News)
🐓 REGULATORY CAPTURE RECORD 🦊
  • Idaho investigators find that a 5,600-acre wildfire in 2024 was initially ignited on Trump appointee Michael Boren’s ranch by Boren’s brother, Steve, who did so without a permit. The fire cost approximately $950,000 to contain. (Public Domain / High Country News)
🌵 PUBLIC LANDS 🌲
  • U.S. Sen. Mike Lee (MAGA-Utah) moves to use the Congressional Review Act to revoke the Bears Ears National Monument management plan and block the development of a substantially similar plan in the future. While this would not prevent a future administration from restoring the original national monument boundaries, it would hamper efforts to to create a new management plan for a restored monument and could throw the entire area — even BLM lands removed from the monument — into a sort of regulatory chaos. (news release, Wes Siler’s Newsletter)
  • The U.S. Forest Service considers turning over management of the Maroon Bells Scenic Area near Aspen, Colorado, to Pitkin County, saying it can no longer sustain the $300,000 annual loss at the site. The USFS plans to use a categorical exclusion to skirt the environmental review process, raising concerns about setting a dangerous precedent that would allow similar public lands transfers without analysis. (Westwise)
  • The Trump administration’s ongoing dismantling of the National Park Service continues, as it funnels funds intended for repairs and maintenance in popular Western parks to President Donald Trump’s vanity projects in Washington, D.C.. (New York Times)

SACRED LANDS
  • The Navajo Nation council formally recognizes as a sacred site Tooh Ahidiilíní — the confluence of the Little Colorado River and the Colorado River, the Little Colorado River Gorge, and surrounding areas. The legislation provides additional protection against development such as the now defunct Escalade project or once-proposed pumped hydropower storage projects. (Grand Canyon Trust)
⛏️ Mining Monitor ⛏️
  • The Navajo Nation Environmental Protection Agency pushes back on NuFuels’ proposed Crownpoint Uranium Project in-situ-recovery facility, per the Diné Natural Resources Protection Act of 2005, which bans uranium mining and processing on the Navajo Nation. The facility would be located near the site of the 1979 Church Rock uranium tailings spill, the largest release of radioactive materials in U.S. history. (Navajo Times)
  • Laramide Resources said it is moving ahead with its proposed La Jara Mesa uranium mining project on the Cibola National Forest west of Mt. Taylor in New Mexico, despite intense opposition and a federal permitting pause. (Santa Fe New Mexican)
🛢️ FOSSIL FUEL FOLLIES 📈
  • The Bureau of Land Management considers opening the Ouray National Wildlife Refuge near Vernal, Utah, to oil and gas leasing. If developed, the leases would come with “no surface occupancy” stipulations, meaning directional drilling would occur outside the refuge to reach the federal minerals underneath it. (news release, Times-Independent)
  • U.S. Sens. John Hickenlooper and Michael Bennet (D-Colo.) join the Southern Ute Indian Tribe in opposition to the Bureau of Land Management’s plan to auction oil and gas leases within the tribe’s reservation in southwestern Colorado, saying they are in an “environmentally and culturally significant” area. (news release)
  • Today (9/21) is the last day to submit comments to the Bureau of Land Management on 43 proposed oil and gas leases on almost 75,000 acres in Utah, including parcels near Hatch Point just outside the pre-shrinkage boundaries of Bears Ears National Monument. (BLM, SUWA)
  • The Bureau of Land Management receives no bids for offered oil and gas leases covering 20,600 acres in Nevada, triggering a replacement sale and making the parcels available for noncompetitive bidding. (Taxpayers for Common Sense)

🤖 DATA CENTER DIGEST 👾

  • The Hualapai Tribal Council in Arizona passes a resolution opposing “the irresponsible development of hyperscale data centers, saying they pose a “direct and severe threat to the tribe’s sacred water, lands, environment, and way of life.” (KJZZ)
  • A new study explores siting data centers on abandoned mine lands and using the acid mine drainage to cool the facilities. (Science Direct)

South Platte River Basin #climate for the week ending September 28, 2026, and the latest Seasonal Outlooks, through December 31, 2026, from the CPC #SouthPlatteRiver

Below is the Precipitation Accumulation in South Platte graph from the NRCS for September 28, 2026. This morning precipitation, at the SNOTEL stations, is at 75% of the median (down 1% one week), and 75% of the water year median (down 1% one week). There are 2 days left in the water year.

Showers are likely today, Tuesday, and Wednesday, with a slight chance for showers Sunday in the central mountains. Showers are likely today and Tuesday, with a chance for showers Wednesday, and a chance for showers Sunday in the northern mountains. Showers are likely today, Tuesday, and Wednesday, with a chance for showers Thursday, down here, about 441 miles from Mesa Verde National Park. From the NPS:

The Far View area was once an extensive farming community and one of the most densely populated regions of the Mesa Verde. This mesa top community includes Far View House, Pipe Shrine House, Coyote Village, Far View Reservoir (currently dry), Megalithic House, and Far View Tower. In ancient times, it was a place of modest homes interspersed with small farm fields. It was a place filled with people, vibrant life, and constant change. 

Beginning around 800 CE, Ancestral Pueblo people lived here for several centuries, farming the deep mesa-top soils, building their homes, and raising their families. This was not always a quiet woodland. On a summer day in 1050 this ancient community would have been filled with the smell of juniper smoke and the sounds of everyday life: conversations between people working together, barking dogs, laughing children, ravens calling overhead, and the wind rustling through the shiny corn leaves. In the mid-1100s, there may have been at least 35 occupied villages and surrounding farm and garden plots within a half-square-mile area, including those you can visit today.
