Rio Grande Water Deliveries
The State Department announced an agreement with Mexico to provide more reliable and predictable water deliveries to the Rio Grande, a river they share. These deliveries are required under a 1944 treaty, but Mexico fell behind in the previous five-year delivery period.

In a press release, the State Department said that Mexico agreed to deliver a minimum of 350,000 acre-feet per year in this five-year cycle. That is the average amount required annually under the treaty.

According to the release, Mexico also agreed to a “detailed plan” to repay its deficit from the previous cycle.

A State Department spokesperson declined Circle of Blue’s request for more specifics on the plan.

Line 5
The Army Corps of Engineers published the final environmental review of a proposed 3.9-mile tunnel for a controversial oil pipeline.

The pipeline is called Line 5, which runs 645 miles across the Great Lakes region. Line 5 sits on the lakebed at the Straits of Mackinac, where Enbridge, the Canadian company that owns the pipeline, wants to bore a tunnel to house its replacement, which would be less exposed to strikes from boat anchors. Michigan’s Democratic leadership has attempted to shut down the pipeline.

The Army Corps review focused on impacts from tunnel construction, spoils disposal, and decommissioning the existing dual pipelines. It did not consider climate impacts.

Critical Minerals
The House passed the Critical Minerals Dominance Act, a bill that codifies parts of President Trump’s executive orders to speed up mining approvals on federally managed public lands.

The bill authorizes mapping of mineral deposits, identifying and approving priority projects, and an assessment of regulations that impede mining.

Colorado River Water Supply Forecast
The Colorado River water forecast, which already was abysmal, worsened significantly since the beginning of the year.

Total snow cover in the river’s upper basin, which provides most of its water, is the lowest in at least the last 25 years, according to the February outlook from the Colorado Basin River Forecast Center, a division of NOAA. Snow-water equivalent, a measure of water held as snow, is 47 percent of average in the watersheds above Lake Powell, also a record low.

Meager snow is due in part to a dry January. Precipitation was between 50 and 75 percent of the 30-year average for the month. But it’s also attributable to a warm winter – record heat across the basin in December – in which moisture arrived as rain inside of snow. A wet October, which stoked hopes, has given way to a dry winter.

This translates into a dreadful outlook for Lake Powell. The runoff forecast for the key April-July period is just 38 percent of average, a decrease of 21 percentage points from the beginning of January. This is the midpoint forecast in a range of possible futures.

The terrible hydrology adds pressure on the basin’s leaders as they negotiate difficult water cuts.

Colorado River Deadline
Two months ago, the Interior Department gave the seven Colorado River basin states a February 14 deadline to agree on how to cut their water use from the shrinking river. The deadline is widely expected to be missed.

A gathering of governors in D.C. at the end of January did not result in any breakthroughs. Still, the parties will continue to negotiate. Both the upper and lower basins want the other to sacrifice more.

EPA Extends Coal Ash Deadlines
The EPA extended the deadline for power companies to install groundwater monitoring systems at coal ash waste pits that are no longer in operation. These pits leak toxic heavy metals found in coal waste.

The agency pushed back the deadline, established during the Biden era, from May 2028 to February 2031.

Initial annual monitoring reports are now due by January 31, 2032, a year later than the original rule.

New Mexico Natural Gas Pipeline
The Federal Energy Regulatory Commission is starting an environmental review of the proposed Forza project, a 36-mile natural gas pipeline from Lea County, New Mexico, to Winkler County, Texas.
