Several tributaries of the Colorado River get their start in the crags of the Central Colorado mountains. Storied rivers: Blue, Eagle, Roaring Fork and the powerhouse Gunnison. They’ve all faced the footstep of humankind. The mines dotting the slopes, hay fields, ranching, orchards and cornfields bear witness and are now part of the allure of the high country. Folks cast a line, shoot rapids and enjoy the scenery of those waterways.
On September 27, 2017, the International Boundary and Water Commission, United States and Mexico inked Minute 323, the amendment to the 1944 United States-Mexico Treaty for Utilization of Water covering operations on the Colorado, Rio Grande and Tijuana rivers. (The Rio Grande is another of Central Colorado’s contributions to the Western U.S. economy.)
An important part of Minute 323 are environmental flows for the Colorado River Delta. Most everyone knows the river doesn’t reach the sea any longer. Environmental streamflow was initiated under Minute 319 signed by then Secretary of Interior Ken Salazar.
In March 2016 a diverse group of conservationists, biologists, irrigators and government officials effected a release of 100,000 acre-feet of water from Morelos Dam into the dry Colorado River Delta. There was a line of vehicles racing point to point along the river to witness the river’s front. At San Luis Rio Colorado, most of the residents went down to the river to celebrate the return of the river although many had no memory of running water in the sandy channel.
There was a great deal of success from channeling some of the streamflow to restoration sites in the Delta. Within weeks, new growth sprouted – cottonwoods and willows. Much of the diverted water served to replenish groundwater supplies. Wildlife immediately started using the habitat.
There probably won’t be a repeat of the Colorado River once again reaching the sea. The environmental flows in Minute 323 are planned to be set to work in the restoration of the Delta. It was great to see the river reach the sea but the conservationists want to concentrate flows like irrigators do for maximum yield.
Another feature of the deal allows Mexico to store water in Lake Mead to better manage their diversions for agriculture. The U.S. is also helping to rebuild and upgrade Mexican infrastructure. Under Minute 319, Mexico was allowed to continue storing water, and that water was used for the pulse flow. The idea is that greater efficiency in Mexico will lead to more storage in Lake Mead.
Currently, Arizona, California and Nevada are working on a drought contingency plan to stave off a shortage declaration in Lake Mead. Arizona’s Colorado River allocation takes a big hit under a declaration. Mexico’s water in Lake Mead will help. Negotiations about the drought contingency plan will now move forward with greater certainty with the signing of Minute 323.
The final signatures for the Minute came from Roberto Salmón (Mexico) and Edward Drusina (U.S.). There were several officials from President Obama’s administration in attendance, including Jennifer Gimbel and Mike O’Connor. The negotiations started before last year’s election but did not conclude before the inauguration.
Minute 323 is an important piece of the puzzle for administering the Colorado River.
Central Colorado is joined at the economic hip with the Colorado River. A lot of transbasin water flows down the Arkansas River from the Twin Lakes and Fryingpan-Arkansas projects. Some is pumped over to South Park by Colorado Springs and Aurora but most of it goes down to Lake Pueblo and the Fry-Ark partners. Colorado Springs, Fountain and Security pump some back north in the Fountain Valley. Cities along the river divert and treat the water for their populations. The water also is used to grow the famous crops in the Arkansas Valley: Rocky Ford melons, Pueblo chile, corn and others. Timing the releases from Twin Lakes and Turquoise Reservoir also contributes to the rafting economy. 100 miles of the Arkansas River are designated as gold medal fisheries. Transbasin flows help the riparian habitat.
• Comments about managing the Arkansas Headwaters Recreation Area are due by November 10, 2017. Check out the AHRA Plan Revision page on the Colorado Parks & Wildlife website.
• Congratulations to Wet Mountain Valley ranchers Randy and Claricy Rusk for winning the Dodge Award for a lifetime of conservation from the Palmer Land Trust.
• Congratulations to the Colorado Parks & Wildlife folks at the Roaring Judy Hatchery for successfully spawning the line of Cutthroat trout rescued from Hayden Creek during the Hayden Pass Fire.
• James Eklund has moved on from the Colorado Water Conservation Board and Becky Mitchell is the new director.
• Coloradans cam now legally collect rain off their roofs. Governor John Hickenlooper signed House Bill 1005 in May.
• R.I.P. Gary Bostrom. He was one of the driving forces behind Colorado Springs’ $825 million Southern Delivery System.
