In a recent PBS piece, our Sun Corridor Program Director talks about Sonoran's involvement in the project's development. He goes on to discuss the Environmental Impact Statement process and the critical concept of integrated infrastructure. As always, it is vitally important that stakeholders work together from start to finish.

EPA Clean Power Plan

The Sonoran Institute prepares a statement on today's release of the U.S. EPA's Clean Power Rules in order to discuss the platform for our study to be released next month. We will reveal how large-scale solar can do far more in meeting the EPA's emissions targets than originally envisioned in the rule.

Colorado River Delta Water Trust

The Colorado River Delta Water Trust is Mexico’s first water trust dedicated to acquiring and leasing water for environmental purposes. The Water Trust, formed in 2008 by a partnership of NGOs including the Sonoran Institute, Pronatura Noroeste, and the Environmental Defense Fund (EDF), serves as a critical mechanism through which water can be secured and dedicated to the Delta in perpetuity.

To learn more about how the Colorado River Delta Water Trust works, read our report.

In November 2012, a landmark agreement known as Minute 319 was made between the United States and Mexico that defines how the two countries will share Colorado River water amidst growing pressures on water resources. The agreement includes an environmental component to bring water back to the Colorado River in Mexico and expand restoration efforts in the Delta.

As part of the agreement, the Colorado River Delta Water Trust is required to secure one-third of the total flows that will be allocated to the Colorado River, while Mexico and the U.S. will contribute the remaining two-thirds of the flows. Additionally, the agreement requires the NGO coalition to scale-up restoration efforts in the Delta.

The Delta Water Trust coalition is partnering with the Nature Conservancy, National Fish and Wildlife Foundation, and the Redford Center in a fundraising campaign, Raise the River, to secure water and accelerate on-the-ground restoration efforts. Raise the River aims to raise $10 million by 2017 to fulfill the Trust’s commitment per the agreement. The goals of Raise the River are to secure a base flow for the river, temporarily reconnect the Colorado River with the sea, and enhance 2,300 acres of habitat by 2017. By accomplishing these goals, the campaign hopes to establish a framework for the long-term dedication of water to the Colorado River Delta.
