The Colorado River Science Wiki is a web-based clearinghouse for scientific and technical information relevant to the Colorado River Basin and the management of its water resources and related natural resources. This clearinghouse is intended to be useful to managers and other decision-makers, to researchers, to the media, and to the broader public. Its objectives are to:

  • Share recent and ongoing Colorado River research efforts and findings
  • Provide up-to-date synthesis of the science relevant to management
  • Allow one-stop access to key technical datasets and data tools
  • Provide guidance for the ongoing Interim Guidelines renegotiation
  • Engage the greater Colorado River community in a joint information-gathering effort

As of May 2022, the Wiki is still in the early stages of development. We welcome your comments and questions; please see the contact information at the bottom of this page.


There are 6 sections in the Wiki. Each section can be accessed via the navigation panel on the left side of the page.

1) Science and applications

Provides up-to-date information across dozens of areas of management-relevant science. Each page contains at least the following:

  • Summary description of the topic
  • The topic's relevance to Colorado River water management
  • Annotated links to datasets, tools, and other information and science synthesis on that topic

2) Data and tools

Collates all of the annotated links to the datasets and tools from Section 1, to make them available in one place.

3) New research

Lists and new research studies and relevant reports published since 2020.

4) Water law and policy

Describes the legal and policy context in which the science and applications to inform water management are implemented.

5) Who's who

Identifies key players in the science-to-applications (aka research-to-operations, or R2O) chain in the basin, and provides links to homepages and other resources.

6) Introduction to the Basin

Intended mainly for users who are not familiar with the Colorado River Basin.


The initial development of the Wiki is being carried out by Brad Udall (Colorado Water Center, Colorado State University), Julie Vano (Aspen Global Change Institute), and Jeff Lukas (Lukas Climate Research and Consulting).
