New research
This section of the wiki highlights new research--peer-reviewed papers, book chapters, agency reports, and other documents--relevant to the management of water and related resources in the Colorado River Basin, as identified by Wiki administrators and contributors.
All such research will have the basic bibliographic information provided, with links to the online document, annotated with a ($) if it is behind a paywall.
Research that seems especially noteworthy and/or useful to basin stakeholders will also have a (mostly) plain-language summary of 500 words or less.
