Science and Technology Program Western Water and Power Solution Bulletins
What is a Bulletin?
A Reclamation Science & Technology Program Western Water and Power Solution Bulletin is a brief news release for Reclamation end-users, stakeholders, and other parties interested in S&T Program findings. A Western Water and Power Solution Bulletin can consist of a valuable synthesis of available information in a particular research area or a summary of a research product that will assist Reclamation in carrying out its core mission of water and power delivery. A Bulletin summarizes new findings, tools, applications, and capabilities and explains how these findings or products can and will be employed in carrying out Reclamation’s mission. A Bulletin will also provide key contact information for the principal research investigator, the S&T Program Office, and the link for more information or a completed report.
We are in the process of developing more bulletins and will post these bulletins on a searchable knowledge base in the future. Let us know what you think of these first bulletins.
