Archival outreach, an essential activity for any repository, should focus on what constituents are already doing and capitalize on existing venues related to the repository's subject area. The Water Resources Archive at Colorado State University successfully undertook this integrative approach to outreach. Detailed in the article are outreach opportunities the Water Resources Archive used, including conferences, learning opportunities, one-on-one meetings, brochures, newsletters, and a Web site. Successful outcomes are also given as part of the case study. (Contains 3 figures and 10 notes.)
