The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) provides cyberinfrastructure and educational resources to a diverse community of water scientists and practitioners. CUAHSI has grown its programs and services in recent years, but increasing engagement of our audience is an ongoing challenge. CUAHSI recently partnered with the Science Gateways Communities Institute (SGCI) to perform an organizational audience analysis and the Texas Advanced Computing Center’s (TACC) Expanding Pathways in Computing (EPIC) STEM Evaluation Services to perform a user experience evaluation for our data repository, HydroShare http://www.hydroshare.org. This presentation will summarize the outcomes of our analyses and how we have applied these findings to improve our engagement with both our broad audience and HydroShare users. **Resource Use**: *License*: [CC-BY](https://creativecommons.org/licenses/by/4.0/legalcode) *Recommended Citation*: Clark, E.
