The goal of the GreyJay Project is to provide a single repository for access to useful resources for Canadian hydrologists and water resource professionals. Present here are links to data and tools for hydrologic data analysis, data manipulation, and visualization for hydrologists working in Canada and elsewhere.


If you are interested in contributing to the GreyJay project or keeping up to date, please e-mail us and indicate that you wish to be on the mailing list. This site houses the main sites for two major initatives:

  • the Canadian hydRology Project works towards the development of a specialized package in R for use by hydrologists in Canada and elsewhere.
  • the GreyJay Model Hub is a set of repositories for hydrologic modelling software, complete with SVN and trac support for model development and versioning.
