This website provides data resources, including spatial datasets and other useful data for water resources.
The datasets listed below are organized and formatted to simplify use.
In many cases datasets consist of reformatted or value-added data from an original data source.
OWF does not generally collect data, although we may help access hard-to-find data and join separate datasets.

Data files should generally be downloaded because the URLs to data may change.
