An End-of-Year summary can be computed after a site has been specified, the appropriate data descriptors have been selected, and a year-long span of time is specified. Generating this summary can take some time because it requires retrieving a year of unit flow, unit stage, and daily flow values, then computation of the peaks. The summary will be incomplete if unit stage or daily flow values cannot be found in the database. The summary can not be generated at all if unit flow values are unavailable.

The 'Save' button at the bottom of the summary allows it to be saved to a text file. The 'Print' button prints the summary to standard output. In the future, this button should send the summary to a printer. The 'Export' button exports the computed peaks to a peak editing window.
