Peaks can be retrieved for viewing end editing after a site has been specified and any span of time is specified. Peaks for the default time span of the most recently ended water year might not yet be in the database. The special-purpose option 'All Peaks' in the date format selection is reccommended if all peaks in the database are desired. Retrieving the peaks can take some time.

Date is the date (and optionally time) of the peak. Q is the flow value of the peak. (Peak Stages do not have flow values.) Max appears checked for the maximum peak of each water year. Highest Since is where the year of a past historic peak may appear. Q codes contain metadata about the Q value. Stage is the stage value of the peak. Stage Codes contain metadata about the stage value. Aging is the data aging code. Creator is the user id of the person who created the record and Created is the date and time when the record was created. Modifier is the user id of the person who last modified the record and Modified is the date and time when the record was las modified.

Permission to edit peaks depends on the user's level of access and the data aging codes in the table. The only way the database is changed is by clicking the 'Commit' button. Saving the table as WATSTORE, RDB, or XML does not change the database.

Buttons are available for displaying details about the four kinds of codes displayed (Q, Associated Stage, Peak Stage, and Data Aging.) All possible codes are displayed. When only some codes are in use in the currently displayed data, the codes that do not appear are grayed out in the details.
