This flow data is collected at seven Clark County and three Clark Public Utility sites. The data are organized by watershed and presented by water year. A water year begins October 1 and ends September 30 of the next year. The name of the water year is based on the January through September portion of this time period. For example, WY 2006 is from October 1, 2006 through September 30, 2007.
Data is available as hydrographs, mean daily flows/QTables, and 15-minute flow tables.
Finalized data have been reviewed for accuracy whereas more recent provisional real-time data have not been checked.

Hydrographs: depict how mean (average) daily discharge (flow) varies over time in cubic feet per second utilizing a log scale for flow.
QTables: delimited text files with the mean daily flow values in cubic feet per second and monthly and annual summary statistics
15-minute flow table: Excel spreadsheet with instantaneous flow in cubic feet per second at 15 minute intervals. Please note, these are large files.
