Project Data

Dam project data are often received both as hourly measurements, as well as daily totals or averages. Each are useful, depending on the time frame of interest.

Hourly project data are reported for 7 to 14 days in the past.

Daily project data are reported in week- and month-long reports.

Certain project data are also available as water-year reports, or yearly project data (below).
