Historical dam count data for Prosser and Roza Dams have now been loaded to the
University of Washington Data Access in Real-Time (DART)
system. Historical daily counts for Roza Dam for the years 1940-1967 and 1982-1985
were obtained and loaded from data provided courtesy of the U.S. Bureau of Reclamation’s
Yakima office. In years where daily counts are not available, the Yakama Nation
has provided weekly counts with data assigned to an arbitrary day in the week
for which counts are available. This is the case for Prosser Dam for the years
1984 to 1991 and for Roza Dam for the years 1986 to 1990.
Daily or weekly count data are now available on DART for Roza Dam for the years
1940 to 1967 and 1982-present and for Prosser Dam for the years 1983 to present.
As you use and review these data, please let us know of any errors or discrepancies
you find in the data posted to DART. Also, if you are aware of additional data
for Prosser and/or Roza Dams that you feel should be loaded to DART, by all
means please forward your contribution to us.
Thank You.
