Precipitation in KRIS Projects

The amount of precipitation has a direct relationship to stream flows and the amount of fish habitat available in any given year. KRIS captures rainfall and snowfall data from the U.S. Geologic Survey and the California Department of Water Resources, through the California Data Exchange Center. The KRIS database allows for the review of all long-term rainfall and snowfall data in the geographic area proximate to projects. These records can be examined to see peak precipitation associated with large storm events and floods or for drought sequences. Gauges results from different locations can also be contrasted to see how storm intensity varies over the landscape. These data also allow assembly of precipitation models that show how it is distributed over the land.
