Colorado River Basin Natural Flow and Salt Data
This natural flow data for the Colorado River Basin is currently being used for modeling purposes in the Colorado River Simulation System (CRSS).
Please note that even though natural flow data is termed "current," it is SUBJECT TO CHANGE over the entire record due to source data updates.
Presently, the consumptive uses and losses data from 2006-2016 used to compute natural flow are PROVISIONAL and will be revised in the future. These revisions will change the natural flow computation.
