Colorado River Basin Natural Flow and Salt Data
The information contained in the following web pages is of a technical nature. It is intended for use by those in the scientific and water resources communities interested in natural flow and salt computations in the Colorado River Basin. These data are furnished by the Bureau of Reclamation for use as hydrologic inputs to the Colorado River Simulation (CRSS) long-term planning and operations model.
Natural flow data is termed 'CURRENT' when it is currently being used for modeling purposes in 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 2006-2015 used to compute natural flow are PROVISIONAL and will be revised in the future. These revisions will change the natural flow computation.
