Lower Colorado River Historical Stream Flow Reports
Each year, the Bureau of Reclamation collects, computes, and reports streamflow data from a network of gaging stations between Davis Dam and the international boundary with Mexico. Each gaging station in this network generates hourly "provisional" data which is reviewed, analyzed and adjusted to create the "final" data documented in these annual reports.
Note: All reports are formatted as Adobe Acrobat PDF files
