Alaska (Cook Inlet Basin only)
StreamStats is available for in Alaska only for the Cook Inlet Basin. This application provides the abilities delineate drainage basins at user selected sites, determine the drainage area and the basin average mean annual precipitation for 1971 to 2000 from the PRISM climate dataset, and estimate the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual peak-flow exceedance probability discharges using regression equations from the below report:
