Version 3 is now available for all states
StreamStats version 3 is now available for all states. Version 2 has been retired. Currently, version 3 can only delineate drainage basins, compute basin characteristics, and estimate streamflow statistics using regression equations for user-selected sites. It also can provide reports of information for USGS data-collection stations. All other functionality that previously was available in version 2 will be added to version 3 as quickly as possible, with a goal of having all functionality available by the end of 2015.
Please help us conserve our server system resources by closing the Interactive Map window when you are finished using it. Doing so will help ensure system availability for all users. Thank you.
Also, please bookmark this page rather than the Interactive Map page, as the URL for the interactive map may change in the future.
Two reports document the regression equations available in StreamStats for Washington, the errors associated with the estimates, and the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
