Beta version 4 maintains the same functionality as version 3 but also provides the ability to edit a delineated basin, modify the computed basin characteristics and re-solve the regression equations to obtain revised estimates of streamflow statistics, measure distances between user-selected points on the map, and obtain elevation profiles between user-selected points along the stream channel on the map.  In addition, StreamStats outputs for user-selected sites now include text boxes for naming the output and adding comments, as well as a map of the delineated basin, which can be re-sized. Users can print the outputs or save them to a shapefile, a file geodatabase, or a .csv file.

Work is still underway to restore several tools that rely on stream-network navigation functionality, which were lost in the transition from version 2 to version 3. Version 2 had to be shut off before re-programming of the network-navigation tools was complete because version 2 ran on obsolete servers that were considered a security threat. The network-navigation tools will be made available in beta version 4 as coding is completed on them, with a goal of having them all completed by September 2016.
