The StreamStats Team hosted a webinar on November 28, 2017 titled "Urban StreamStats: The development of data and ArcHydro tool for implementing stormwater networks in StreamStats for St. Louis County and the City of St. Louis" and presented by Rodney Southard (MO WSC) and Tana Haluska (OR WSC, StreamStats Team). The presentation focused on the StormDrain ArcHydro tool that was developed for delineating basins from a network of storm drains and digital elevation model and included information on how the data was processed and developed for use in StreamStats.  The StreamStats Team is working on developing a user interface and separate region for the St. Louis Metropolitan area which will allow users to delineate basins that incorporate both surface runoff and storm drain contributions.
