Whether you manage water districts, model floodplains, or analyze watersheds, Arc Hydro remains one of the most powerful extensions ever built for ArcMap.
If the official download links are no longer available due to Esri’s version sunset, the GitHub repository and UT Austin CRWR archive are your best bets. Install carefully, test with a small DEM, and you’ll be generating stream networks and catchments in minutes.
