This session introduces the Flow Photo Explorer (FPE)—a USGS tool that uses time-lapse trail camera images to estimate relative streamflow dynamics, especially in ungagged streams and now deployed at 600+ locations. We’ll show how simple imagery can be turned into flow models and highlight ongoing work expanding these methods. The session includes a live demo of the platform so you can see how it works in practice, along with examples of where it’s been useful and what’s coming next.
