History and Current Activities of the Federal Interagency Sedimentation Project
Wednesday July 22, 2026 8:00am - 8:20am CDT
BCC - Nichols (21 Class / 40 Theater)
The Federal Interagency Sedimentation Project (FISP) was founded in 1939 to standardize sediment sampler instrumentation, sampling methods, and sediment sample laboratory analysis processes. The project expanded over the many years of its operation to include automatic samplers, surrogate instrumentation such as acoustics and turbidity meters, water quality samplers, and much more.
This session will cover the history, achievements, and current projects the FISP is working on.

A Solution Thirty Years in the Making: The Fargo-Moorhead Diversion Project
Wednesday July 22, 2026 8:00am - 8:50am CDT
BCC - Smith (28 Class / 45 Theater)
After the devastation of the 1997 flood, there was agreement in the Fargo-Moorhead community that something needed to be done to prevent a repeat of the catastrophic damages. Planning began for what would become the FM Area Diversion. The process has included studies, permits, Congressional action and hard work from many key entities, including the USGS. Now, the community is on track to have permanent, reliable flood protection by 2027. This presentation will outline the project and USGS's involvement leading up to, during, and post project development.

Stream2Screen: Streamlining Gage Management with a Real-Time Push Notification System
Wednesday July 22, 2026 9:00am - 9:20am CDT
BCC - Mason (33 Class / 60 Theater)
Efficiency isn't just a goal-- it's a necessity when managing a large network of gages. Manual checks and generic station-health emails are so last century.
We've integrated custom programming into our internet-connected dataloggers to improve our standard monitoring workflow. By utilizing an open-source web server and HTTP PUSH/POST methods, we send push notifications to "subscribed" users. Notifications are completely customizable and end-users only "subscribe" to gages that they run or are interested in. They receive instant notifications if there are instrument-specific issues, total system failures or peaks in parameters that should be targeted. With custom messaging, we also build in troubleshooting tech-tips. No more generic "Low Battery" message; users get specific messaging containing diagnostic tips and the likely culprit for the issue or failure. Our gages don't just record data; they advocate for their own maintenance and targeted sample scheduling.

Let's Work Together - USGS Flood Coordination
Wednesday July 22, 2026 10:00am - 10:20am CDT
BCC - Nichols (21 Class / 40 Theater)
Flood Coordination helps facilitate clear, consistent cross‑organizational situational awareness through routine flood coordination calls (internal operational calls and external science calls), updates to Emergency Management and USGS leadership, and participation in interagency briefings, but it doesn't work unless we work together. I would like to present the current approach and am looking for your feedback.

IVyTools — Is it accurate?
Wednesday July 22, 2026 2:30pm - 3:20pm CDT
BCC - Central Bank (39 Class / 60 Theater)
This session presents recent validation results for IVyTools and evaluates the performance of Space-Time Image Velocimetry (STIV) methods across a range of hydraulic conditions. We will review findings from our internal comparison study, highlight accuracy metrics derived from controlled field and laboratory datasets, and demonstrate how the Comparison Measurement Database supports transparent evaluation of IVy-derived velocities. The session will also introduce the latest improvements to IVyTools processing workflows, including enhanced guidance on interpreting “dots” visualizations for QA/QC. Attendees will gain a clearer understanding of the strengths, limitations, and reliability of STIV-based velocity measurements and how to apply the tools confidently in operational settings.

10 Things I Hate About NWDi/WADERS
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
BCC - Central Bank (39 Class / 60 Theater)
The NWDi development team wants to hear why you don’t use NWDi/WADERS and roadblocks/usability issues you come up against. We want to hear your ideas for enhancements. NWDi team plans to take these ideas/issues to drive development and communication on the application.

NWDi/WADERS is an interactive web application that brings together an array of data and approaches to view and manage the USGS water network operations and internal business operational systems in a unified, standardized way for real-time management, resource planning, and situational awareness.

Flow Photo Explorer: Using Trail Cameras to Estimate Streamflow Dynamics
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
BCC - Mason (33 Class / 60 Theater)
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.

USGS peak-flow data is one of the most important datasets used to assess flood risk in the United States. This presentation will discuss tools for visualizing USGS peak-flow data and indirect discharge measurements to improve accessibility of USGS flood data. These tools can be used to easily find what USGS peak-flow data are available in an area to inform operations during and after floods events and identify data for use in flood frequency studies.

Using AreaComp3 for Indirect measurements
Wednesday July 22, 2026 4:30pm - 4:50pm CDT
BCC - Birmingham (65 Class / 100 theater)
AreaComp3 was primarily developed to assist with development of Stage-Area ratings for index velocity sites. The program has several other improvements that can assist with the computation of Indirect measurements, specifically Contracted Opening and Critical Depth measurements. This brief presentation will discuss the use of the AreaComp3 tool with X,Y,Z data, and how you can use that output to assist with the computation of Indirect Measurements. This presentation is geared towards users that collect cross section data post flood and need to compute hydrologic properties with that data. It is also oriented towards technicians/hydrologists that work with Indirect Measurements of Discharge and should be familiar with those methods.
