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.

Remotely Operated Smart Gages
Wednesday July 22, 2026 8:00am - 8:50am CDT
BCC - Lackey (54 Tiered Class Only)
As site loads increase and resources stay tight, many technicians are being asked to manage more than ever before.

This session looks at how modern gaging technology—cameras, remote communications, enhanced power systems, and smarter backend tools—can help ease that burden by reducing unnecessary trips and highlighting what actually needs attention.

ICE-Edge: Computing Continuous Under-ice Discharge on the Edge
Wednesday July 22, 2026 10:00am - 10:20am CDT
BCC - Lackey (54 Tiered Class Only)
As of Jan 5, 2026, 1,185 of the 9,004 USGS streamgages were ice-affected - approximately 13.2% of our assets that lack the capacity to deliver real-time discharge. Existing USGS under-ice methods require hours to complete, are cost prohibitive, lack the capacity to deliver continuous discharge time series, and place hydrographers at risk. ICE-Edge computes real-time under ice discharge on the “edge” (think by the riverbank) by integrating a RaspberryPi (RPi) computer, python code, uplooking Acoustic Doppler Velocity Meter (u-ADVM), FirstNet modem, and leveraging the probability concept discharge algorithm.

What to do after you’ve measured the “big one”: USGS peak-flow data for Hydrologic Technicians
Wednesday July 22, 2026 10:00am - 11:20am CDT
BCC - Wilson (54 Tiered Class Only)
Annual peak streamflow data from USGS streamgages are a critical dataset engineers and hydrologists use for flood frequency analyses that inform bridge designs, floodplain maps, and other projects in and along rivers. Updated Federal guidelines for flood-frequency analysis (Bulletin 17C) were released in 2019, which allow for better use of information published by the USGS, such as censored (greater than or less than) data, and data sources outside of streamgage records, such as historic peaks. In this workshop, attendees will learn how annual peak-flow data are used, what peak flow qualification codes mean and when to use them, what flood information should be included in station descriptions and manuscripts in SIMS, the proper application of “highest since” notes to annual peaks, proper treatment of peak flows at crest-stage gages, and lots of other flood-related facts. An example streamgage will be analyzed with the PeakFQ software to demonstrate application of USGS data to a real-world flood-frequency problem.

Introduction to the Salt Dilution Streamflow Method
Wednesday July 22, 2026 2:30pm - 3:20pm CDT
BCC - Lackey (54 Tiered Class Only)
The salt dilution method is a technique for measuring streamflow by injecting a trace pulse of sodium chloride (NaCl) into a stream, allowing it to fully mix, and tracking the downstream dilution through changes in specific conductance. Because salt dilution performs well in turbulent or irregular flow conditions where velocity–area methods often fail, it is a practical option for difficult‑to‑measure sites. This presentation introduces the salt dilution method, including how to identify suitable site conditions, the core field procedures for making salt dilution measurements, and the principles behind salt dilution discharge calculations.

Discrete Discharge from Multiple Platforms and Novel Algorithms: Fixed‑Mount and Portable Velocity Radars and Drone‑based Cameras
Wednesday July 22, 2026 4:00pm - 4:20pm CDT
BCC - Mobile (33 Class / 60 Theater)
Standard streamgaging methods to compute discharge rely on placing equipment and personnel in water and integrating velocities and depths at multiple verticals at a channel cross section (25 to 30 to hundreds of hydroacoustic ensembles). However, a paradigm change has occurred with the advent of non-contact platforms such as fixed‑mount and portable velocity radars and drone‑based cameras. The benefits of coupling these platforms and novel algorithms are clear – enhanced safety and increased efficiency.

Peak Flow Visualization Tools
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
BCC - Lackey (54 Tiered Class Only)
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.
