Hurricane Helene - Impact and Recovery Efforts at the Asheville Field Office
Tuesday July 21, 2026 1:00pm - 2:20pm CDT
Hurricane Helene severely impacted the Asheville Field Area. This presentation looks at impacts from the storm as well as recovery efforts that were undertaken by Asheville Field Office staff as well as assistance from many outside sources. This (hopefully) once in a lifetime storm event led to significant damage and loss of data. Significant effort was put into restoring the network, assigning peak gage heights, and conducting indirect measurements to compute discharge data through the event.

Alpha Coefficient Data Mining for Image Velocimetry from the USGS Database of ADCP Measurements
Tuesday July 21, 2026 1:30pm - 1:50pm CDT
To compute discharge using image velocimetry, the measured surface velocity must be related to the depth-averaged velocity; this is typically done using a simple coefficient known as the alpha coefficient. The alpha coefficient is the most significant input to the computation of discharge from imagery that is often not empirically determined, but the resulting discharge value is directly proportional to the value chosen. The USGS database contains more than half a million ADCP measurements - the profiles in these measurements can be used to inform selection of alpha. Results from a compilation of profiles at a variety of sites will be presented.

Water, Watts, and Wires: An Introduction to Microcontrollers for Instrument Control and Monitoring
Tuesday July 21, 2026 2:00pm - 2:20pm CDT
"Did you unplug it and plug it back in?" - every IT Person, ever.
Field visits for simple instrument resets are a costly drain on resources. While most dataloggers have control ports that can power cycle devices and instruments, these ports are often exhausted as sensor density increases. By integrating a microcontroller, we have expanded our control capacity via multi-channel relay boards. Logic within the main datalogger verifies data transmission, validity, and connectivity before communicating with an external microcontroller that manages the power supply to individual devices and instruments. More importantly, we've moved beyond simple "On/Off" control by monitoring individual instrument's current draw in real-time. These data are passed to the primary datalogger, enabling automated notifications if hardware is drawing outside of specifications. Because the entire system can be monitored and controlled remotely, it provides a comprehensive "health check". This reduces unnecessary field visits and equips staff with additional diagnostic information needed to troubleshoot before leaving the office.

USGS Water Data in Relation to the Fundamental Science Practices
Tuesday July 21, 2026 3:00pm - 3:20pm CDT
The USGS has collected water data for over 135 years. The USGS Fundamental Science Practices (FSP) have been governing water data collection and publication for the past 20 years. How familiar are you with FSP as it pertains to water data? This presentation will (1) provide a broad overview of FSP, (2) show how FSP relates to water data collection and subsequent data publication, and (3) share available OSQI resources useful for when FSP questions arise.

This presentation will accomplish these objectives by examining three focus areas; (1) discussing data collection and approval obligations in SM 502.2 Fundamental Science Practices: Planning and Conducting Data Collection and Research and SM 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release, (2) relating adherence of Water Mission Area Techniques and Methods to adherence of Fundamental Science Practices, (3) discussing mechanisms for reporting FSP questions to the Fundamental Science Practices Advisory Council (FSPAC), quality concerns to OSQI resources, and integrity concerns to the USGS Scientific Integrity Officer. Listeners will leave the presentation with a better understanding of how FSP relates to USGS Water data collection and publication and where to turn to when concerns arise.

This presentation will be given by Gary Burke, a staff scientist from the Office of Science Quality and Integrity (OSQI). Gary was a Field Office Chief for over 6 years prior to joining OSQI and had collected NWIS water data for over 20 years.

Stream2Screen: Streamlining Gage Management with a Real-Time Push Notification System
Wednesday July 22, 2026 9:00am - 9:20am CDT
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.

ICE-Edge: Computing Continuous Under-ice Discharge on the Edge
Wednesday July 22, 2026 10:00am - 10:20am CDT
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
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.

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
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.

From Field Survey to Plotted Cross-Section: SVMobileAQ Data Collection and AreaComp3 Visualization
Thursday July 23, 2026 8:00am - 8:50am CDT
Accurate and efficient cross-section surveys are essential for maintaining high-quality stage-discharge ratings and index velocity gage operations. This presentation demonstrates a streamlined workflow for conducting differential level surveys of river cross-sections using the SVMobileAQ mobile application and importing the data into AreaComp3 software for visualization and analysis.
The session will cover the fundamentals of setting up a conventional differential level instrument (level gun) and collecting cross-section data in the field with SVMobileAQ. Attendees will then learn how to seamlessly import the survey data into AreaComp3 to generate plotted cross-sections referenced to gage datum.
Although commonly applied to index velocity gages, this approach provides broader benefits for streamgaging programs, including evaluation of control features at stage-discharge stations, detection of changes in channel geometry through overlay of historical surveys, and investigation of discrepancies by comparing survey results with ADCP bathymetry.
This practical, field-to-office workflow offers an accessible and efficient method for improving the quality and utility of cross-section data in water resources monitoring.

Peak Precision from Your Desk: In-Office Validation of the Upper End of Stage-Discharge Rating Curves
Thursday July 23, 2026 1:30pm - 2:20pm CDT
Developing reliable upper-end extensions of stage-discharge rating curves is often challenging due to limited high-flow measurements. This presentation outlines a clear hierarchy of preferred approaches—starting with direct flow measurements, followed by indirect methods—and then focuses on practical in-office techniques that can be performed without field work. Methods include estimating peak flows using areal regression (Q vs. drainage area), transferring peak discharges from upstream or downstream gages, and leveraging the StreamStats cross-section cutting tool along with the AreaComp3 software program to generate control and channel geometry. These desk-based strategies allow hydrologists to effectively vet rating descriptor pairs, assess curve shape, and confidently extend ratings to higher stages.
