Want a (sometimes) easy button for developing estimates during records processing? Try the AQTS Automatic Estimation correction to quickly generate estimates at your sites. Presentation will cover proper usage, recent improvements, tips and tricks, and things to watch out for to help get the most out of the correction and help save you time during records processing.

This Show and Tell session provides an introductory tour of the modernized USGS Water Data for the Nation interface and tools available at waterdata.usgs.gov.

The setup and quality assurance of acoustic Doppler current profilers (ADCPs) involve multiple steps preceding streamflow measurement activities. Reliable heading data is essential for Loop Method Moving Bed Tests, GPS-based navigation, and angle calculations in the Azimuth Mid-Section method. This presentation will address the use of both internal and external heading sensors, highlight the significance of accurate heading data, and outline quality assurance procedures applicable during data collection and post-processing.

This session dives into practical techniques for installing and maintaining surface‑water gages and continuous water‑quality stations. Unique equipment setup, and lessons learned from the field. The session is designed to be interactive and audience‑driven—attendees are encouraged to share their own methods, challenges, and troubleshooting experiences. If you have a tricky site or ongoing problem, bring it to the group and let’s talk through it together.

How do you do? - Gage Installs for Surface Water and Continuous Water‑Quality Monitoring 

This session will highlight some general best practices when flagging, surveying, and computing indirect measurements of peak discharge, as well as identifying some common (and uncommon) mistakes.

The USGS Continuous Water-Quality community maintains a large network of real-time instruments. Throughout the country, the USGS is collecting over 6,000 continuous water-quality datasets at over 2,500 sites and measuring more than 8 water-quality parameters (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate, chlorophyll, and Fluorescent Dissolved Organic Matter (fDOM)). Discover what CWQ resources are available for staff, who to contact with questions or suggestions, and what efforts are in progress.

Do you have questions about Go2? The modernized Go2 replaced deprecated legacy Go2 scripts to send alerts to field staff about transmission problems, erroneous data, and measurements needed based on current conditions. This session will include hands-on training to set up, customize, and troubleshoot modernized Go2 configurations. We will cover frequently asked questions and tips and tricks for Go2 setup. We want to see varied use cases - bring any questions, suggestions, and issues, and we will work through them. Hydrographers and data managers will gain the skills and knowledge needed to use Go2 for improved site monitoring and management.

Overview of the cause and effect of a moving bed and methods to identify and correct for a moving bed when measuring discharge with an ADCP from a moving boat. This talk will also include a review of the moving-bed test results and what they mean.

This session provides an overview of the current policy landscape for image velocimetry (IVy) within the USGS, with emphasis on Operational Quality Assurance (OQA) expectations and the process for aligning IVy methods with approved national standards. We will discuss where IVy techniques currently stand in the method-approval pipeline, outline the steps required to transition research workflows into fully supported operational methods, and highlight ongoing efforts to ensure consistent, defensible applications across the WMA. Attendees will gain clarity on documentation requirements, approvals, and future guidance that will shape the public release and operational use of IVy tools and products, as well as have the opportunity to share their feedback and needs with leadership.

Submersible pressure transducers such as Onset HOBO and Van Essen Diver data loggers can provide valuable stage data when compensated with barometric pressure readings. However, when submersible transducers are deployed in the air, they often prove unreliable as verification for stage records within set uncertainty limits. This unreliability comes from overlapping uncertainties of air pressure readings made by both the absolute and barometric pressure sensors. This talk proposes implementing a new computational method and tool during the compensation process involving the average misalignment between air readings made by both pressure sensors and adjusting all readings within a file by that misalignment. Preliminary results have been promising with most of the affected data aligning closer to verification stage records. This method will enable air-deployment of submersible pressure transducers to be more reliable as a method for peak-stage verification as well as increase the accuracy of air-deployed submersible pressure transducers without secondary data sources, such as tidal records and temporary gage deployments. To streamline the processing of data collected by submersible pressure transducers, we have developed a shiny app that implements this proposed new method automatically when processing air deployments in addition to allowing the processing of submersible pressure transducers via existing methods. This application is intended to produce more accurate data records by using a consistent compensation method between different sensor models while reducing the workload of the user processing the data.

Learn more about the USGS Continuous Water-Quality Community at this facilitated networking session. Meet your colleagues, make contacts, and discuss parameters and processes. Ever wish you had more time to ask peers about equipment or a challenge? Great ideas often come by having conversations with people about a shared problem or interest. During this session, employees will get the opportunity to share perspectives with a subset of peers working on the same topics.

A presentation on how to pick the best ADVM mount design for your index velocity site with an emphasis on sites that are flashy in nature. Traditional mount designs tend to favor slower tidal environments that aren't always built to withstand debris hitting them at higher velocities. This talk will go over creative solutions, what not to do, and show off successful ADVM mounts from complex environments. Other considerations for flashy IV sites will also be discussed.

WaterMAP (https://apps.usgs.gov/watermap) is an interactive web application that brings together comprehensive views of surface water conditions in rivers, lakes, and reservoirs, everywhere in the US. The application allows users to explore water conditions over time using both satellite observations and onsite measurements. We will demonstrate best practices to leverage and integrate each data catalog while highlighting the interactive mapping and visualization capabilities, as well as data search/filter/download functionalities. Live demos will present use cases to improve workflows for USGS hydrologic technicians and scientists. Data product owners and the development team will be available to answer questions.

This session offers a practical, end‑to‑end demonstration of the National Image Management System (NIMS) and the Hydrologic Imagery Visualization and Information System (HIVIS) web application. We will begin by walking through how camera stations are added, edited, and managed within the NIMS Admin Console, highlighting tools for configuration, metadata editing, and system monitoring. The demo then transitions to the HIVIS front‑end application, where we will showcase recent interface updates, new visualization capabilities, and streamlined workflows for viewing and interrogating hydrologic image data. Participants will also be introduced to the broader NIMS API and the pyNIMS Python module, with examples of how these resources enable programmatic access for analysis, automation, and integration with other tools. The session concludes with a brief look at features planned for release this year—including advancements in the AAA process and other workflow enhancements—to give users a clear view of what’s coming next.
