New Limited-Use Method for the Collection of Low Precision (0.1 ft) Stage Data
Thursday July 23, 2026 8:00am - 8:50am CDT
Limited-Use methods are collected and/or reviewed using non-standard methods, which may include modifications to a standard method, differences in quality assurance procedures, and(or) following external methods with limited validation information pertaining to a particular use or context. The low precision, or 0.1ft, stage data method establishes the procedural framework for these modification. The method provides a complete description of the requirements for site establishment, as well as the data collection and data processing quality assurance/quality control procedures.
This session will discuss these requirements and examine how the new method's modifications impact data quality compared to the standard methods currently collected under the parameter Gage height.

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.

An Introduction to Electromagnetic Methods and the Horizontal-to-Vertical Spectral Ratio technique
Thursday July 23, 2026 8:00am - 8:50am CDT
This talk is a hands on introduction to three geophysical methods, time-domain and frequency-domain electromagnetic (TDEM and FDEM) methods, along with the horizontal to vertical spectral ratio (HVSR) method that are increasingly useful for groundwater investigations. We focus on how these methods work, what they measure, how they’re deployed in the field, and the subsurface information they provide. Case studies highlight how electromagnetic methods can map subsurface conductivity and characterize aquifers, and how the HVSR passive seismic technique helps estimate sediment thickness overlying bedrock, an important input for groundwater modeling.

Like a lot of things, the Unified Field App (UFA) project has navigated several challenges in the last year. This means we've had to push the groundwater module release date until sometime well into 2027. 

Despite these setbacks, the team has kept momentum moving forward. We're using 2026 to re-group, refine our strategy, and set the project up for success in 2027 and beyond.  

Most importantly, the project is still moving forward (though slower than planned) and is recognized as a high priority. We appreciate your patience and continued enthusiasm.

Use of Remote Boats with ADCPs
Thursday July 23, 2026 10:00am - 10:20am CDT
Remote control (RC) boats are increasingly used to deploy acoustic Doppler current profilers (ADCPs) for streamflow measurements. These platforms can enhance safety, reduce operational costs, and improve field efficiency. However, they also introduce potential data quality concerns. Additional quality assurance is required to detect and mitigate issues such as electromagnetic interference, air entrainment, and flow disturbance.
This presentation will outline the advantages and limitations of RC boat based ADCP deployments, present examples of both high and low quality datasets, and highlight practical steps users can take in the field and during post processing to address common data quality challenges.

Index Velocity Rating Departure Causes from Pitch and Roll
Thursday July 23, 2026 10:30am - 10:50am CDT
Small changes in an ADVM position can cause big problems with your index velocity rating. Changes in pitch and roll can change from poor mount design, broken mounts, debris snags, or ADVM installation error. When pitch and roll changes occur, a different sample volume is measured which can cause departures in your index velocity rating. ADVM movement could be difficult to catch, but reviewing ADVM data in the field can explain and potentially prevent rating issues. This talk will discuss how to identify rating problems caused by changes in pitch and roll along with best practices for shifting index velocity ratings due to pitch and roll.

Analysis of these substances can be used to assess environmental processing of dissolved organic matter (DOM), and also help distinguish sources of water and contaminants. The USGS Organic Matter Research Laboratory in Sacramento, CA, provides a range of analytical services including dissolved organic carbon concentration, and the optical properties of dissolved organic matter (DOM) in water. USGS scientists working with the OMRL have developed proxy models relating fluorescence measurements to a wide spectrum of constituents of concern including PFAS, oil/gas, mercury, and wildfire materials in both surface water and groundwater. These data can also be used to identify which optical instruments are likely to be most suitable for in situ monitoring for specific basins or sites, or if none are available, to develop a novel sensor for the cooperators’ needs.

An Innovative, Tiered, Multi‑Platform Framework for High‑Resolution Water‑Quality Monitoring and Mapping
Thursday July 23, 2026 1:00pm - 1:50pm CDT
An Innovative, Tiered, Multi‑Platform Framework for High‑Resolution Water‑Quality Monitoring and Mapping (NWDTW 2026)

Theresa Armijo, Hydrologic Technician, Colorado Water Science Center
Matt Burgess, Geographer, National Uncrewed Systems Office
Matt Gyves, Physical Scientist, Pennsylvania Water Science Center
Tyler King, Research Hydrologist, Hydrologic Remote Sensing Branch

Effective assessment of water-quality conditions requires strategies that capture spatial and temporal variability and complexities of biogeochemical processes. In this talk we present and seek feedback on a tiered, multi-platform monitoring framework that integrates satellite observations, Uncrewed Aircraft System (UAS)-based hyperspectral imaging, boat-based discrete sampling, in-situ water-quality measurements, and micro-sized autonomous underwater vehicles (AUVs; Jaia Robotics JaiaBot BIO) measurements. Together, these platforms form a scalable and adaptive system for characterizing water-quality dynamics across broad spatial and temporal scales.
This approach will be piloted in August 2026 to characterize conditions in two Colorado reservoirs affected by harmful algal blooms (HABs). Integrating sampling and monitoring technologies within a tiered and multi-platform framework enhances the resolution of water-quality assessments and supports early event detection. This allows for targeted sampling campaigns, and improved mapping of spatially complex environments—including reservoirs, river networks, and estuarine systems.
The multi-platform framework provides an efficient path toward cost-effective, repeatable monitoring, scalable and transferable platforms that can be tailored to diverse management objectives such as site-specific studies to basin-wide or regional initiatives. With this approach, we aim to characterize conditions at increasingly fine resolution.

Visualizing Current Conditions at the state-level with hyswap
Thursday July 23, 2026 1:00pm - 2:20pm CDT
This session introduces a set of state-level Python notebooks that use hyswap to generate maps and charts of current water conditions. These notebooks are designed to be easy to run and modify, providing a practical entry point for creating visuals that were previously available through legacy systems like WaterWatch.

Participants will learn how to produce 7-, 14-, and 28-day percentile maps, along with HUC-based runoff maps, using reproducible workflows that can be adapted to different states or regions. The session will walk through how the notebooks are structured, how they access and process data, and how outputs can be customized for specific communication or analysis needs.

This is a hands-on, work-along session. Attendees are encouraged to bring a laptop and follow along as we get the notebooks running locally, step through the code, and make simple modifications. Support will be provided to help participants set up Python environments and troubleshoot issues so they can continue using the notebooks independently after the session. The session is open to anyone interested in learning how to generate state-level water condition visuals using Python, regardless of prior experience.

Measuring Groundwater flow velocity and direction: Project investigations, long term deployments, and Research and Development of New Multi-dimensional Heat Pulse Flowmeters
Thursday July 23, 2026 1:00pm - 2:20pm CDT
Groundwater flow meters that measure horizontal flow direction and velocity have been used by the USGS in a variety of investigations across the country. Traditionally, these instruments required on-site operation and supported investigative studies of contaminant plumes (such as TCE and PFAS) to aid in site characterization and remedial planning, as well as to evaluate aquifer test responses and production well influence. As part of the NGWOS Illinois Basin Study, groundwater flow meters have been deployed for long-term, telemetered monitoring at two testbed sites to help characterize groundwater flow and direction to assess groundwater–surface water interactions between streams and nearby agricultural areas. Recently, as part of the NGWOS Research and Development sub-program, work has commenced to develop a heat pulse flowmeter that is capable of measuring flow direction and velocity in 3-dimensional space rather than being limited to the horizontal plane. This presentation will provide an overview of available technologies, guidance on proper deployment and operation, case studies, best management practices, and research and development of a new multi-dimensional instrument.

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.
