USGS National Water Quality Network (NWQN-SW): Overview of Sample Collection, Data Reporting and Products

Wednesday July 22, 2026 8:00am - 8:20am CDT

BCC - Central Bank (39 Class / 60 Theater)

Understanding the water quality of U.S. streams and rivers requires consistent data collection and analysis over decades. The U.S. Geological Survey’s National Water Quality Network (NWQN) was established to facilitate national-scale understanding of surface-water quality conditions through the collection of comparable data in large rivers and small streams in different geographic and land-use settings. Data collected by the NWQN supports the needs of Federal, State and local stakeholders tasked with managing our Nation’s water resources. This talk will provide an overview of the history of national-scale, surface-water quality monitoring in the USGS, current network objectives and scope, sample collection and reporting methods, sampling resources as well as highlight products utilizing NWQN data.

Hydroacoustic Streamflow Measurements: Selecting Equipment and Methods

Wednesday July 22, 2026 8:00am - 8:20am CDT

BCC - Birmingham (65 Class / 100 theater)

A common question is how to choose streamflow measurement methods and equipment for different flow conditions. Should the stream be waded? Should the measurement be made with moving boat ADCP or Mid-Section ADCP? What track reference should I use if the moving boat ADCP method is used? This presentation will cover the limitations of each approach and introduce a simplified decision matrix for selecting methods and instruments.

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.

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

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.

Using the Fixed Method for Open Water Mid-Section ADCP Measurements

Wednesday July 22, 2026 11:00am - 11:20am CDT

BCC - Birmingham (65 Class / 100 theater)

The fixed method for making mid-section ADCP measurements is traditionally used for under ice conditions. The fixed method could be adapted to use in open water when other methods will not work due to the inability to safely get top-down observations, magnetic interference, and time constraints. This talk will discuss a situation where the fixed mid-section ADCP method was used in open water when no other viable option was available for making discharge measurements.

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

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.

Listening Session – Ideas for integrating satellite imagery with existing workflows and applications

Wednesday July 22, 2026 4:00pm - 4:50pm CDT

BCC - Smith (28 Class / 45 Theater)

High resolution satellite data has the potential to enhance situational awareness, aid in interpreting signals from monitoring stations, and in understanding environmental conditions when working records. However, access to high resolution satellite imagery is currently separate from most day-to-day workflows for field staff. In this listening session we will review available high resolution satellite imagery, gather ideas of how they might be used in field operations and records processing, and explore where they might plug into existing applications. Through collaborative idea generation, we will explore the question "In day-to-day workflows, where and how would it be helpful to have satellite imagery available?” The outcome will be a collective vision of a future where satellite data are delivered at the point(s) of greatest utility to support mission essential hydrologic monitoring tasks.
