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.

Help Us Curate a Stronger National Groundwater Monitoring Network
Wednesday July 22, 2026 8:30am - 8:50am CDT
Hotel Capstone - Presidents (50 Theater/40 Classroom)
The National Groundwater Monitoring Network (NGWMN) is a compilation of selected groundwater monitoring wells from Federal, State, and local groundwater monitoring networks across the nation. The NGWMN is designed to be a curated network of wells that are of known quality and can provide insight to groundwater araciality. The NGWMN Data Portal provides access to data in the Network; monitoring locations must be added to the network through a manual process. Each Water Science Center can select wells they deem appropriate for inclusion in the NGWMN. This session will cover criteria for wells to include in the NGWMN, give tips on how to determine if wells should be added or deleted, and review the application that can be used for this process.

Readying Superfly for LIMS Modernization and Other Updates
Wednesday July 22, 2026 10:00am - 10:20am CDT
BCC - Central Bank (39 Class / 60 Theater)
The upcoming modernization of LIMS will require modifications to the Superfly files we use to generate ASRs. More broadly, the modernization of many of our tools creates opportunities for Superfly to become more integrated into the Discrete Water Quality Workflow. This session will talk about how Superfly is being updated and how users can prepare accordingly.

USGS Signage Updates: Coordinating Across HIF, WSCs, and the Innovation Depot
Wednesday July 22, 2026 10:00am - 10:20am CDT
BCC - Mobile (33 Class / 60 Theater)
Join us to learn more about USGS signage! An USGS team is working on a new line of standardized, field ruggedized signage designed specifically for Monitoring Locations, with production coordinated through the Hydrologic Instrumentation Facility (HIF). The goal is to allow Water Science Centers to order signs. The initial design concept includes a sign sized approximately 12 by 18 inches. Centers will be able to tailor their signs through a range of construction options—including aluminum or vinyl signs, pre-drilled mounting configurations, acrylic protective covers, and optional aluminum back plates.

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.

Connecting the Triangle of Superfly - LIMS - and AQS
Wednesday July 22, 2026 10:30am - 10:50am CDT
BCC - Central Bank (39 Class / 60 Theater)
It costs us time trying to get our Discrete Water Quality applications to talk to one another as data moves through the workflow. The modernization of those applications provides an opportunity to strengthen those connections and hopefully save us some time. This presentation will describe some of the ways that new connections are being built into those applications and how our workflow will tap into those new features.

As LabVantage replaces the StarLIMS system at the National Water Quality Laboratory, the format of data sent to AQUARIUS Samples will shift significantly from today’s QWBATCH structure. This session will explain how LabVantage’s outputs align more closely with AQS’s Observations format, what differences users can expect in the new data model, how these changes enable features and capabilities that were not possible with QWBATCH, and what new constraints will be present in the data flow.

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.
