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.

Fulfilling Our Mission (Life & Property), One Gage at a Time: USGS Real-time Flood Impact Map Workshop
Tuesday July 21, 2026 3:00pm - 4:20pm CDT
Since 2021, the USGS Real-time Flood Impact Map has evolved through the Next Generation Water Observing System (NGWOS) into an increasingly operational capability that delivers actionable flood impact intelligence.

This hands-on workshop will train participants to enter and document flood impacts within the system. Attendees are encouraged to bring their own flood impact scenarios; alternatively, examples may be selected from National Weather Service flood impact statements. These scenarios will be used for guided, step-by-step instruction on data entry, standards, and quality assurance.

The session will include: (1) an overview of the Real-time Flood Impact Map, (2) criteria for defining and selecting flood impacts, (3) hands-on data entry exercises, and (4) best practices for ensuring consistency and accuracy. The map currently includes more than 6,000 documented flood impacts nationwide and continues to expand in operational use.

Participants will leave prepared to independently contribute high-quality flood impact data and support broader adoption across cooperators and stakeholders.

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.

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.
