Cableways – Overview, maintenance, and best practices
Wednesday July 22, 2026 8:00am - 9:20am CDT
Cableways are essential facilities for obtaining streamflow measurements and water quality samples at many USGS streamgages. This presentation will give an overview of the primary components of cableways and discuss best practices for cableway maintenance and safe operation.

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.
