Version History for U.S. Geological Survey Open-File Report 2023-1032 Re-Prioritization of the U.S. Geological Survey Federal Priority Streamgage Network, 2022 By Jonathan J.A. Dillow, Brian E. McCallum, and Cory E. Angeroth ----------------------------------------------------- First posted online April 13, 2023 ----------------------------------------------------- Revised and reposted April 4, 2025 as version 1.1 In the Abbreviations list, added "WSC Water Science Center" In the Abstract section, added "(NSIP)" after National Streamflow Information Program in the first sentence of the first paragraph In the Abstract section, changed "October 2020" to "October 2021" in the second sentence of the first paragraph In the Abstract section, added the following text to the second paragraph of the Abstract section: "Results of the FPS Re-Prioritization Project and Open Season that ended in May 2024 revealed that the number of FPS locations meeting the updated eligibility criteria nearly tripled, which illustrates the value of the information provided by the FPS network. The Water Forecasting & Operations and the Water Quality network priorities contributed to the largest number of new eligible FPS sites, demonstrating the importance of the FPS network in supporting informed decisions related to the protection of life, property, the environment, and the economy of the United States." In the Introduction Section after the last paragraph of this section added the text: "This report has been revised to include a description of the implementation of the new FPS priorities established by the Re-Prioritization Project. This implementation phase, called the FPS Open Season, involved reassessing the entire existing USGS streamgaging network, as well as the eligibility of potential new streamgage locations for inclusion in the updated FPS network design. The FPS Open Season lasted from December 2023 through May 2024, and involved staff from all USGS WSC offices engaging with their local federal partners to submit a list of proposed streamgage locations for inclusion in the 2024 FPS network design according to provided guidance. Submissions were assimilated and reviewed by the FPS Advisory Group who then finalized the 2024 FPS network design that is published in this report revision. Results of the Re-Prioritization and Open Season revealed that the number of FPS locations meeting the updated eligibility criteria nearly tripled, which illustrates the current value of the information provided by the FPS network related to the protection of life, property, the environment, and the economy of the United States." In the Background section, replaced "Streamflow" with "Streamgaging" in the first sentence of the second paragraph and replaced "As a federally funded network within the National Streamflow Network" with "The" in the second sentence of the second paragraph In the Results section, added the subsection "The FPS Open Season" In the Results section of the FPS Open Season section on page 13, changed to the text for the Water Forecasting & Operations priority paragraph: the number of locations changed to 4,900. In the Summary section, added the following sentence at the end of the paragraph: "The FPS Open Season occurred from December 1, 2023 to May 31, 2024 and used a collaborative process with federal partners to evaluate the existing FPS network locations and potential new locations according to the new site selection criteria. The FPS Open Season network evaluation resulted in a new 2024 FPS network design. Results of the Re-Prioritization and Open Season revealed that the number of FPS locations meeting the updated eligibility criteria nearly tripled, which illustrates the current value and critical need of the FPS network. The Water Forecasting & Operations and the Water Quality network priorities contributed to the largest number of new eligible FPS sites, demonstrating the importance the FPS network in supporting informed decisions related to the protection of life, property, the environment, and the economy of the United States." In the Summary section, replaced "require" with "required" in the fifth sentence of the first paragraph In the References Cited section in the third reference, added "Brent Ache, National Ocean Service, written communication, 2023." In the colophon section, replaced "West Trenton" with "Baltimore"
