Time-lapse imagery, image-derived water-level data, and model archive for three USGS streamgages in Wisconsin during water year 2020

This data release contains supporting materials for a study testing the applicability of an image-derived water-level method at three U.S. Geological Survey (USGS) streamgage sites around Lake Redstone in Wisconsin (site numbers 05404140, 05404150, and 05404147) during Water Year 2020 (Johnson, et al., 2025). Two types of reference objects were tested in this study: white polyvinyl chloride pipes (PVC), and a concrete wall. The PVC pipes were installed an tested at all three sites and the concrete wall was only tested at one site (co-located with one of the white PVC pipes), for a total of four trials. The top-level contents of the data release include: the hourly time-lapse images collected from each of the three sites (images.zip), the model archive of the R code (model_archive.zip) used to derive water-level data from the time-lapse images, a description of the model archive files and how to use them (Model_Archive_README.txt), the results (results.zip) from running the image-derived water-level method for each trial run, and the collated results for each trial (analysis.zip) each of which also include an image suitability judgement determined for every collected image.
