High-Water Mark Data from the July 2023 Flood in Vermont
A major rain event caused catastrophic flooding from July 9 through 12, 2023 in various portions of the State of Vermont, resulting in millions of dollars of damage. These data are one of three datasets in the Vermont Flood of July 2023 Data data release. This part of the data release contains high-water mark (HWM) data from the Vermont flood of July 2023. The Comma-Separated Values (CSV) file table_JulyHWMs.csv contains 547 surveyed HWMs on 31 rivers from the Vermont flood of July 2023. In addition, a comparison between surveyed HWM data from the July 2023 flood and from Tropical Storm Irene in 2011 is included in the data release. The data from the two events--where HWMs were co-located and surveyed--are compared in the file table_HWMcompare.csv. Elevation differences were calculated as the July 2023 HWM surveyed elevation minus Tropical Storm Irene HWM surveyed elevation at the same site. Sites are defined as areas on a river that are expected to have the same hydraulic setting, for example, immediately downstream of a bridge.
These data are also hosted on the USGS Flood Event Viewer (https://stn.wim.usgs.gov/FEV/).
