Semi-continuous pressure and water quality sensor data from 5 locations in Lower Pool 13 of the Upper Mississippi River from May - September 2024

The U.S. Geological Survey Upper Midwest Environmental Sciences Center collected semi-continuous data from water quality and pressure sensors at four shallow locations in the impounded portion of Pool 13 of the Upper Mississippi River and one location upstream near Savanna, IL between late May and early September 2024. This dataset includes high-frequency conductivity, salinity, total dissolved solids, temperature, dissolved oxygen, and turbidity measurements every 5-minutes at five locations, with chlorophyll-a and phycocyanin concentrations being recorded at two of those locations using YSI EXO3 water quality sensors. Pressure data was recorded in bursts every 30-minutes alongside water quality at four locations using RBR virtuoso3 and Nortek Vector sensors to obtain information on local water depth and waves. Due to differing sampling frequencies, data files are grouped by sensor type.
