Continuous water quality data from the Purgatory River below Trinidad Reservoir, Colorado, USA, 2020-ongoing

This data resource contains continuous water quality measurements (water temperature, specific conductance, turbidity, pH, dissolved oxygen) from the Purgatory River downstream of the Trinidad Lake Reservoir in southcentral Colorado, USA. These data support the U.S. Army Corps of Engineers (USACE) Albuquerque District Reservoir Operations by quantifying the delivery of sediment to Trinidad Reservoir as well as impacts of the reservoir on sediment retention and water quality. This site is located immediately downstream of the U.S. Geological Survey (USGS) gage \"Purgatoire River Below Trinidad Lake, CO (07124410).\" Data were collected using a YSI EXO3 sonde, deployed in an ~8’ aluminum casing bolted to a concrete weir. Data collection is ongoing, with this release spanning March 25, 2021 through June 30, 2024.
