Near-surface geophysical data collected in the Sunflower Drain study area near Delta, Colorado, March 2018 Near-surface geophysical surveys were conducted during March 2018 in an irrigated agricultural drainage near Delta, Colorado, locally know as Sunflower Drain. This data release presents results of two surveys, one using fiber-optic distributed temperature sensing (FO-DTS) and the second using a horizontal-to-vertical spectral ratio (HVSR) passive seismic method. For the FO-DTS, a temperature sensitive armored cable with a spatial resolution of 3.31 feet (1.01 meter) was deployed along a 0.3 mile reach of Sunflower Drain. Data were collected and processed using an Oryx model SR Remote Logging DTS unit (Sensornet, 2020) run over a 48-hour period and integrated at 10-minute intervals. The DTS data are provided in two...

The data set includes nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, turbidity, and chlorophyll . Data-collection cruises were conducted under three different environmental/flow conditions in August, September, and October 2018 that coincided with conditions prior to, during, and following a directed flow action or pulse of agricultural return water organized by the California Department of Water Resources and California Natural Resources Agency...
