Settled solids were collected from a retention pond and from the incubation room trough. The trough solids likely had been deposited during storm events the previous winter. A third sample was collected in the incubation room, using a continuous flow centrifuge (Conn et al., 2016) to capture suspended particulate material from approximately 700 L of flow-through water over three days. Small particulates escaping the centrifuge were captured on 0.45-micron glass fiber filters. Samples were analyzed for: grain size distribution, percent total carbon and nitrogen, stable isotopes of carbon and nitrogen, carbon-to-nitrogen ratio, mineralogy by x-ray diffraction, and determination of major, minor, and trace elements. Because of mass limitations, only the trough sediment was analyzed for all parameters and other samples were analyzed for a subset of analyses based on available mass and analytical capabilities. Three water samples also were collected - from the creek intake, the retention pond, and the incubation room \u2013 and analyzed for suspended sediment concentration and particle size distribution. The water results are available in the USGS National Water Information System (U.S. Geological Survey, 2024) under the sites: USGS 12102080, USGS 471216122203900, and USGS 471217122203900.\nReferenced citations:\nConn, K.E., Dinicola, R.S., Black, R.W., Cox, S.E., Sheibley, R.W., Foreman, J.R., Senter, C.A., and Peterson, N.T., 2016, Continuous-flow centrifugation to collect suspended sediment for chemical analysis: U.S. Geological Survey Techniques and Methods, book 1, chap.
