1. Title: Oak Creek Stream Chemistry, Spring, 2013 2. Context of this dataset: We monitored a suite of stream chemistry parameters for April and May, 2013, at Oak Creek, Oregon, USA. The dataset was collected as a part of the Willamette Water 2100 project, which evaluated how climate change, population growth, and economic growth will change the availability and the use of water in the Willamette River Basin (WRB) on a decadal to centennial timescale. The five-year project began in October 2010, and is a collaborative effort of faculty from Oregon State University (OSU), the University of Oregon (UO), and Portland State University (PSU). These data are also available through the Consortium for the Advancement of Hydrological Science, Inc. (CUAHSI) website (http://cuahsi.org) through the HydroClient (http://data.cuahsi.org/). History of the dataset: This dataset was previously accessible from the The Oregon Hydrologic Information Server, which was an on-line database repository for publication, analysis and retrieval of water related data. The site was administered jointly by the Institute For Natural Resources at Oregon State University and the Oregon State University Library. The server was retired in September of 2018, and the data was made accessible directly through CUAHSI, and through ScholarsArchive at OSU. The original readme file is copied below (section 10) for posterity. 3.

Methods Units for DOC are mg/L; NO3 are mg/L, Turbidity are NTU; SUVA 254 are L/mg/m, specific conductivity are microSiemens/cm, and pH are pH units. We installed the following instruments, all from s::can Measuring Systems. Spectro::lyser – UV/Vis (200 – 750 nm @ 2.5 nm resolution) spectrophotometer for the simultaneous measurement of nitrate, total/dissolved organic carbon, color, turbidity, and UV/Vis spectra. oxi::lyser – fluorescent dissolved oxygen sensor. pH::lyser – pH sensor with automatic temperature compensation. condu::lyser – 4-electrode conductivity sensor with automatic temperature compensation. Data were logged with the con::cube, an industrial controller for data logging. All of the instrumentation was mounted on a panel and supplied with water from Oak Creek, which flowed continuously through the instrument. The sensor suite was installed at the location for over one month. During that time, four grab samples were collected to check the agreement between the sensor and reference values. Samples were analyzed by the Cooperative Chemical Analytical Laboratory (CCAL) at Oregon State University, the same lab used by the HJ Andrews LTER. The grab samples were used to calibrate the sensor results. Samples were taken and delivered to CCAL on 4/25/13, 4/30/13, 5/10/13, and 5/21/13. Samples were taken from the s-can instrument outflow tube. 1-L HDPE bottles were triple-rinsed, sample was taken, and delivered directly to lab within 10 min. Power was lost to the instrument panel between 5/5 – 5/10/2013. Lab methods: All lab results were conducted by a professional chemist at CCAL. See methods page at http://www.ccal.oregonstate.edu/methodology.htm, accessed 11/11/2013. DOC: Method is APHA 5310B on a Shimadzu TOC-VCSH Combustion Analyzer. Specific Conductance: Method is APHA 2510 on a YSI model 3200. Nitrate: Method is AP A 4500-NO3 F on a Technicon Auto-analyzer II. Turbidity: Method is APHA 2130 on a Hach 2100A.

Date of data collection: 201304-201305 8. Funding: The Willamette Water 2100 project was funded predominantly by research grants from the National Science Foundation (NSF) with additional support from the US National Oceanic and Atmospheric Administration (NOAA). Grants included: NSF-EAR 1039192 to Oregon State University, NSF-EAR 103889 to University of Oregon, NSF-EAR 1038925 to Portland State University, and NOAA NA10OAR4310218 to Oregon State University and the University of Oregon 9.
