A gauging station was installed in Carnivore Creek during the following months/years during three field seasons: May-August 2015, May-August 2016, May-August 2017, and May-August 2018. During the 2015, 2016, and 2017 field seasons, water pressure, turbidity, temperature and conductivity measurements were acquired every 30-60 minutes using a Troll9500 (raw data). Back-up measurements for pressure and temperature for datasets in 2015, 2016, and 2017, as well as the entire 2018 dataset, were acquired using a Hobo Water Level Logger - U20L-03. Water pressure was corrected for atmospheric pressure and converted to water level, and a discharge (Q) rating curve was built for each field season by acquiring periodic discharge measurements using an hand held Hach FH950 flow meter. These continuous measurements and calculations are available in the following file: "CAR_Q_continuous". Water samples were collected during the discharge measurements using a DH-48 and suspended sediment concentration (SSC) was obtained from filtration of the water samples. These manual measurements are available in the following file: "CAR_Q_SSC_manual". The 2015 Q dataset was extended by analyzing daily photographs of the river gaging station. The study, as well as detailed 2015 and 2016 datasets, is described in a MS thesis: Thurston, L.L., 2017.
