Multiple sampling campaigns were conducted near Boulder, Colorado, to quantify constituent concentrations and loads in Boulder Creek and its tributary, South Boulder Creek. Diel sampling was initiated at approximately 1100 hours on September 17, 2019, and continued until approximately 2300 hours on September 18, 2019. During this time period, samples were collected at two locations on Boulder Creek approximately every 3.5 hours to quantify the diel variability of constituent concentrations at low flow. Synoptic sampling campaigns on South Boulder Creek and Boulder Creek were conducted October 15-18, 2019, to develop spatial profiles of concentration, streamflow, and load. Numerous main stem and inflow locations...

The following tabs contain sediment transport rates modeled using the Wilcock and Crowe (2003) sediment transport model. The transport rate for each cross section and each scenario are labeled under each tab, which contains all the cross sections from an individual reach. The following tabs contain sediment transport rates modeled using the Wilcock and Crowe (2003) sediment transport model.
This archive contains two files. For Measure Discharges, each tab contains the data and pacific daylight standard time the discharge measurement was taken. The discharge (Q), is calculated using the rating curve developed from measured discharges and water heights recorded from the staff gage. For Modeled Discharges, the following spreadsheets contain discharges modeled from RHYSSES and corrected using measured discharges. The spreadsheets labeled 'discharge' contain the corrected modeled discharge for each flow scenario, from Boulder and Anderson Creek. The spreadsheets labeled 'conversion' contain the calibration relationship used to correct the modeled discharges.

Note: This data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P9A4FVZ4. The data presented here was collected adjacent to USGS stream gage 06730200 and includes both observed and modeled values. Dissolved oxygen, dissolved carbon dioxide, stream depth, water temperature, and light intensity were collected via passive water quality sensors. Modeled values include gross primary production, ecosystem respiration, net ecosystem production, reaeration, and light (when observed values were unavailable). Modeled values were obtained through streamMetabolizer, a USGS-sponsored R-package for estimating rates of stream metabolism. Estimates for carbon dioxide flux utilized both modeled...
The following spreadsheets contain discharge measurements that were used to develop rating curves for each stream gage. The numbers on each tab refer to the date the measurement was collected. Each spreadsheet contains distance, depth, and velocity measurements used to calculate discharge in centimeters and highlighted in yellow.
The following spreadsheets contain pressure and temperature recorded by the barologgers (atmospheric measure) and leveloggers (stream measure) at each stream gauge. Temperature and pressure from stream gauges are needed to calculate discharge, which was in turn needed to calibrate the hydrologic model used in this project.
The following spreadsheets contain pebble counts presented as %finer. Each site name, reach, and cross section are denoted in the rows at the top. Statistical measures including geometric mean and standard deviation for each cross section are enumerated at the bottom

This data release is associated with a journal article titled, "Aquatic-Terrestrial Linkages Control Metabolism and Carbon Dynamics in a Mid-sized, Urban Stream Influenced by Snowmelt." The data were collected adjacent to USGS stream gage 06730200 and include observed and modeled values. Dissolved oxygen, dissolved carbon dioxide, stream depth, water temperature, and light intensity were collected via passive water quality sensors. Modeled values include gross primary production, ecosystem respiration, net ecosystem production, reaeration, and light (when observed values were unavailable). Modeled values were obtained through streamMetabolizer, a USGS-sponsored R-package for estimating rates of stream metabolism....

Daily observed (historical) and RHESSys simulated streamflow under three climate change scenarios for eight Oregon watersheds. RHESSys and SnowModel simulated daily snow water equivalent (SWE) values. Eight Oregon watersheds; 4 within the upper McKenzie River Basin (Anderson, Boulder, McKenzie at Clear Lake, and Lookout), 3 within the Metolius River Basin (Canyon, Jefferson and Jack) and Shitike Creek. See site map and GIS watershed outline layer available. The definition of the files are as follows: Ac_Q.csv = observed and Rhessys simulated daily streamflow; Bc_Q.csv = observed and Rhessys simulated daily streamflow; ccnnnf1234_Q.csv = observed and Rhessys simulated daily streamflow; jcncs_Q.csv = observed and...
