Post-wildfire hydrogeomorphic risk management assessment data: 2023 streamflow and precipitation after Grizzly Creek Fire, CO

Metadata:

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Precipitation values are determined to be "true". Quality assurance/quality control checks were completed using time series analysis and visual inspection. Values that were determined to be inaccurate due to potential for precipitation other than rain to have been measured (snow) in the winter months (October - May) and damage to the instrument in September 2023 were removed from the dataset.

Streamflow values are determined to be "true". Quality assurance/quality control checks were completed using time series analysis and visual inspection. Instrument was regularly maintained via cleaning of biofilms and sedimentation and regularly field surveyed allowing for measurement correction.

Logical_Consistency_Report:

Precipitation and streamflow time series plots were visually inspected for consistency throughout the record and compared with other nearby collected data (including precipitation and streamflow from the U.S. Geological Survey) for rainfall and flow event occurrence consistency.

Completeness_Report:

All precipitation and streamflow data collected as part of the JFSP Project Id: 22-1-01-31 are complete and included in this package. Additional collection notes and data use documentation is included within the Grant Final Report (Land and Canham 2024).

Methodology_Description:

The Grizzly Creek Fire ignited on August 10, 2020 near Glenwood Springs, Colorado, USA and burned at total of 132 square kilometers along a 19 kilometer stretch of the Colorado River within Glenwood Canyon. Hydrologic data including precipitation and streamflow were collected by the authors (Utah State University [USU]) from 2020 through 2023, where data collected in 2020 through 2022, were completed as part of prior work and data collected in 2023 were supported by this JFSP GRIN award using the existing hydrologic monitoring network. 2023 data are included within this data package.


PRECIPITATION

We installed one tipping-bucket rain gage (Onset, Bourne, MA) on Spruce Ridge to the southeast of the Grizzly Creek Fire (39.5769, -107.0994). Spruce rain gage was not equipped with telemetry so we downloaded the data during site visits. The precipitation data for each rain gage were processed to identify individual precipitation events.


STREAMFLOW

After the fire in September 2020, we installed a streamflow gage in the Colorado River below Grizzly Creek using a Level TROLL 400 pressure transducer (In-situ, Fort Collins, CO). We collected streamflow data through October 2023 at the Colorado River below Grizzly Creek. The streamflow gages were not equipped with telemetry so data were downloaded manually during site visits. Discharge was calculated from measured pressure using a post-fire survey developed stage-discharge rating curve.

Variables include:

Date and Time = local date time associated with each measurement (mm/dd/yyyy hh:ss)

Seconds = cumulative seconds elapsed

Barometric Pressure (PSI) = absolute 15-minute measured pressure (pounds per square inch [PSI])

Pressure (PSI) = 15-minute measured pressure (PSI)

Temperature (C) = 15-minute measured temperature (degrees Celsius)

Depth (m) = calculated water depth (meters [m]) using measured pressure assuming static pressure

Depth Correction (m) = surveyed depth correction (m)

Corrected Depth (m) = calculated corrected depth (Depth + Depth Correction) (m)
