Description:
Abstract:
We obtained data about 168 locations across the contiguous United States (CONUS) that were affected by wildland fire during the period 1984 - 2013. Wildland fire locations, dates, extent, and burn severity were obtained from the Monitoring Trends in Burn Severity (MTBS) dataset. We obtained watershed attributes (watershed boundaries, drainage areas, and perimeters) and daily time series of river flow from the GAGES-II dataset (Geospatial Attributes of Gages for Evaluating Streamflow, version II). The boundaries of the water resource regions were acquired from the Watershed Boundary Database. Climate data were extracted from the daily high resolution (1×1 kilometer) Daymet v3 dataset, and obtained the gridded PRISM (Parameter-elevation Regressions on Independent Slopes Model) dataset. For topographic data (elevation, slope, and aspect), we used the highest resolution version (244×244 meter) of the Global Multi-resolution Terrain Elevation Data 2010, principally obtained during the Shuttle Radar Topography Mission. Finally, we obtained land cover data from the 2001 National Land Cover Database (NLCD).
Purpose:
Wildland fire impacts on surface freshwater resources have not previously been measured, nor factored into regional water management strategies. However, large wildland fires are increasing and raise concerns about fire impacts on potable water. Therefore, we collected data from across the contiguous United States as part of an assessment of these impacts in the 5 years following wildland fire in affected locations, and their management implications.

Process_Description:
Data were collected from a variety of high-resolution datasets describing the conterminous United States landscape with respect to wildland fire, climate, topography, land cover, watershed boundaries, and river flow. Process further described in Hallema et al. (2019).

Hallema, Dennis W.; Sun, Ge; Caldwell, Peter V.; Robinne, François-Nicolas; Bladon, Kevin D.; Norman, Steven P.; Liu, Yongqiang; Cohen, Erika; McNulty, Steven G. 2019. Wildland fire impacts on water yields across the contiguous United States. General Technical Report SRS-238. Asheville, NC: U.S. Department of Agriculture Forest Service, Southern Research Station. 109 p. https://www.fs.usda.gov/treesearch/pubs/58095
Process_Date: Unknown
Process_Step:
Process_Description:
We selected GAGES-II watersheds with a drainage area > 10 square kilometers (km²), approximately the size of a headwater catchment, and a flow record spanning at least 2 decades. In addition, we only selected watersheds with minimal human disturbances or hydrologic infrastructure (e.g., dam, flow diversions, etc.) so the effect of the burn on flow could be isolated from other factors. We combined GAGES-II watershed boundaries with annual MTBS burn severity data, resulting in a dataset with information on burn severity (ordinal classes of underburned or unburned, low, moderate, and high severity) for each 120- × 120-meter (m) subdivision of the burned watersheds. We calculated the fraction of the watershed burned for each burn severity class and for all classes combined. This is the burned area-to-drainage area ratio (BAR).

The resulting collection contained 168 burned watersheds with a BAR ≥ 1 percent for any degree of burn impacts in any single year between 1984 and 2008.
Process_Date: Unknown
Process_Step:
Process_Description:
After identifying the collection of burned watersheds, we retrieved the corresponding fire dates and summarized data for river flow Q, precipitation P, and snow water equivalent (amount of water contained within the snowpack) SWE. Monthly potential evapotranspiration (PET) was estimated from PRISM gridded climate data with Hamon’s method. Finally, we determined for each burned watershed the NLCD land cover and GMTED2010 topographic characteristics such as elevation, slope, and aspect. We also calculated the watershed shape parameter describing the ratio of watershed perimeter to drainage area (Gravelius’ compactness factor).
Process_Date: Unknown
Process_Step:
Process_Description:
To evaluate wildland fire impacts on annual river flow, we
1. Detected river flow change

2. Identified changes in water yield ratio

3. Characterized local wildland fire-climate-environment interactions

4. Filtered local climate baseline

5. Computed net impact of wildland fire on river flow
Process_Date: Unknown

Process_Description:
Predict potential wildfire effects on surface water yield

Used the Water Supply Stress Index model (WaSSI), i.e., the WaSSI monthly water balance subroutine, to obtain full-cover assessment of the potential impact of severe wildfire on surface water yield across the large climatic gradient of the CONUS. We defined four scenarios of hypothetical burn impacts and simulated corresponding changes to the water balance in all CONUS watersheds for the period between 2001 and 2010. By comparing the results of each scenario to a baseline scenario representing undisturbed conditions, we obtained an estimate of their hypothetical impact on water supplies.
