RIM BAER UPDATE
SONORA CA
(September 16 2013) – The BAER team completed the soil burn severity map
for the Rim Fire. The map using burned acres as of September 13 shows
that approximately 56% of the 254 926 acres within the Rim fire
perimeter are either unburned or received a low-severity burn 37%
sustained a burn of a moderate severity and approximately 7% burned at a
high severity. BAER specialists concluded that the amount of high severity burn is fairly low given time of year and comparison to other fires. The moderate and low severity burned areas are fairly high for similar reasons. These values are for the entire burn area of the Rim Fire.
The Rim BAER assessment specialists continue their burned area field surveys. The BAER specialists expect to complete their field surveys by Friday September 20. The BAER Soils Scientists and Hydrologists began their analysis of their field data for modeling predicted post-fire water run-off and erosion risk levels. The BAER team is also coordinating and sharing their field data with the US Geological Survey (USGS) who are modeling for debris flow potential as well as other interested agencies and entities such as Natural Resources Conservation Service (NRCS) Tuolumne County Hetch Hetchy Water and Power and Turlock Irrigation District.
Utilizing data that was collected in the BAER field surveys meeting with the Stanislaus National Forest its stakeholders and interagency cooperators the post-fire hydrologic models potential values at risk and emergency determinations for the Rim burned area are expected to be finalized by the BAER assessment team by the end of this week.
BAER Interagency Liaison Officer Sherry Hazelhurst said “The BAER team anticipates presenting its final assessment report to the Stanislaus Forest Supervisor by Wednesday September 25 who will forward the BAER report onto the Forest Service Washington Office for its review approval and funding.” The BAER team’s analysis and report will be shared with the public.
Emergency stabilization treatments are expected to begin this week and fire suppression repair is ongoing.
