PRESCOTT, AZ, July 31, 2019 - The Prescott National Forest Burned Area Emergency Response (BAER) team has finished its assessment of the impacts of the Cellar Fire which is now 100% contained. The assessment identified areas of severe burn and potential threats to human life and safety, property, and potential threats to important cultural and natural resources.
The Cellar Fire BAER team has completed its analysis of the fire’s effect on soils, which shows that 25.8% of the fire burned at low severity; 46.5% of the fire burned in moderate severity; and 14.4% of the fire burned at high severity. Given the location of the fire footprint, final assessments indicate minimal values at risk within the fire perimeter or downstream. Any potential post fire risk is within the closure area with a minor runoff risk to values and property downstream. Therefore there will be no additional treatments other than maintaining the closure area through September 30, 2019. This date represents the historic end of monsoons, and therefore the highest likelihood of runoff-related risk will have subsided.
Areas affected by the 2017 Goodwin fire scar’s additional stream flow and sediment delivery will not be affected by additional flows or sediment delivery created by Cellar Fire scar. Almost all of the 7,512 acre Cellar Fire scar is located within the Blind Indian Creek subwatershed, which flows southwest into the Hassayampa River. The fire scar is in the southwestern section of the Blind Indian Creek subwatershed; covering 22 % of the 30,579 acre subwatershed. There will be increased flows and sediment delivery through the southwestern portion of Blind Indian Creek to the confluence with the Hassayampa River. Flood peaks would have dissipated but not altogether attenuate when reaching this confluence. The Prescott National Forest and the Yavapai County Flood Control District have been sharing information throughout the Cellar Fire and BAER response. The Flood Control District have assessed the few structures located on private lands in the affected area and advised land owners of the increased flood risk.
Residents and visitors should not be traveling along roads downstream from the burned areas on the Forest, as these roads are within the closure area. Everyone near and downstream from the Cellar Fire burned area should remain alert and stay updated on weather conditions that may result in heavy rains over the area. Flash flooding could occur quickly during heavy rain events.
