The Basin Complex Fire burned 240,00 sq/mi of then northern Santa Lucia mountains in the summer of 2008.

A watershed-related issue examined by the ENVS 560/L Watershed Systems class at CSUMB.

Basin Complex burn area, 2008[1]

Summary

In the summer of 2008, the Indians and Basin Complex fires started separately and then merged into one fire. The Indians fire, started by a campfire, burned 81,378 acres of the south eastern Santa Lucia mountains of Central California between June 8th and July 10th. The Basin Complex Fire, started by lightning, burned 162,818 acres of the northern Santa Lucia mountains between June 21st and July 28th[1]. After a wildfire there is major concern about the possibility of flooding, debris flows and other large scale erosion in the years following the fires[2]. These events potentially endanger the Big Sur and Carmel Valleys, Salinas farm land, steelhead habitat, Highway 1 and numerous federal and state recreation areas. There has been work aimed at understanding the effects of fire on soils, debris flows and erosion. There is little understanding of the effects of post-fire erosion and debris flows on river habitat, and specifically steelhead habitat.

Location

The Basin Complex-Indians Fire burned approximately 240,000 acres in the northern Santa Lucia Mountains. The fire burned parts of the Upper Carmel River, Arroyo Seco, San Antonia, Rat Creek, Big Sur and Little Sur watersheds. and portions of Fort Hunter Liggett. Much of the land burned is within the National Forest System lands on the Monterey District of Los Padres National Forest[1].

Resource/s at Stake

There is a broad range of resources at risk after wildfires. Risks related to the Basin Complex Fire included: Big Sur and Carmel Valley communities, Salinas Valley farm land, Highway 1, numerous state parks and camp grounds, private residents and essential steelhead salmon habitat.

Stakeholders

Jurisdiction

Assessment of the burned area fell under the jurisdiction of the US Forest Service and California Forestry and Fire Protection (CalFire). CalFire was the lead agency for the assessment. The policies of both agencies are to provide rapid assessments of the burned areas and suggest best management practices to avoid further damage from erosion and debris flows.

Future Research

Future work should seek to understand the impacts of rain on the burned area. The greatest hazards to the communities of Big Sur is flooding and debris flows. The in stream habitats of threatened steelhead will also be effected by erosion and debris flows. There is little understanding of the direct effects of post-fire erosion on steelhead habitat.
