| PROJECT DESCRIPTION |
| |
The 2009 Station Fire was the largest fire in Angeles National Forest (est. 1892) recorded history and burned over 160,000 acres in the San Gabriel Mountains. Approximately 87% of the watershed tributary to Big Tujunga Reservoir was burned, making sediment deposition inevitable during subsequent storm events. The storms that occurred in the wet seasons after the fire increased sediment accumulation in the reservoir by more than one million cubic yards.
The sediment in the reservoir can impact the operation of the valves and reduce the capacity for water conservation and flood control. Sediment removal is necessary to maintain the operability of the dam and protect the communities and environment downstream of the dam.
Pursuant to the California Environmental Quality Act (CEQA) a Mitigated Negative Declaration (MND) has been prepared. See project meeting and review period details above in the Announcements and the Environmental Documents section.
Pursuant to the National Environmental Policy Act (NEPA) an Environmental Assessment (EA) is being prepared. A public scoping meeting was conducted by the United States Forest Service on July 24, 2012 in Tujunga, CA and included this linked Big Tujunga Presentation. A public review period for the draft EA will begin in fall 2013.
