Retardant drops were made by fixed wing aircraft to help slow the spread as the fire burned in steep and inaccessible terrain. Crews are also using tactical firing operations to help establish containment lines as conditions allow. Firefighters continue to be challenged with high temperatures, critically dry fuels and drought stressed trees. Mandatory evacuations remain in place. The fire started in the Angeles National Forest near Lake Hughes. It is moving north and west burning in 100-year-old fuels consisting of Big Cone Douglas Fir, Oak and Gray Pine. The fire remains eight miles northeast of Interstate 5 and south of Highway 138. Containment along the west flank of the fire will continue to be threatened by spot fires and long-range spotting. Long range spotting is a behavior of fire that produces sparks or embers which are carried by the wind causing fires out ahead of the main fire.

  • DWR Scheduled Maintenance at Castaic Lake February
    l 27234 Bouquet Canyon Rd., Santa Clarita, CA 92350 | (661) 297-1600 | yourscvwater.com NEWS RELEASE DATE: February 11, 2020 FOR IMMEDIATE RELEASE DWR Scheduled Maintenance at Castaic Lake SCV Asked to Step Up Water Conservation Efforts Next Week Shutdown of Facilities at Castaic Lake for Routine Maintenance Scheduled February 18-22 SCV Water is asking customers to limit their outdoor water use next week, February 18-22, in preparation for annual maintenance on facilities at Castaic Lake. The SCV will rely exclusively on local groundwater sources and treated imported water stored at reservoirs throughout the Valley. Ahead of the shutdown, SCV Water will fill all of its storage facilities to capacity, with more than 92 million gallons of water. “About half of the SCV’s water supply is local groundwater, while the other half is imported from the State Water Project and other sources,” said Gary Haggin, SCV Water operations and maintenance superintendent. During the shutdown, California Department of Water Resources (DWR) will be replacing a 132” valve in its distribution system. SCV Water has no planned maintenance or repair work associated with this shutdown. WATER SUPPLIES Haggin added, “With the scheduled shutdown of facilities, the water from Castaic Lake will be unavailable for use. The water will be in the lake; we just won't be able to receive it while the facility is undergoing upgrades and annual maintenance.” Haggin also noted that this one-week conservation initiative is not a reflection of SCV Water’s overall water supply. It's merely a response to the temporary disruption of water delivery while key infrastructure is taken out of service for repairs, maintenance and upgrades.

  • Ventura County
    Steelhead/rainbow trout resources of Ventura County Rincon Rincon Creek consists of about 9.7 stream miles. It flows southwest, entering the Pacific Ocean at Rincon Point. The culvert at the Highway 101 crossing is a total passage barrier (Stoecker et al. 2002). A watershed plan prepared for Rincon Creek includes a review of historical steelhead information. The review notes O. mykiss stocking occurred in the 1940s and subsequently. Anecdotal accounts of trout observations from the 1950s to the 1980s also are included (Tetra Tech 2007; Stoecker et al. 2002). Rincon Creek was surveyed in 1993 and no fish were observed. The survey report states, “Sediment inputs from Casitas Creek are destroying downstream habitat” (Unknown 1993). A 1994 DFG memo relayed the results of surveys from that year. The memo states, “The Wheeler Fire [in 1985] could have been the event that eradicated rainbow trout from Rincon Creek, although there is anecdotal information from a landowner along Rincon Creek that suggests that the population was extirpated as early as the 1960’s” (DFG 1994a). The memo adds, “It appears that the Highway 101 culvert has prevented the recolonization of rainbow trout/steelhead in Rincon Creek” (DFG 1994a). Consultants surveyed Rincon Creek as part of a steelhead study, and observed O. mykiss likely representing one year class in 2001 (Stoecker et al. 2002). A 2002 memo from NMFS staff states, “Rincon Creek provides approximately 4 miles of steelhead spawning and rearing habitat…” (NMFS 2002a). A 2002 study report notes water quality impacts on Rincon Creek from the large sediment load carried by Casitas Creek, a tributary (Stoecker et al.
