OUTPOST.

Castaic Update: The L.A. County Board of Supervisors is scheduled to hear the proposal to privatize Castaic Lagoon on Tuesday at the Hall of Administration, 500 W. Temple St. in Los Angeles.

Meanwhile, Outdoor Safaris International, the concessionaire that would manage the fishing, boating and camping operations for the county should the recommendation be approved, has dispelled any rumors it is pulling out of the process.

``We are still pursuing it. The real plan of action needs to be understood,'' said Steve Miller, OSI's vice president and general manager.

WONna fish? The next whistle stop on the WON BASS-Southern California Region Team Tournament tour is Saturday at Lake Casitas.

Mid-March is the hottest time of the calendar for largemouth bass fishing at the Ventura County lake, as the fish will either be staging on secondary points preparing to spawn or already nesting on their spawning beds. Anglers skilled in the art of sight-fishing will have the upper hand in this contest.

On-site registration will be held at the main launch ramp parking area Friday from 8-10 p.m. and Saturday from 3:30 a.m.-5 a.m. Last year, a record 119 competed. Brothers Nick and Chris Fonseca of Westlake Village and Agoura Hills, respectively, triumphed. Information: [phone].
