    fished Castaic today for the 1st time this year. For me the bite was moderate and all fish caught in 15 to 20' and the bait needed to be glued to the bottom with the slowest crawl.
    I didnt see any fish up shallow and no signs of beds. My question -- did the spawn here already occur and the bulk is done - or did all this cold rain and new water push the spawn back and it hasn't really started yet?

  • Report: SACRAMENTO, Calif. – The California Department of Water Resources (DWR) will begin implementing additional boating requirements at Castaic Lake in Los Angeles County due to the recent discovery of invasive quagga mussels.

    The discovery of quagga mussels means DWR must implement measures to prevent their spread, including requiring boats to be inspected and drained upon leaving Castaic Lake and Castaic Lagoon. While mussels have not been detected to date in Castaic Lagoon, they are presumed to be present since the lagoon receives water from Castaic Lake.

    DWR and California Department of Fish and Wildlife (CDFW) staff discovered two quagga mussel shells on August 17, 2021, at Castaic Lake. Earlier in the month, a park visitor reported finding a live mussel in the lake. DWR and CDFW have not detected larval “veliger” stage mussels in Castaic Lake during routine monitoring. CDFW and DWR plan to continue monitoring Castaic Lake and Lagoon, and plan to increase monitoring in the Lagoon and Castaic Creek.

    Quagga mussels, which are small, non-native freshwater mollusks, were first discovered in the Colorado River and in California in 2007. In 2016, they were found in Pyramid Lake, the Angeles Tunnel, and Elderberry Forebay. The mussels can be a threat to California’s native species and can clog water systems, colonize hard surfaces, alter food webs in ecosystems, and damage boat engines.

    Boats are required to be inspected by the Los Angeles County Department of Parks and Recreation before leaving Castaic Lake and all water must be drained from outboards, bilges, live-wells, ballast tanks, bait buckets and any other areas containing lake water. Boats must still pass an entrance inspection and be clean, drained, and dry to be allowed to launch. Entrance inspections are still required because they prevent additional invasive species introductions.

    Boats departing Castaic Lake will receive a tag indicating they were last used in a waterbody containing mussels. Tags will allow entry of boats at Pyramid and Castaic lakes without having to be reinspected since both lakes are classified as infested with quagga mussels. After boating in an infested lake, boat owners may experience restrictions or extended dry out periods before visiting another waterbody. Boaters are advised to contact the waterbody destination to be informed of any inspection requirements before their arrival.

    Transportation or possession of live or dead quagga mussels, including water that may contain their microscopic larvae, is a violation of Fish and Game Code 2301 and CDFW has authority to take enforcement action.

    For additional boat cleaning guidelines, go to A Guide to Cleaning Boats ( or DWR’s Quagga Mussels: Clean, Drain, and Dry video.

    Water Clarity: Clear (4+ foot visibility)

    Report: Don Iovino and I got out on the lake for an opportunity to get to know each other. Don taught me his reaper rig, or what he calls "Split Shotting". I threw the rig all day with the intent to step out of my comfort zone. Don hooked into a small keeper on the first stop before I could get my line wet. We picked up 6 fish with 5 keepers. Don taught me a lot. I tried to shortcut the rig and it didn't work too well. Don knows his stuff. He also updated my graphs. You can see it all here:

    Meanwhile......Castaic is filling up. They turned the spigot on and haven't stopped for over a month. Filling it with water that goes through, and was stored in, two quagga infested lakes( Pyramid and Elderberry), and emptying Folsum at the same time. Just kidding about Folsum, but the water apparently comes from Folsum and they have been dumping water at Folsum to where it is now at 40%. All the lakes up North are in "dump mode", dumping water in anticipation of the upcoming snow melt and to maintain control of the water so as to prevent flooding I guess.

    I'm just glad to see water as most of us are. It will take a while for the lakes and fish to recover but at least most of the lakes will be fine. Casitas is still a concern. We still have almost 2 more months of the "rainy season" and Casitas could get enough to add another year to the 4 years the experts say is left.

  • Water Temp: low 60s in most of the coves

    Water Clarity: Muddy (0-2 foot visibility)

    Report: Bite is really picking up on jerkbaits and deeper crankbaits running from 5 feet to 12 feet. Plastics seemed useless for the morning bite. Couple short hits on green with red flake worms. Fished Mar 3rd and picked up 9 averaging around 2 pounds and Mar 10th picking up 14 with little larger females showing up.

    Tips: Used Strike King KVD deep diver jerkbaits and Spro Rock Crawlers seemed to be the ticket for the last few trips.

    Tips: The early top water bite was good in the lake coves near the rocky shorelines. Also drop shotting 4" green worms and wacky rigged 4" inch worms worked well too. The shaky head also played a good roll. It's a tough lake, but the fish are there if you're fishing slow.
