  • Water Temp: 64.3 - 66.7

    Water Clarity: Stained (2-4 foot visibility)

    Report: Launched at 7:30am dropped trolling motor in light rain. S/Waver over dying grass in shallow flats caught a few keepers. Fishing was great, catching was slow for the next couple hours. Mid depth crank, vibrate jig pick up two more. Around 11am went to deeper off shore flat and spooned around bait balls for a couple more, including the best fish of the day just over 2lbs.

    Tips: The lake looked great, we just need over night temps to drop a little and full on fall bite will kick in. I think that is why there were only smaller fish being caught.

  • Water Clarity: Stained (2-4 foot visibility)

    Report: What a nice time to be fishing. Started before sunrise with cloud cover went straight to top water. With one explosion after another life was great. Carbon copy two pounders were showing there colors for the most part. Switched things up and tied on deeper diving crank and went to the flats in deeper water and caught some nicer bass but not by much. Then switched to a chatter bait and went a little shallower and caught a few more. Here is were the fun was though. There were fish busting all over, chasing shad. Tied on a kastmaster on and had a great time Little butter ball bass up to pound or more, so I retied on a ultra lite rig and went to town on them for a half hour or so.

    Water Temp: 57-61

    Water Clarity: Stained (2-4 foot visibility)

    Report: Started at 7am with 6 inch swim bait and caught one 2 lb bass. Through spinners and cranks in shad colors and crawfish, and hooked up a few more bass and even caught a trout on a crank bait.
    City: Napa

    Tips: I was unable to put a pattern together. Even though the lake has not been stocked with trout for a few years, The trout I caught was about 9 inches long. This tells me there are a few babies being born in the lake. A few months from know a nice swim bait will produce. Happy fishin

    Water Temp: 60's

    Water Clarity: Stained (2-4 foot visibility)

    Report: This lake can be tough, Best bet with current conditions is to run to north side work the inlets and the bank on NE side back with watermelon red sekos or tx hogs in wat/red or blue/black on overcast. white on white blades. the gizard shad is in this lake so i use blue back silver speed traps. try a dad like the river to sea yabby the little one and you will get um.
    City: napa/vacaville

    Tips: work from the big inlet in the north back and find em in about 5 to 10.its all sand and run off with perfect bedding areas.

    Report: Fished both the north and southeast sides of the lake. Less than ideal conditions with the wind and the potential for showers. Stuck one LM off a fallen tree and that was it for about four hours of fishing. Spotted lots of fry so it looks like the spawn is over with.
    City: Napa

    Tips: Hennessy is usually a tough lake in the best of conditions, so wait until summer like weather arrives.

    Water Temp: 56 plus

    Water Clarity: Stained (2-4 foot visibility)

    Report: Toaday I was on a walk around the lake on the conn valley side and noticed the bass are starting to bed up. This has been happening for a few weeks now. There were a few pairs stuck together like glue and very aggresive towards intrusive baits laying in there beds. So this is more of an update of the way fish behave. I did stick a few bass.

    Water Temp: 56

    Water Clarity: Stained (2-4 foot visibility)

    Report: Decided to try out my new 10HP out on Hennessy. I love this lake, just can't catch any fish out of it. Like my luck before, NOTHING!!! I thought going between storms might bring out a few momma's.

    The lake is still very low and really doesn't have the structure that it needs but when its full this should end up being a great fishery.

    Most fish were very deep. I threw a basstrix in rainbow trout and finally found a bait that these fish were interested in. They followed the bait up to the boat, sometimes 3 at a time but never grabbed it. SO FRUSTRATING. I stopped it, twitched it, burned it...NOTHING. Again this lake skunked me. Should have just kept driving onto Berryessa like my brain told me to do, again a great day to be on any lake!!!

    Tips: Your asking the wrong guy...I'm the one who needs tips.

    Water Temp: 62

    Water Clarity: Stained (2-4 foot visibility)

    Report: Well here I go again. Nothing, not a even a bite!!!

    I got out before sunrise so I thought there might be a top bite, but ending again without anything. Even tried trolling with a deep diving crank bait, nothing.

    Great day to be on the water but again can't figure out this lake. I guess it's time to start watching football and let the rain fill this lake back up.

    The lake is low and very stained and the fish seem to be sitting around 25 -30 feet. I've made notes on the structure that is present while the lake is low, so when it back up I'll know all the nice areas to hit.

    Thanks to all that have emailed me some tips, keep them coming.
    City: Santa Rosa

    Tips: Good luck, wait until a few more rains.

    Email me if you have any luck with this lake and when it starts producing.

    Water Temp: 72+

    Water Clarity: Clear (4+ foot visibility)

    Report: I've tried this lake out 2 times now and nothing!!! Seems very promising because I can see a lot of fish up against the tules but I never get a bite. I've gotten out very early and the top water bite sucks, I've tried swimbaits, nothing and pluging a jig for them deep, nothing. I chart fish but they are just mouth locked. I've positioned around the drop offs and nothing, not even a bite. The lake is getting low and most likely the ramp will be closed shortly. Love the lake but not the bite. Maybe when the temp drops things will improve if we can still get on this lake. Best part is that when the lake fills back up (hope for big rain this winter) then I'll know all the structure around the lake. Has anyone ever caught a fish outta here???
    City: Santa Rosa

    Tips: Wish I could help. I've fished all the way up the lake arm and nothing. Anyone who knows this lake that can help it would be appreciated. Note: the gate to the ramp is open an hour before sunrise. Hope for rain!!!!
