      It was, but the grass is starting to take over. I didn't have to many clean casts. Most every one I had to clean grass off of what I threw.

    6.0 in. Largemouth Bass with a Rapala Jointed Deep Husky Jerk

      Yep...it was the only bite I got in nearly 5 hrs. Why was this little fish so aggressive when the others could not be enticed to bite or strike. The water is still ...more pretty warm (72F).

      When they hit lures as big as them, you gotta wonder " what are they thinking"?

    Good morning bite, but the action died down once the sun came out. On the water for four hours. Still figuring this place out. This one was the highlight of the ...more day at almost 3 1/2 lbs.

    3 lb. 6 oz. 18 in. Largemouth Bass with a Gary Yamamoto Original Senko Worms

      Thanks Frank, have to write that one of my list ! Maybe we will meet up some day at Moraine and talk !

      Ted, the channel is there. The weeds are choking up the water up to about 1-2 ft. of the surface even in the channel.

      Very nice Frank!

      Frank, thanks for the info. I've been thinking about that place for awhile. There used to be a decent channel going through there which I fished.
    7. Frank Yamada 0
      Jim, bite has been slow, at least the couple of times I’ve been there. Ted, the upper part of the lake is almost completely choked off with weeds (and very, very ...more shallow).
    8. Ted Gerle 0
      Nice fish ! I haven't fished there in many years, but the upper no motor section was always good for me.
    9. Jim Leise 0
      I haven't made it up there yet this year. I haven't had much luck up there the last couple years I went, and heard the bite was still slow. Used to be ...more one of my favorite places to go, glad you got some going!

      Nice! Big lake; lots to figure out. We’re hoping to get up there soon.
