I went to Granbury for the first time this weekend in my kayak and we put in next to a bunch of flooded bushes with some small trees mixed in. Average depth was only a few feet, and was close to the Blue Branch creek channel and a shoreline with good green grass and reeds. I ran a buzz bait and a swim jig through the brush and near some grass early and missed a couple and got one chunk. Then I left the area due to not having much confidence in fishing it once the sun got up. No hits on a frog near the reeds.
After some research it seems pitching a creature bit or jig would be good, along with a swim jig and spinner bait.
The specific area was just east of the ramp pictured below. It is all under water now so you may need to know the area.
Any tips will be much appreciated!
