I have been fortunate enough to have fished Wriggleswade a number of times with Basswacker Roy Jacobs before he immigrated. Three spots I can direct you to:
1)The pump house area to the right of the slipway. Crank the banks and cast parallel to the cement walls. There are also a number of submerged trees in the vicinity, so target with a texas rigged plastic bait.
2)Graveyard - from the slipway keep left and turn into the first bay on the left hand side. The point on the left hand side is pretty rocky and a good spot for targeting early morning or late afternoon fish.
3)If you proceed straight you go up the river which has a gazillion trees. Navigate carefully and try and go up as far as you can. Work your way back fishing Horny toad, buzz baits, spinnerbaits and crank. You can also pitch jigs/plastics to the trees - try and target the thickest limbs first.
Good luck
