I'm not sure where Pollywog lake is in Grant county? I live in Pendleton county and have fished most bigger lakes Corinth,Willianstown,Boltz,and Bullockpen, along with Eagle Creek. I always did well taking my kids to Leary lake at Loydd WMA on highway 491 in Crittenden.Leary has a good population of decent Bluegill and LM Bass.My youngest hooked a 5 lb 2 oz LM on his snoopy pole with shiners on a bobber near the handicap access dock about 7 years ago,little guy fought it until his arms wore out and I had to land it for him.
There is plenty of bank access at Leary,I guess the downside is it gets fished heavy.If you need any info on Pendleton or other Northern Ky counties I'd be glad to help anyway I can.
