It seems to me that the frog bite at these small lakes is an early morning or late afternoon deal.

The other day when I got some quality fish on the frog, it was at first light. As I said, the carp were thrashing the grass, moving everything from bass, bluegill and fry around. I think the bigger bass took the opportunity to feed on all the displaced food. I didn't catch the fish in the middle of the grass patches, but off on the edges. They weren't really relating to the grass, but I needed a bait that could chug through it when necessary. On other trips I have caught frog fish early in the morning along the banks, nowhere even near any grass. The frog is just a nice topwater bait that moves and displaces water without seeming too unnatural. Plus you can cast it onto the bank and flop it into the water without fouling the hooks.

The late afternoon bite is more of a grass related bite. The hotter the day, the more likely you'll find fish in the grass. These bass may be lounging in the shade of the grass, or actively feeding in it. The important thing is that the grass provides a structure that bass will use when there really isn't any other structure around(like on park lakes). Cloudy or rainy days won't help pinpoint bass into the grass, they are more prone to be roaming around. Maybe a good time to throw soft jerkbaits or buzzbaits on those kind of days.

Oh, and I always twitch my frog with the rod tip down. When I've fished frogs with my rod tip up, I sometimes pull the bait away before the bass gets it. Another thing, Power Pro braid 30 or 50 pound test will cut right through that grass when you hook up.
