The fact that there were multiple blue herons mean there were lots of fish.
Not necessarily. The herons might be eating tadpoles for all you know. Maybe the lake dried up to just some puddles, but toads or frogs filled the puddles with eggs, and now the herons are chowing down on the tadpoles since it's January and abundant food in shallow water is hard to come by. Or it could be minnows from the creek - interesting to the herons but not to you.
If the lake goes completely dry from time to time, and it's that shallow, I wouldn't pay $5 to fish it unless I talked to someone in advance and they confirmed what fish were stocked, how much stocking the pond gets, and when it was last stocked. Otherwise, it's a sucker bet.
I might make an exception if there were crowds of people fishing the pond all the time - that might be a sign that there's something there worth trying. But if I had to guess, if it's on the "honor system" and it isn't fished much, then most likely the pond owner doesn't put much time into it and just keeps a "money box" out in case gullible passers by like yourself decide to check it out.
Really shallow ponds have a lot going against them. If they go dry, obviously all the fish are dead. In the hot summer, they can lose all their oxygen and have a die-off even if the pond isn't dry. They have algae blooms. In the winter, if they freeze over, they can become oxygen-depleted and "winter kill" (though that shouldn't be a problem this year since we keep ticking along about 15 degrees above normal average temperature for this time of year). I'd avoid this one unless you have a convincing reason to think otherwise, or you just have so much money that you can kiss $5 goodbye without a worry.
