Tried live worms for bluegill. Tons of frogs but haven’t seen any minnows. Hard to see anything with that film on top.the previous owner was a very old woman who was hard to deal with so I haven’t been able to speak to her about anything. I think the pond is at least 40-50 years old. Used to be a huge farm here that was sold off and subdivided in the 70s. Not sure how it’s fed. It may be fed from neighbors pond which is on other side of driveway and a little higher. I see a pipe run under driveway to ours but at the moment the pipe is dry and our creek running from pond is still running. So maybe it’s spring fed. Down creek from the pond I think there are a couple smaller springs because water is just coming out of the ground seemingly from nowhere.
