Thank you to esshup and Cecil for the very helpful advice.

It seems like, although the symptoms looked like whirling disease, it is not that. I don't know how to tell if it is overfeeding or not. I am throwing two large jars full of food per night. The fish are aggressively eating immediately when pellets are thrown. I will post a picture later of the size of the jars.

One thing is that the fish has been spotted twice right where I am feeding, so maybe it is due to feeding? How could I tell if I am overfeeding? 80 10-12" browns were added in the fall and 80 8-10" were added three years ago in the fall. Very few original fish are remaining, to my knowledge. I don't think the pond is at over capacity.

Water quality is something I will look into. The clarity is down this year. We usually have clear water in the spring, but it is murky this year. A pH test kit is coming this week. I'm not sure if that is useful for this situation or not?

Thanks again, everyone.
