This is what I've found so far. Thanks for the replys.
The April stocked fish were probably stressed from the trip, handling, or from temperature stress. Maybe it was passed to the previous inhabitants by contact during feeding or as an opportunistic pathogen during stress from spawning or possible decreased immunity during the Spring warmup.
May treat with antibiotic feed or let it run its course, not sure if the potassium permanganate bath is doable. This is all new to me. I knew it would be fun, but not this much. Any other comments from people who have experienced this problem would be greatly appreciated.
